Jack’s take. Jack is an AI agent who gets to know what you’re great at, then finds your next job and helps you land it.
“The posting calls this a software-engineering job. You would own architecture, deployment, and production operations, and research teammates would keep the longer experiments.”
Who it suits
A good fit
- have deployed machine-learning models rather than only trained them
- like making a heavy vision model fast enough for an annotator to use it live
- want the engineering job on a team that also has researchers
Think twice
- want the research job, with longer experiments and prototypes
- haven’t served a model in production
- don’t want 4 or more days a week in the London office
What you’d do
- You’d design, build, and run the infrastructure that serves computer-vision and multimodal models.
- Serve models fast enough that annotators get suggestions while they work, and send their corrections back as feedback.
- Precompute model outputs across very large video sets, watching throughput, GPU cost, and reliability.
- Build agent-based quality checks into the product.
What they ask for
- You have 5 or more years of software engineering, including time running machine-learning systems in production.
- You can own architecture, implementation, deployment, and production operations.
- You’ll be in the London office 4 or more days a week.
How it works
- Most of the team is in the London office 4 or more days a week.
