Senior AI / Full-Stack Engineer

• Background in B2B SaaS or product-led companies.

• 5+ years of full-stack development experience, with strong fluency in either TypeScript/Node or Python (ideally both) and a modern frontend framework (React, Next.js, or Angular).

• Hands-on agent work: tool or function calling, multi-step orchestration, retrieval, structured output, evals, guardrails, and managing cost and latency.

• Production-level use of AI coding tools (Claude Code, Cursor, Copilot, etc.). You have shipped LLM features to paying B2B customers.

• Hands-on experience with CI/CD, containerization (Docker), and at least one major cloud (GCP, AWS, or Azure). Solid grasp of DevOps fundamentals: IaC, monitoring, logging, alerting.

• Comfortable working in a fast-moving environment where priorities shift and you're expected to own outcomes.

• Very strong written English (C1 or C2). We write things down.

• You work well as a peer on a team of senior engineers: you review their code, and they review yours.

Responsabilidades: • Own features end to end: the React and Next.js front end, the TypeScript APIs, Postgres, and the deploy. Must have strong PR hygiene.

• Design, build and ship LLM agents and features in our product: tool calling over our APIs and data, multi-step workflows, retrieval and structured output.

• Build the evals, guardrails and logging that prove those features work, and keep the cost and latency of each model call in check.

• Turn vague problems from contractors (project managers, superintendents, foremen) into scoped features and talk to those users when it helps.

• Ship small, frequent releases through CI/CD: automated tests, a staging environment, container deploys on Google Cloud.

• Translate requirements into clean, tested, maintainable code with strong PR hygiene.

• Use AI coding assistants every day and share the workflows with the team.

• Work directly with product, other engineers, and occasionally customers. Bridge feature work and infra reliability. Review code thoughtfully and mentor where it helps.

Deseable: • Prior startup experience where you were the only owner of an area.

• A background in construction, the trades or field services.

• Google Cloud, especially Cloud Run.

• Multi-tenant SaaS.

• Terraform and GitHub Actions.

• Public work that shows how you build with AI: open source, write-ups or talks.

Beneficios: • Health: $150/month health and wellness stipend.

• Engagement: B2B contract. 30-day mutual notice.

• Fully remote. We are based in Denver, Colorado (MT, UTC-7). There must be significant overlap with US business hours.

• Async-first. Docs, Loom, and well-written PRs are the norm. Meetings happen when they're the fastest path to clarity.

• Small team, direct access. No middle layer between you and the people making decisions. Your work ships fast.

• Latest tooling. We use the best AI tools available and expect you to do the same.
