• Design and deploy scalable Python backends on GCP to handle real-time control, market dispatch, and grid-aware optimization algorithms.
• Collaborate directly with founders and clients to iterate on the API infrastructure that enables third-party device participation in energy markets.

The ideal candidate

• Proven production experience shipping B2B SaaS products using Python backends and cloud platforms like GCP or similar.
• A track record of solving deep technical problems in distributed systems, complex integrations, or high-traffic data pipelines at a scaling startup.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
