Claude Code, Cursor, multi-agent setups, MCP servers, whatever ships next, you're using it and pushing it to its limits. We move fast on adopting what works * That said, you know how code and systems actually work. You can debug, reason about architecture, and carry your weight in a codebase without an AI assistant holding your hand. * Strong work ethic - you take ownership, ship what you commit to, and don't need to be chased Nice-to-haves * Strong opinions about observability , structured logging, distributed tracing (OpenTelemetry), dashboards and alerting built for on-call humans, not vanity metrics * Experience operating event-driven architectures under load (SQS, Kafka, or similar) , you know what failure looks like before it becomes an incident * Familiarity with data warehousing / analytics (e.g. ClickHouse, Snowflake, or similar) ## Description * Stack: AWS · Terraform · NestJS · PostgreSQL · GitLab CI/CD * You work directly with stakeholders - no walls, no ticket factory. * Manage AWS infrastructure - architecture, reliability, security, and cost. No infrastructure team above you. * Design and maintain CI/CD pipelines that let engineers ship confidently and fast - from commit to production with zero manual steps. * Sometimes we ship fast to learn, sometimes we slow down to fix the foundation - you'll help decide where to lean. * Real influence on architecture and product direction, not just coding tickets. * Help us adopt the latest AI improvements to speed up how we build and ship.
