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.
Research / Full-time
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.
Engineering / Full-time
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.
Product / Full-time
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.
