What You'll Do:

You'll be the technical lead for a backend product line in our data and analytics platform. The platform lets healthcare marketers and analysts work with privacy-protected real-world data, run queries at scale, build audiences and use AI-assisted workflows. You will own the architecture of high-throughput, secure backend services built on Java and Spring Boot, and help shape the technical roadmap.

- Provide technical leadership for your product line. Own the architecture of backend services, including service boundaries, data modelling, storage choices and scalability.

- Design multi-tenant, privacy-first data flows across services and environments, with healthcare compliance in mind.

- Lead cross-team initiatives end to end, from design through rollout, working closely with Product, Infrastructure and partner teams.

- Build and evolve data-intensive and asynchronous systems using distributed query and processing engines, workflow orchestration and messaging platforms such as Kafka. Use datastores like Redis (caching, counters, rate limiting, locking, pub/sub) where they fit, alongside relational and analytical stores.

- Lead the integration of AI into our products and engineering workflows. This includes LLM-powered features, agentic workflows, retrieval over metadata or documents, and tool integrations via the Model Context Protocol (MCP). Design for grounded output, human approval, cost control and measurable quality.

- Establish engineering best practices for API design, code quality, testing, security and data privacy.

- Design observability (metrics, logging, tracing, alerting) with tools such as Grafana and Prometheus. Lead deep-dive investigations into production issues and run blameless postmortems.

- Mentor senior and junior engineers through design reviews, code reviews and pair programming.

- Champion responsible AI-assisted development and set standards for how engineers use coding agents and AI tools.

- Drive knowledge sharing through documentation, design forums and internal talks.

Who You Are:

- 8+ years of backend engineering experience, with a track record of designing and delivering large-scale distributed systems in production.

- Deep expertise in Java (17+) and the Spring ecosystem (Spring Boot, Spring Data), including JVM internals, concurrency and performance tuning.

- Solid experience with relational and NoSQL or analytical databases (such as MySQL, PostgreSQL, Cassandra or ClickHouse), including schema design and query optimisation.
