Job summary

ExTrac AI in London is seeking a Senior Software Engineer to join our engineering team to build and operate the services and pipelines powering our decision-support platform.

The role spans API design, data pipelines, cloud infrastructure, and deployment tooling.

• Solid understanding of distributed systems, databases, and software engineering patterns.
• Experience with cloud infrastructure and infrastructure as code, and with the CI/CD pipelines around them.

• Take an ambiguous problem, gather requirements, write a technical design, and ship to production with minimal oversight.
• Own services end to end, including consolidating or decommissioning what they replace.
• Contribute to and lead system design and architecture decisions.
• Design APIs used by both internal teams and customers, and hold them to clear contracts and sensible versioning as the number of consumers grows.
