Build the Rails for Global Stablecoin Payments
About the Role
Stable Sea is looking for a founding Backend Engineer to design and build the core infrastructure that powers cross-border payments and stablecoin treasury management.
You won’t just be adding endpoints—you’ll be laying the rails: architecting systems that talk to banks, payment processors, and blockchain networks like Stellar, Polygon, and Starknet. This is a high-ownership role for someone who thinks like a founder: obsessed with reliability, comfortable with ambiguity, and excited to ship quickly in a fast-moving environment.
If you want your code to sit at the heart of real-money flows, this is that role.
What You’ll Do
Design and build core backend services and APIs in Golang that power our products end-to-end.
Integrate with banks, payment partners, and blockchains to support stablecoin flows, FX, and cross-border use cases.
Own performance, reliability, and scalability of critical systems, with a strong focus on transaction integrity and security.
Collaborate directly with founders, frontend engineers, and compliance to take features from idea → design → production.
Monitor, debug, and improve production systems—you care deeply about uptime, latency, and correctness.
Shape our DevOps discipline (CI/CD, observability, testing) and help define how we build and ship software as we scale.
What You Bring
~4+ years of backend experience (or equivalent impact), ideally in fintech, payments, or blockchain.
Strong proficiency in Golang, or deep experience in similar languages plus a willingness to ramp on Go quickly.
Hands-on experience with blockchain integration (Stellar, Polygon, Starknet, Ethereum, Solana, etc.).
Solid foundation in system design, API design, data modeling, and cloud-native architecture.
Experience with SQL/relational databases and data integrity in transactional systems.
Understanding of security and compliance in financial applications (encryption, KYC/KYB, auditability).
A builder / founder mindset: you take ownership, move fast, sweat the details, and are comfortable making tradeoffs with imperfect information.
Nice to Have
Experience with stablecoins, on/off-ramps, or cross-border payments.
Familiarity with Layer 2 networks and smart contract design patterns.
Knowledge of event-driven architecture and distributed systems.
Experience deploying to AWS or GCP using containers or serverless.
Exposure to tools like Terraform, Docker, Prometheus, Grafana, or similar.
Why Join Stable Sea
Work on real financial infrastructure that moves money across borders using stablecoins and traditional rails.
Join as an early technical leader and shape our architecture, standards, and engineering culture.
Collaborate with a small, senior, low-ego team that ships quickly and cares deeply about quality.
Remote-friendly, flexible environment.
Competitive compensation, benefits (healthcare, 401(k) with contribution), and meaningful upside as we scale into new corridors and products.
