(Remote anywhere in Colombia. Independent-contractor (prestación de servicios) engagement — long-term, full-time-scale workload. See Role structure below.)

Are you a senior engineer who is tired of shipping through four layers of reviews and waiting two quarters to see anything reach production? Would you rather your work go live the day you write it and see the impact that same day in revenue? If you are principled, self-disciplined, comfortable owning systems end to end, and looking for real autonomy, read on.

Jewel ML is an AI-native e-commerce personalization platform powering iconic retailers such as Guess, Calvin Klein, Coach, American Eagle, West Elm, Pottery Barn, Banana Republic, and many more. We receive many billions of behavioral data points daily to train our AI models and serve hundreds of millions of users globally through our partner integrations.

We are searching for a senior full-stack engineer to work alongside our remote engineering team and take end-to-end ownership across our cloud-native stack. You will work directly with leads, clients,



and other functions across the org to ship your work. The right candidate is genuinely comfortable in both the backend and the frontend, has run production systems on a major cloud, is willing to learn frontier ML and AI concepts, and is the kind of engineer who balances velocity and quality in their day-to-day work in a high-performance environment.

Minimum requirements:
6+ years building and running production software, including:
Polyglot full-stack: deep TypeScript/Node and Python.
JavaScript in the wild: vanilla-JS widgets injected into other companies' live storefronts — DOM, CSS cascade, bundling, browser APIs.
Services at scale: Express and FastAPI on a sub-150 ms hot path; caching, batching, graceful degradation.
GCP (or equivalent major cloud) end to end: Cloud Run, Batch, Composer, MIGs, Pub/Sub, Docker, CDN, Terraform, K8s, GitHub Actions — you own your own deploys.
3+ years of hands-on experie
