Senior Software Engineer; AI-Native

Position: Senior Software Engineer (AI-Native)
HOW WE WORK — AI-NATIVE ENGINEERINGAt B-Stock, AI is not a side experiment — it is how we build. Our engineers work in an AI-first workflow: using agentic coding tools to design, write, review, test, and ship production software, orchestrating AI to multiply their output while keeping human judgment firmly in the loop. We are looking for engineers who already work this way, or are hungry  this role you will be expected to:

Use AI-assisted and agentic development tools (e.g., Claude Code, Cursor, Git Hub Copilot) as a daily, core part of how you deliver — not an occasional aid.

Orchestrate one or more AI agents across parallel work-streams, and know when to trust, verify, or override what they produce.

Bring strong engineering judgment to reviewing and validating AI-generated code — you own the output, the AI does not.

Decompose ambiguous problems into clear specs and prompts that an AI can reliably execute against.

Stay fluent in a fast-moving toolchain and help raise the bar for how the whole team works with AI.Bonus: experience building AI-powered product features — LLM integration, retrieval, evaluations, or agentic systems in production.
