Our Platform and Infrastructure/Site Reliability teams report into the same leadership, which ensure seamless cross-team collaboration. Platform engineers here don\'t just build APIs in isolation, they work hand-in-hand with SRE to think about how systems run, scale, and recover in production. It\'s a setup that rewards engineers who care about the full lifecycle of the software they ship. The backend powers everything from fraud detection and transaction classification to data ingestion and third-party integrations. We are a high performing team where engineers have significant ownership over core systems. There’s no separate “architecture layer”—the people writing the code are the ones making the decisions. We\'re a hybrid team based in Greenwich Village, NYC, and we\'re looking for someone local to the Greater NYC area who will attend the office Tuesdays through Thursdays. What you\'ll be doing As a Senior Platform Engineer, you will: Architect and build backend systems. You\'ll own features end-to-end: from database design through to API endpoints, triggered events, and data pipelines. That means collaborating with Solutions Architects and Product Managers to spec out what clients actually need, then making it real in Node.js with a Postgres backend. Partner with Infra and SRE. With Platform and Infra/SRE under the same roof, you\'ll be involved in conversations about reliability, deployment, and production health– not just as a consumer of infrastructure, but as a collaborator. Observability, failure modes, and operational readiness are part of how we build at Alloy. Drive platform-level initiatives. Beyond feature work, you\'ll take on the kind of foundational improvements that make the whole team faster and more resilient, whether that\'s improving data ingestion pipelines, tightening up integrations with third parties, or reducing toil for the engineers around you. Own incident response and follow-through. When things break, you help get them back up. More importantly, you stick around for the blameless post-mortem and make sure the same thing doesn\'t happen twice. Mentor and multiply the team. You\'ll be given the trust and authority to tackle ambiguous, high-impact problems end-to-end, making architectural tradeoffs that hold up in production, and raising the bar for how the team builds and operates systems. Who we’re looking for Experience: 8+ years of production software engineering experience, with a track record of owning meaningful backend systems on a collaborative team. Technical depth: Strong command of our core stack, or the clear ability and willingness to get there fast: Node.js (TypeScript preferred) Data systems expertise: Deep expertise in relational databases and experience with analytical databases. You think in terms of query plans, indexing strategies, and data access patterns. Our data layer powers real-time decisions and analytics, so you’re expected to actively optimize how services interact with databases for performance, scalability, and reliability. Cloud expertise: You’re comfortable designing systems in public cloud, understand tradeoffs between managed services and custom infrastructure, think about scalability, reliability, and cost as first-class concerns Observability Nice to have: Experience designing high-throughput data pipelines, working with event-driven systems, or operating services under real production load is a strong plus. Collaboration over credentials: We care far more about how you think, communicate, and work with others than about your degree or resume formatting. If most of your experience is through contracting or ambitious personal projects, tell us about it, we\'re open! Ownership mindset: You don\'t wait to be told what to fix. You notice problems, flag them, and help solve them. We\'re a lean team, so your impact will be felt immediately, and opportunities will grow as the company scales up.
