Senior Backend Software Engineer

Senior Backend Software Engineer - Build the evals and automation behind AI-driven insurance operations. Remote (US, Canada, Europe).

Our client’s platform ingests billions of unstructured data points every day and turns them into precise, explainable insights that insurers rely on for high-stakes decisions.

You’ll join the team that evaluates the core operations workflow from first principles, building the back-office automation pipeline and the central evals framework that drives continuous improvement.

What You’ll Do

• Lead the design and delivery of complex Python services, data models and asynchronous pipelines on AWS

• Build and scale LLM-based systems that process large volumes of unstructured documents with precision and explainability

• Design external-facing APIs and integrations that customers depend on

• Own database performance as data volume grows, TechTree combines AI agents with a human support team to give candidates a better, more transparent hiring experience.

Our AI Agent gets to know your background, experience, and what you’re optimising for. It continuously matches you to live roles across our network where there’s genuine alignment, not just keyword overlap.

Our Human Team is there to support you through the process - answering questions, adding context, and making sure you’re never left guessing or ghosted.

• Strong Python, AWS serverless (Lambda, Step Functions) and asynchronous workflow experience

• Strong relational database and PostgreSQL performance tuning skills

• Experience building external-facing APIs or third-party integrations

Bonus: LLMs in production, document pipelines, distributed systems, or insurance/fintech experience.

Salary: $192,000-$246,000 USD (location-dependent) plus significant equity.

This is a role that TechTree is recruiting for on behalf of one of our clients.
