About This Job
Trách nhiệm chính
- Design, develop, and operate backend services that remain correct and available for millions of users, ensuring graceful degradation when upstream services fail.
- Build and integrate APIs and event-driven services (REST, gRPC, Kafka) along with external third-party systems.
- Use AI coding tools heavily, taking full responsibility for everything shipped with them.
- Own architecture decisions that are expensive to reverse: service boundaries, data modeling, failure modes, migration sequencing.
- Optimize performance and data access across our stores (MySQL, MongoDB, Redis, Elasticsearch, HBase, ClickHouse), choosing by access pattern rather than familiarity.
- Treat user content reaching models as untrusted input, handling prompt injection, input validation, output validation, and PII redaction.
- Build the data and feature plumbing our ML systems depend on — streaming features, batch scoring, analytics pipelines.
Yêu cầu
- Bachelor's degree in Computer Science, Software Engineering, or equivalent practical experience.
- 5+ years building and operating backend systems that real users depend on.
- Solid grasp of OOP, design patterns, concurrency, memory management, and profiling.
- Depth in at least one statically-typed language on a managed runtime, in production. We work on the JVM (Java/Vertx); if your depth is elsewhere, we'll trade ramp-up time for judgment.
- Proficiency across SQL and NoSQL stores (MySQL, MongoDB, Redis, HBase, or similar) — including knowing which one a problem actually calls for.
- Experience with OLAP / analytics pipelines / data warehousing (ClickHouse, BigQuery, or equivalent).
- Comfortable with Docker, Kubernetes, and at least one major cloud.
- Sense of ownership: you follow your service into production and you're on the hook when it misbehaves.
- You work fluently with AI coding assistants and agents (Claude Code, Cursor, Codex, or similar) — and you can articulate where they help, where they hurt, and how you verify their output.
