Burgess Hills, UK
Onsite to 3 days per week
We expect you to understand how your tools function beneath the syntax:
- Deep knowledge of runtime behavior (e.g., JVM memory model, garbage collection mechanics, thread pools, event loops, or coroutines).
- Clear mental models of networking, HTTP protocol mechanics, connection pooling, and serialization overhead.
- Concrete understanding of database internals (e.g., indexing mechanics, locking mechanisms, query execution plans, and transaction isolation levels).
2. Architecture & Deliberate Trade-Offs
You must be prepared to articulate and defend engineering decisions:
- Justify architectural choices: Monolith vs. Microservice, REST vs. GraphQL, synchronous RPC vs. event-driven pipelines.
- Weigh trade-offs across consistency, latency, network payload sizes, and developer ergonomics when designing client-facing data layers.
- Navigate database selection (relational SQL vs. NoSQL document/key-value stores) based on query patterns, access frequency, and data integrity guarantees.
3. Production-Grade Enterprise Reliability
Financial platforms require defense in depth and fault containment:
- Proactive defensive programming, strict input validation, data masking, and adherence to enterprise security standards.
- Resilient dependency management: zero cascading failures when downstream services degrade or fail.
- Clean code fundamentals: clear separation of concerns, high-signal automated tests, and readable abstractions that support team velocity.
Qualifications & Skills
Baseline Requirements
- Proven track record building and operating server-side applications and distributed microservices in production.
- Solid experience designing and consuming RESTful APIs and event-driven architectures with Apache Kafka.
- Hands-on database exposure across relational databases (e.g., PostgreSQL, Oracle, MySQL) or NoSQL data stores (e.g., MongoDB, Cassandra, DynamoDB); balanced exposure to both paradigms is highly valued.
- Experience with automated testing suites (unit, integration, regression) and modern CI/CD automation tools.
- Strong debugging, root-cause analysis, and performance optimization skills.
Preferred Technical Stack & Experience
- Legacy Modernization: Comfort diving into legacy enterprise codebases, identifying domain boundaries, and safely migrating functionality to modern services without downtime.
