The Role:

We’re looking for a Lead R&D Engineer who thrives on building and experimenting, someone who’d rather have a working prototype by Friday than a perfect plan by next quarter.

You will help lead a small, high-autonomy team focused on rapid experimentation at the intersection of AI and document workflows. Your job is to explore what’s possible through building proof-of-concept products, putting them in front of users, learn from the feedback, and iterate relentlessly. Some things will work and will ship, and some won’t. The point is to move fast enough to find the ones that matter and the ones that stick. The learning and the iteration is as important as the outcome.

To be clear, this isn’t a role for someone who wants to polish requirements docs or have the perfect architecture. It’s for someone who can leverage AI to build at pace, who has deep user empathy, who questions the status quo, and who thrives on the ambiguity of figuring out what the right thing to build even is.

Your work will span building new web and desktop applications, AI assistants, intelligent document processing, workflow automation, MCP servers, and AI services that integrate with Nitro’s API platform and existing products.

What you’ll be doing:

Helping lead a small R&D team focused on building experimental document workflow solutions, from concept to working prototype

Rethinking how people work with documents, building and shipping proof-of-concept products fast, gathering real user feedback, and iterating based on what you learn

Designing and building cloud AI services using modern frameworks and generative AI technologies

Building solutions including AI assistants, intelligent document processing pipelines, automation workflows, and MCP servers

Using AI-assisted development tools aggressively to dramatically accelerate how the team builds

Setting technical direction for the team while staying deeply hands-on

Collaborating with other engineering teams, product, design, and customer teams to identify high-impact problems worth solving

Evaluating emerging technologies and pulling them into Nitro’s platform where they create real value

Championing new ideas across the organisation and helping successful experiments and prototypes get to production

What we’re looking for:

A builder first mentality

Experience building modern software, with strong full-stack skills (JavaScript/TypeScript frameworks, Python)

Real world hands-on experience building AI or LLM-powered applications not just experimenting, but shipping them

Deep fluency in modern AI development patterns such as embeddings, RAG, prompt engineering, tool use, agent architectures

Experience building and deploying cloud-native applications on AWS or Azure

Demonstrated ability to rapidly prototype and ship working solutions in short timeframes

Strong architectural instincts balanced with pragmatism

Comfort with ambiguity - you don’t need a detailed brief to get started.

Experience mentoring or leading engineers, with the ability to set technical direction for a team

Excellent communication skills you can motivate a team and explain a prototype’s value to an engineer, a PM, or a customer

You actively use AI coding tools to write code faster and to take on full agentic code authoring and have a desire to go even further.

Bonus points for:

Previous experience in innovation teams, R&D groups, or startup environments

You’ve built something from scratch that people actually use

Experience with ML model development (TensorFlow, PyTorch) from data wrangling to production

Experience integrating LLMs with APIs, automation frameworks, or developer platforms

Experience building agent-based systems or AI assistants

Experience with vector databases, embeddings, and RAG pipelines
