• Build and maintain extensive unit test suites to ensure reliability, quality, and long-term maintainability of microservices.
• Support the rewrite of ingestion capabilities by developing new Python Lambda microservices and extending TypeScript data pipelines.
• Help rewrite the initial part of the data pipeline to support high-throughput analysis.
• Improve the observability of conversations flowing through the platform and ensure issues can be identified and diagnosed efficiently.
• Contribute to the initiative starting Q2 2026 to rebuild both the phone application and web application to surface more meaningful conversation insights.
• Work effectively within a small team, delivering work both independently and collaboratively.
• Collaborate with the Technical BA to assist with refining tickets and clarifying requirements before implementation.

• Proven ability to work with legacy codebases and modernise them into scalable, maintainable solutions.
• Strong unit testing skills and experience building reliable automated test coverage.
• Strong problem-solving skills with a detail-oriented mindset.
• Ability to work in a balanced way across collaboration and independent delivery.

Nice to Have:
