Senior Developer Success Engineer

About us

Relay is a cross-chain payments protocol that provides instant, low-cost cross-chain bridging, swaps, and transactions. We're the fastest and cheapest way to bridge and transact across chains, serving over 5 million users who have completed 59+ million transactions with $6+ billion in volume across 85+ chains.

Our company mission is to make transacting across chains as fast, cheap, and reliable as online payments. We are building the core infrastructure to abstract chains from end user payments, enabling the next billion users to experience the benefits of blockchain without the UX burdens.

About the role

We're hiring a Senior Developer Success Engineer to make Relay the easiest way for developers to move value onchain. You'll work directly with integrators, get complex implementations across the finish line, and turn what you learn into a better product for everyone who follows.

You'll partner closely with our Customer team: they own the commercial relationship, you own the technical one.

What you'll do

Cover US business hours

• This role is remote within the United States, with a strong preference for Eastern Time.

Own integration support

• Own the technical relationship when developers need help integrating with Relay

• Debug directly with developers, drive issues to resolution, and make sure the same problem is easier—or unnecessary—the next time

• Know when the answer is better guidance, a better implementation, or a better product

Work directly with integrators

• Work alongside developers from first integration through healthy production

• Help integrators choose the right path through Relay and get complex implementations across the finish line

• Move easily between a partner call, a broken integration, a code sample, and a product decision

Build what scales

• Turn repeated integration work into docs, examples, templates, and tooling other developers can use

• Treat documentation as part of the product, not something that trails it

• Write for developers—and the agents increasingly working alongside them

Close the loop

• Be Relay's most informed voice on where integrations break down and why

• Turn what you learn from developers into better APIs, workflows, and product decisions

• Measure success by whether developers integrate faster, with less help, over time

About you

• You treat every integration issue as a product problem, not just a ticket to close

• You're technically strong enough to prototype, debug, test, and verify integrations independently

• You can explain APIs clearly in writing and in conversation without losing technical precision

• You establish practical standards for writing, improving, and publishing developer documentation

• You notice repeated friction and turn it into a better default

• You can move between technical and non-technical audiences without losing precision

• You're comfortable building a new function in a fast-moving startup

Skills and abilities

Must-have

• 5+ years in Developer Success, Developer Relations, or Solutions Engineering—or similar experience in software development

• Ability to prototype, debug, test, and verify production integrations independently

• A body of developer-facing work—documentation, examples, demos, or tools—that made a technical product easier to use

• Strong technical writing and communication skills

Nice to have

• Experience with API-first, infrastructure, payments, fintech, or crypto products

• Familiarity with SDK design, API evolution, and developer tooling

• Experience building documentation or examples for AI coding agents

• Experience with TypeScript and modern web development
