## About the Role

* 5+ years of experience building production software
 * Strong experience with TypeScript / Node.js and modern full-stack systems
 * Deep knowledge of PostgreSQL, including query plans, indexing, replication, and production performance
 * Strong distributed systems fundamentals, particularly idempotency, transactional boundaries, race conditions, and retry semantics
 * Experience owning production observability using Datadog, OpenTelemetry, or similar tooling
 * Track record of diagnosing complex production issues and solving the underlying root cause
 * Ability to operate with high ownership and independently drive complex engineering projects, * Experience building payments infrastructure, including payment processors, EMV terminals, preauth/capture flows, or PCI-adjacent systems
 * Background in POS, commerce, inventory, or reconciliation
 * Experience with Next.js, tRPC, Prisma, ElastiCache, Aurora/RDS, RDS Proxy, PostgreSQL, or pgvector
 * Experience building or operating high-volume transactional systems
 * Familiarity with AI coding tools such as Claude Code, Cursor, Codex, or Devin
 * Experience establishing technical standards or architectural principles across engineering teams
 * Exposure to production LLM, recommendation, OCR/CV, or agent-based systems

## Description

The platform handles real-world transactions for local retailers across point of sale, payments, eCommerce, inventory, and other core store operations, giving you the opportunity to build infrastructure that directly impacts businesses every day., * Own the transactional core responsible for recording sales, with a focus on idempotency, race conditions, split payments, and correctness

 * Build highly reliable payments infrastructure, including processor integrations, routing, retries, pre-authorization recovery, and reconciliation
 * Lead observability across Datadog, including APM, RUM, DBM, structured logging, tracing, monitoring, and DORA metrics
 * Optimize a high-volume PostgreSQL environment through query plans, indexing, read replicas, N+1 elimination, and caching
 * Design architecture for high-write transactional systems, multi-location businesses, and offline-resilient checkout
 * Establish engineering patterns around transactional boundaries, caching, instrumentation, and reliability
 * Use modern AI coding agents to accelerate development while reviewing and productionizing agent-written code
 * Partner across engineering teams to build the foundational systems other products depend on

Highlights

Mission-Critical Payments - Build systems responsible for processing real-world transactions where correctness and reliability are essential

Own the Transactional Core - Solve challenging problems around idempotency, race conditions, retries, reconciliation, and distributed systems

Deep PostgreSQL Engineering - Work hands-on with query optimization, indexing, replicas, caching, and high-write workloads

Own Observability - Build the Datadog infrastructure engineers rely on to understand production behavior and performance

Architectural Ownership - Establish technical patterns and standards that other engineering teams build on
