About the job
About the job



Mesta is a global FIAT + stablecoin payment network processing transactions across 180+ countries. We combine traditional payment rails (SWIFT, SEPA, ACH, UPI) with blockchain infrastructure (Ethereum, Solana, Polygon, Tron) to move money across borders — instantly and at a fraction of the cost. Our API-first platform lets businesses go live in days, with built-in compliance, real-time tracking, and support for 50+ currencies.



 Role Description:



We're looking for a strong backend engineer to build and scale the core of our real-time transactions engine. You'll work across the full spectrum — integrating banking APIs one day, optimizing stablecoin settlement flows the next. This is a high-impact, early senior hire where your code moves real money across the world, 24/7. You'll have the opportunity to shape engineering culture and grow into a leadership role as the team scales.



This is a full-time. Candidate needs to be based in the United States, preferably in the San Francisco Bay Area. 



 Qualifications:



 • 3–8 years of backend engineering experience building distributed systems or high-throughput platforms

 • Proficiency in Node.js/NestJS or TypeScript (or similar backend stacks — Java, Go, Python)

 • Strong experience with PostgreSQL, Redis, and event-driven architectures (SQS, Kafka, etc.)

 • Cloud-native experience with AWS, Docker/Kubernetes, and CI/CD pipelines

 • Performance mindset — you instinctively profile, measure, and optimize

 • Ability to design and build scalable, secure APIs (OpenAPI, OAuth2/JWT)

 • Comfort with ownership and fast iteration in a startup environment

 • BS/MS in Computer Science is great, but proven experience and skills matter more



 Nice to have:



 • Experience with payment systems (RTP, SWIFT, SEPA, UPI, ACH)

 • Blockchain familiarity (stablecoins, smart contracts, L2 networks)

 • Workflow orchestration (Netflix Conductor, Temporal)

 • Observability tooling (Grafana, Prometheus, NewRelic)

Security/compliance awareness (SOC2, PCI-DSS)
