Co-CTO

Help Build, Lead and Scale Tono, a Next-Generation B2B SaaS Platform

Remote-first | Flexible Commitment | Approximately 15–20 Hours per Week | Equity Participation

Would You Like to Help Build a European SaaS Business?

We are looking for an experienced, entrepreneurial Software Architect and Technology Leader to join the founding team behind Tono.

This is an opportunity for someone with a strong software engineering background who wants to do more than write code. You will help shape technology and product decisions, drive development initiatives, contribute to customer discussions and play an active role in building the business.

We have already developed a comprehensive B2B SaaS platform and are approaching our next important phase: product refinement, commercial launch, customer implementations and international expansion.

You will not be joining a project that exists only as an idea or a PowerPoint presentation. You will be joining a business with an established software platform, a founding team, a clear product strategy and an experienced advisory board.

We are looking for someone who has both the ambition and the capability to take meaningful responsibility for what comes next.

About Tono

Tono is a Danish technology company developing an External Workforce Governance Platform for organisations that engage external consultants, freelancers and professional services providers.

In many larger organisations, external workforce management remains fragmented across different systems, spreadsheets, emails and manual processes.

This makes it difficult to maintain a consolidated view of who is working for the business, what they are delivering, how much they cost and whether contractual and compliance requirements are being met.

Tono has been designed to address this challenge.

Our platform connects three key participants within one integrated environment:

• Enterprise clients engaging external expertise.
• Consulting firms and staffing suppliers providing specialist resources.
• Individual consultants and freelancers delivering the work.

The platform supports the processes associated with sourcing, skills matching, contracting, approvals, assignment management, time recording, invoicing, financial visibility and compliance.

A fundamental principle behind Tono is that all three participants work with relevant shared information relating to the same engagement, rather than maintaining separate and disconnected processes.

Tono also incorporates functionality for assessing and documenting compliance risks, including worker classification and cross-border engagement considerations.

Artificial intelligence supports selected workflows, including skills profiling, drafting requirements and candidate matching, while retaining appropriate human oversight.

Our ambition is to make external workforce management more connected, transparent and efficient for everyone involved.

We are initially focused on the Nordic market, with the longer-term ambition of building a competitive European software business.

The Opportunity: Co-CTO and Member of the Founding Team

As Co-CTO, you will become a key technology and business partner to our existing CTO, Chief Product Officer and CEO.

The role combines hands-on software engineering, solution architecture, technical project leadership and commercial collaboration.

You should be equally comfortable discussing code and architecture, reviewing a product roadmap, resolving development challenges or explaining a technical solution to a prospective enterprise customer.

You will be expected to take ownership of development activities from initial requirements through to implementation, while maintaining a broader perspective on what makes sense for Tono technologically, operationally and commercially.

Importantly, you will complement our existing CTO, not replace them.

We want to bring together complementary technical expertise within a small, ambitious founding team, sharing responsibilities according to experience, individual strengths and the needs of the business.

The precise division of responsibilities between the CTO and Co-CTO will be agreed collaboratively.

Your Key Responsibilities

Software Engineering & Architecture

Contribute directly to the continued development of Tono's C#/.NET-based platform, helping maintain a robust, scalable and maintainable software architecture.

Technical Project Leadership

Translate product priorities and business requirements into structured development activities, realistic delivery plans and clearly defined milestones.

Take ownership of progress, identify dependencies and ensure that technical initiatives move forward.

Product Development

Work closely with the CTO and Chief Product Officer on product architecture, technical solutions, user experience and roadmap prioritisation.

Help maintain the right balance between functionality, technical quality, development effort and commercial priorities.

Pre-Sales & Customer Engagement

Participate in technical presentations, product demonstrations and workshops with prospective enterprise customers.

Be able to explain Tono's architecture, integration capabilities, security considerations and technical approach in language that both technical and business stakeholders can understand.

Engineering Quality & Best Practice

Contribute to code reviews, testing strategies, development standards, automation, CI/CD, performance optimisation and the management of technical debt.

Help establish practical engineering disciplines appropriate for a growing SaaS business.

Enterprise Readiness

Support the platform's ability to meet enterprise expectations regarding security, availability, access management, documentation, integrations and operational reliability.

Strategic Collaboration

Participate actively in discussions with the founding team concerning technology, product strategy, customer needs, commercial priorities and the future development of the company.

Future Scaling

Help establish the engineering practices, technical processes and organisational foundations required as Tono acquires customers and expands internationally.

About You

You are likely to have spent several years in a role such as:

• Senior Software Engineer
• Lead Developer
• Software Architect
• Engineering Lead
• Head of Software Development
• CTO or Technical Co-Founder

You are, first and foremost, a highly capable software engineer and architect. However, you also have the motivation to take on broader responsibilities and contribute to building a business.

You have substantial practical experience with C# and .NET, including the development and maintenance of professional software applications in production environments.

You understand the principles behind modern SaaS platforms, including software architecture, data modelling, APIs, integrations, scalability, information security, performance and maintainability.

You are confident making sound technical decisions without introducing unnecessary complexity.

Experience with enterprise applications, cloud-based systems, SaaS products or technical product leadership would be particularly valuable.

Familiarity with AI-assisted software development tools, such as Cursor, is also relevant, as these technologies already form part of our development approach.

Your Mindset Matters as Much as Your Technical Expertise

We are not necessarily looking for the candidate with the longest list of technologies on their CV.

We are looking for someone with strong technical judgement, intellectual curiosity and an entrepreneurial mindset.

You are comfortable working independently, but you also enjoy discussing ideas, challenging assumptions and developing solutions collaboratively.

You can explain and defend a technical decision, while remaining open to changing direction when a better approach emerges.

You work in a structured manner, take ownership of your commitments and communicate clearly about progress, challenges and opportunities.

You appreciate that a startup does not always have perfect processes, unlimited resources or complete specifications.

You are pragmatic without compromising the engineering quality that matters for the long-term success of the product.

Above all, you are attracted by the opportunity to help build a company in which your contribution and decisions can make a genuine difference.

How We Work

Tono currently operates as a remote-first team.

We work from different locations and place considerable emphasis on flexibility, trust, open communication and individual accountability.

We have two scheduled online stand-up meetings each week, where we coordinate activities, review progress, discuss challenges and agree priorities.

Additional online meetings take place whenever technical or commercial matters require collaboration or joint decisions.

We expect you to be engaged, accessible and proactive in your communication.

In return, we are not concerned with where you work or precisely when you complete your tasks.

What matters is progress, quality, reliability and effective collaboration.

We envisage an initial commitment of approximately 15–20 hours per week.

This makes it possible to maintain other professional commitments, provided that availability, engagement and any potential conflicts of interest can be managed appropriately.

We see this as a long-term partnership rather than a short-term development assignment.

More Than a Technology Role

One of the most interesting aspects of this opportunity is the breadth of the responsibilities involved.

You will not simply be helping us improve an existing software platform.

You will also contribute to answering the fundamental questions that arise when a technology product develops into a commercially successful business.

For example:

• How do we balance product development priorities with the requirements of prospective customers?
• How do we deliver new functionality efficiently while maintaining the architectural quality required for future growth?
• How do we prepare a platform for enterprise-level requirements without creating unnecessary organisational complexity?
• How can we use AI and modern development practices to increase engineering productivity and improve the quality of our solutions?
• And how do we gradually build a technology organisation capable of supporting a growing international customer base?

As Co-CTO, you will help shape the answers to these questions.

You will be involved in decisions that extend well beyond software implementation.

What We Offer

This is not a conventional full-time employment opportunity.

It is an opportunity to join an existing startup as Co-CTO and Technical Co-Founder, with meaningful influence over the product, technology strategy and future direction of the business.

We offer a flexible, long-term commitment with the opportunity for equity participation. The specific ownership structure and commercial terms will be agreed individually.

You will have the opportunity to work with an established technology platform and a founding team bringing complementary expertise in software engineering, product development, business development and the external workforce industry.

Tono also benefits from an experienced advisory board with backgrounds in major enterprises and relevant professional disciplines.

We have an ambitious vision, but we also recognise that building a successful technology company requires engineering excellence, commercial discipline and consistent execution.

That's why we are looking to strengthen our founding team with an additional senior technical leader.

Interested in an Initial Conversation?

If you are an experienced Software Engineer, Software Architect or Technology Leader looking for greater influence, broader responsibility and the opportunity to build something with long-term potential, we would welcome a conversation.

You do not need to have decided on a startup career, nor do you need to leave your current position simply to explore the opportunity.

What matters most is your technical experience, entrepreneurial outlook and willingness to make a meaningful contribution.
