Technical Solutions Engineer

About the role

Coinme is part of Polygon Labs, and together we're putting out a stablecoin payments stack: our fiat on and off ramps, Sequence wallets, and settlement on Polygon. Fintechs and financial institutions are integrating it now, and the documentation hasn't caught up. Partners are asking questions that should have been answered in a doc six months ago, and those questions land on engineers who need to be building. This role fixes that.

What You'll Do

• Own the API and integration docs. Rewrite what's wrong, fill what's missing, keep it current as the stack changes
• Build the quickstarts, sample code, and reference architectures that get a developer from nothing to a working integration
• Answer technical questions from partners during sales conversations and during builds, and resolve them yourself rather than passing them to engineering
• Take signed partners live: requirements intake, provisioning once KYB and KYC clear, sandbox testing, webhooks, go-live checks
• Work with the integration program manager on timelines so partners know what's coming and when
• Learn the stack deeply: CaaS ramps, Sequence wallets, Trails, OMSX, bank rails, custodial and non-custodial flows, virtual accounts, deposit addresses, webhooks
• Build demos and sample apps that BD can use to show what the products do
• Push what you learn back into Product and Engineering. You'll see every rough edge in the API before anyone else does
• Automate the repetitive parts of onboarding and provisioning, and use AI tools to move faster on docs and support
