Senior Software Engineer, AI-Native/First

THE ROLE: You'll design, build, test, deploy, and maintain scalable applications that millions of people will touch every month, and the infrastructure underneath them. You'll work across the full lifecycle: system architecture, backend services, integrations, performance, reliability, and security. You'll also provide technical leadership. That means shaping engineering standards, reviewing code, sharing what works, and mentoring less experienced engineers. We build AI-first. We expect you to be operating at the edge of what agentic development tools can do, and to bring the rest of the team with you.

WHAT YOU'LL DO: Design, build, and ship production features across our Type Script stack on AWS, working with Postgres, Redis, and event-driven architectures. Own services end-to-end, from schema design and implementation through deployment, monitoring, and incident response. Use CLI, IDE, and autonomous agent workflows as your default mode of building, not as a side experiment. Build and improve the internal patterns, prompts, and guardrails that make agent-assisted development reliable for the whole team. Improve and maintain CI/CD pipelines that keep us shipping with confidence multiple times a day. Collaborate with data and product to design and run experiments. Contribute to architectural decisions and trade-off discussions with direct, honest input. We attack ideas, not people. WHAT WE'RE LOOKING FORAI-native/first practice, non-negotiable: Fluent across CLI, IDE, and autonomous agent workflows (Claude Code, Cursor, Codex, or equivalent) and understand fully about how they're changing the craft. Hands-on AI engineering with LLM-powered systems: evals, prompting, structured outputs, model behavior, or agent workflows. You push the boundary of what's possible with AI-assisted development rather than waiting for it to settle. Engineering foundation:3+ years of professional software engineering experience with a strong foundation in Type Script and Node.js. Deep AWS experience: ECS or Lambda, RDS (Postgres), Elasti Cache (Redis), SQS and SNS, Cloud Watch. You've built and operated production systems here, not just deployed tutorials. Relational database fluency: schema design, query optimization, migrations, and operational awareness with Postgres. Enterprise B2B cloud software background. You've worked on systems where uptime, data integrity, and auditability actually matter. CI/CD ownership. You've built or meaningfully improved deployment pipelines and believe shipping safely and often is a core engineering responsibility. Monitoring and observability mindset. You instrument your code, set meaningful alerts, and investigate anomalies proactively. Comfort with ambiguity. We're iterating fast. Requirements shift. Context is incomplete. You thrive here because of the uncertainty, not despite it.
