What you'll do
- Design and ship moderate to complex backend features with minimal guidance, choosing between modular-monolith code, shared components, and independently operated services
- Influence team objectives, technical direction, and long-range goals, partnering with product managers and designers to shape requirements around user needs
- Define backend standards for style, maintainability, testing, application programming interfaces (APIs), and operational readiness, advocating for quality, security, availability, and performance
- Mentor associate and intermediate engineers, remove technical blockers, and improve delivery practices through code and design reviews
- Diagnose and prevent performance and reliability issues at scale, participate in incident response, and act as a technical owner where appropriate
- Experiment with and integrate agentic AI into production engineering workflows, evaluate its effectiveness, and coach others on responsible use and sound judgment
What we're looking for
- Strong command of backend architecture, APIs, data systems, and performance tuning in a complex product or service environment
- Proficiency in modern backend languages and a deep understanding of systems programming, with the ability to learn and adapt rather than mastery of a single language
- Experience designing or evolving modular backend boundaries, bounded contexts, and migration-safe architectures
- Ability to lead through influence, technical judgment, and clear asynchronous written communication, connecting product needs with technical decisions and directing your own work
- Experience building or operating agentic AI systems in production, including loops, tool use, and error-handling strategies that support reliability at scale, beyond prompt engineering alone
Nice to have
- Experience with high-throughput distributed systems, concurrency or profiling
- Containerized production operations (such as Kubernetes)
- Database performance (PostgreSQL, ClickHouse, schema evolution or partitioning)
- Large-scale modular monoliths or event-driven systems
- Public technical communication, open source maintenance or developer-focused software as a service (SaaS)
