We're building for mission-critical use cases.

sunbow.ai is built for work where better AI can materially improve outcomes. The team combines deep research expertise with practical engineering for customers who need reliable systems.

Open positions

Research Engineer Build training and evaluation systems for specialist models that improve in production.

Location: San Francisco / Remote

You will work across model training, evaluation design, data pipelines, and applied research loops with customers who need domain-specific performance.

We are looking for engineers who can move between experiments and production systems, write clear evaluation code, and reason from evidence rather than vibes.

Machine Learning Engineer Turn customer workflows into reliable model training, serving, and feedback systems.

Location: San Francisco / Remote

You will build the systems that make specialist models practical: training jobs, inference paths, observability, deployment tooling, and feedback ingestion.

This role is a fit for someone who likes pragmatic ML engineering, clean infrastructure, and close collaboration with users.

Product Engineer Design and ship the interfaces that help teams deploy, evaluate, and improve their models.

Location: San Francisco / Remote

You will own product surfaces for model evaluation, workflow configuration, deployment visibility, and customer feedback loops.

We value engineers who care about detail, speed, reliability, and interfaces that make complex systems feel understandable.
