About the company

Our client is an early-stage software company.

The role

Raydar is recruiting for this role on behalf of our client. Own and build core product functionality end to end as a hands-on individual contributor, working in close partnership with a co-engineer. The focus is on designing automated systems that monitor and improve themselves, while integrating cutting-edge models into a fast, reliable user experience.

What you'll do

- Own the core product across front end and back end, sharing coverage with a fellow engineer.

- Design self-improving automation that reviews error logs, applies fixes and reports changes for human review, rather than patching issues one by one.

- Integrate a range of current and specialized open-source models so the overall pipeline feels fast and seamless.

- Work toward shorter processing times, lower cost per output, a more delightful user experience and greater system stability.

- Collaborate with a machine learning engineer to train small on-device models for specific parts of the pipeline.


Requirements

What we're looking for

- 3 to 8 years of engineering experience.

- Deep, demonstrable experience in building agent-based harnesses and automation that improves itself.

- Well-rounded generalist skills, solid in both front end and back end without being narrowly specialized.

- Close familiarity with the latest model developments, open-source models and agentic pipelines.

- A track record of building something comparable, for example as a core engineer or core open-source contributor.

- Strong individual contributor who can hold a whole system in their head, not a people-management profile.

- High agency, low ego and real interest in creative media tools.

- Comfort with an intense, all-in startup pace.

Bonus points

- A creative side, such as making music or content, with real artistic intuition.


Benefits
