Under-the-Hood Engineering DepthWe 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 ● Languages: Java, Kotlin, or equivalent modern server-side languages. ● API Technologies: REST, GraphQL, RAML, OpenAPI/Swagger. ● Build & Delivery: Gradle, Maven, Git, Docker, Kubernetes, Jenkins/GitLab CI. ● Legacy Modernization: Comfort diving into legacy enterprise codebases, identifying domain boundaries, and safely migrating functionality to modern services without downtime.
