Senior Fullstack Engineer
About The Position
Blackbird Labs is a loyalty and payments platform establishing meaningful connections between the world’s best restaurants and their customers. Served up in 2022 by Ben Leventhal, co-founder of Eater and Resy, Blackbird offers a fully customizable loyalty programming platform for restaurants and a consumer app designed to make every guest feel like a bonafide VIP no matter where they dine. Backed by Union Square Ventures, a16z, Amex Ventures, Variant Fund, and other forward-thinking investors, Blackbird is out to revolutionize the restaurant industry. Blackbird is looking for a Senior Fullstack Engineer to own Flycar, our restaurant payments terminal used by thousands of restaurants. You'll build the software servers and managers rely on during every service, where downtime means a dining room that can't close checks. This is a Next.js/TypeScript monorepo powering multiple apps across payments, loyalty, and restaurant operations. You'll work primarily in Flycar but contribute across the platform.
Requirements
- 5+ years with React and TypeScript
- Experience with real-time data (WebSockets, polling) and graceful degradation on unreliable networks
- Track record shipping software where failure has immediate, visible consequences — payments, POS, fintech, or similar
- Comfort working across the stack: reading API contracts, debugging queries, reasoning about system design
- Strong ownership instincts in a small, fast-moving team where scope is fluid
Nice To Haves
- Experience with payments infrastructure, POS systems, or restaurant/hospitality tech
- Background in multi-tenant systems or hardware-constrained environments (terminals, kiosks)
- Exposure to blockchain, crypto, or web3
- Experience with Datadog, Amplitude, or similar observability/analytics platforms
Responsibilities
- Own end-to-end development of Flycar - UI, API integration, WebSocket flows, and fallback handling when things go wrong
- Build interfaces that work reliably across FSR and QSR environments with inconsistent hardware, spotty networks, and dozens of POS configurations
- Drive frontend architecture decisions — you'll shape how we build, not just what we build
- Debug real-time payment flows that span our terminal, mobile app, and backend services
Benefits
- Depending on your work location and experience the target annual salary for this position can range from: [$180,000-$240,000] USD. This range does not include the equity component of the overall compensation package.
- Disclosure in accordance with New York City's Pay Transparency Law.
