Senior DevEx Engineer - Infrastructure

Your tasks

You will own the systems and engineering practices that help development teams deliver reliable software while improving the overall developer experience. Your responsibilities will include:

• Own the internal developer platform end to end, including CI/CD pipelines, build and deployment workflows, canary and blue-green releases, self-service tools, and ephemeral environments.
• Design and implement AI-enabled development workflows, building tools and automation that help engineers collaborate effectively with coding agents while maintaining speed, quality, and safety.
• Measure developer productivity and software delivery performance, identify bottlenecks, and implement improvements based on data rather than assumptions.
• Take operational ownership of the infrastructure you build, ensuring reliability and participating in the Core Infrastructure on-call rotation.
• Define technical direction and establish engineering standards for how teams build, configure, test, and deploy services.
• Mentor less experienced engineers and promote sound engineering practices across the organization.
• Collaborate with product engineering teams to improve developer tools, frameworks, internal APIs, and the overall experience of building and maintaining applications.
• Develop and maintain standardized development pathways, reducing repetitive application boilerplate and providing reliable, well-supported tooling for common engineering tasks.
• Share technical decisions, trade-offs, and learnings transparently across a fully distributed team.
• Continuously explore opportunities to improve infrastructure efficiency and integrate emerging AI capabilities into engineering workflows.

Requirements

The ideal candidate combines strong cloud infrastructure and platform engineering expertise with a genuine software engineering background. They should be comfortable taking ownership of production systems, working autonomously, and navigating evolving technical challenges. Key qualifications include:

• Strong experience with cloud infrastructure, preferably AWS; substantial experience with Google Cloud Platform (GCP) is also considered.
• Hands-on experience with Kubernetes in production environments.
• Practical infrastructure-as-code experience using Terraform, Pulumi, CloudFormation, Ansible, or a comparable solution. Terraform is preferred but not mandatory.
• Strong CI/CD expertise, including ownership of build, test, deployment, and preview-environment workflows.
• Experience measuring and improving software delivery performance using DORA, SPACE, or similar engineering productivity frameworks.
• Demonstrated ability to operate production systems, troubleshoot incidents, and participate in an on-call rotation.
• A solid software engineering background, including building and maintaining applications or products rather than focusing exclusively on infrastructure tooling.
• Strong understanding of developer experience and code ergonomics, with the ability to create tools and workflows that engineers find practical and intuitive.
• Excellent asynchronous communication skills and the ability to collaborate effectively within a remote, geographically distributed team.
• A proactive, independent approach to problem-solving, with the ability to manage work from initial discovery through implementation and production ownership.
• Comfort working in an environment where priorities evolve, requirements may be ambiguous, and technical direction must often be established through experimentation.

Additional experience that would be advantageous includes

• Hands-on experience with AI development tools, coding agents, or large language model (LLM)-based engineering workflows.
• Familiarity with Model Context Protocol (MCP) servers and agent integration patterns.
• Experience in payments, fintech, or other regulated industries.
