Job summary

Workstream is a mission-driven startup building AI-native services for the hourly workforce. As the first Staff engineer on the AI-Native Services team, you will lead zero-to-one work, shape architecture, and set engineering bar with real influence over growth and productization.

You will own components, not pricing or margins, and drive reusable agent-based solutions. You will partner with design customers, map live data workflows, and build evals, human-review tooling, and robust incident

Qualifications

• You have built and operated at least one AI agent or agentic workflow in production.
• Strong engineering judgment across models, orchestration, APIs, data and integrations, permissions, observability and evaluations.
• You have worked directly with customers or end users and communicate clearly with non-technical people.
• You can break messy workflows into deterministic steps, agentic decisions, human judgment and exception paths.
• You care about keeping plausible but wrong AI output away from customers: grounded context and verification.

Responsibilities

• Build and operate production agents and agentic workflows: orchestration, tool use, data connections, deterministic logic, state, and permissions.
• Work forward-deployed with design customers—sit in their workflow, map the reality, and build against live data.
• Build the evaluation harness: eval datasets, pre-launch thresholds, regression suites, and post-launch monitoring.
• Build the human-review layer: exception queues, review tooling, escalation paths, and auditable traces.
• Run shadow-mode parallel runs and drive discrepancies to zero before go-live.
• Turn customer-specific work into reusable agents, integrations, and playbooks—productization is the default.
• Handle production incidents end to end and feed failures back into evals and controls.
• Help set the technical bar as the team grows.
