About Stainless

Stainless is a fast-growing tech startup building the future of APIs. Our customers include industry leaders like OpenAI, Anthropic, and Cloudflare.

We have raised over $35 million from a16z, Sequoia, and founders/C-levels from Stripe, Datadog, Segment, Linear, and more.

We are headquartered in NYC, just west of SoHo, and expect to grow from ~20 to ~40 people in 2025.

Position overview

Support Engineers are the direct interface between Stainless and our users. You’ll work with all Stainless users, from those just starting on their integrations to those that have been with us for years (like OpenAI and Anthropic). You’ll be the voice of the customer to the rest of the company, advocating for them and directly influencing the roadmap of the company both immediately and longer term.

To excel in this role you will have strong independent judgement and can write software in a wide variety of programming languages (maybe from prior experience or picked up on the job). You learn quickly and can jump into unfamiliar contexts (and repositories) with ease.

We’re growing the team from 2 to 4 (and beyond) and you’ll be laying down the foundation of how we support our customers now and in the years to come.

• You love connecting with new users: learning their needs and coming up with creative solutions to solve them

• You care deeply about great communication about technical subjects, from terseness of a tweet to an expanded tutorial in documentation

• You’re a quick learner, self-motivated, and able to execute quickly whilst maintaining high quality

• You love crafting a great product. You appreciate and show extreme detail-orientation in articulating papercuts and finding every possible corner of polish
