Internship @ Sqwish (AI Research / Backend / ML Engineering)

About Sqwish Labs

At Sqwish Labs we build the infrastructure that lets AI products learn from real production outcomes, so signals like customer resolution, conversion, trust, time saved, safety and cost can shape what the system does next.

The work is hard in the best way. Part of it is research: learning from messy, delayed, real‑world feedback instead of clean benchmarks. Part of it is engineering: building reliable infrastructure that can sit inside live AI systems and make good decisions request by request.

Position Overview

This is a flexible internship in Cambridge that can be remote or in‑person, shaped around one of two tracks: AI Research / Engineering or Backend Engineering. You might work on experiments, evaluations, reward signals, and model behaviour; or on APIs, data pipelines, infrastructure, observability, and production systems that power the learning loop.
