We're looking for a senior backend engineer who builds reliability through elegant, production-ready code architecture. You'll have significant authority to rearchitect critical systems, replacing homegrown solutions with industry-standard tooling and patterns that handle 10k+ req/sec at scale.
This is primarily a programming role focused on building robust, observable systems through code. You'll spend most of your time architecting and implementing reliability improvements, not managing infrastructure.
What makes this role unique:
- Architectural Authority: Drive decisions on adopting technologies like Temporal.io for durable execution vs. maintaining custom retry logic
- Production Scale: Design systems that handle high-throughput payment and loyalty processing with strict SLA requirements
- Code-First Reliability: Improve system reliability by writing better application code, not just adding monitoring
- Industry Standards Over NIH: Replace internal implementations with proven, production-ready solutions
- Rearchitect core reliability patterns: Replace custom retry mechanisms with durable execution engines like Temporal.io
- Implement robust event processing: Migrate direct webhook handling to reliable delivery systems like Hookdeck with proper delivery semantics
- Build behavioral monitoring: Integrate time-series databases to detect and alert on changing system behavioral patterns
- Eliminate technical debt: Systematically replace "not invented here" solutions with industry-standard, battle-tested alternatives
- Design and implement systems that maintain performance and reliability at 10k+ requests/second
- Write production-grade code for payment processing, wallet operations, and loyalty program mechanics
- Build comprehensive error handling, circuit breakers, and graceful degradation patterns
- Implement distributed system patterns for fault tolerance and observability
- Instrument deep observability into application code using existing frameworks (Datadog)
- Design monitoring that provides actionable insights into system behavior and business metrics
- Build alerting that proactively identifies reliability issues before they impact users
- Lead incident response with focus on permanent architectural fixes rather than band-aid solutions
- Evaluate and recommend new technologies and architectural patterns for production readiness
- Collaborate with product engineering teams to embed reliability patterns into new feature development
- Drive technical decisions around system architecture, scaling, and reliability patterns
- Mentor engineers on production best practices and reliable system design
- 5+ years backend engineering experience building high-throughput, production systems (10k+ req/sec)
- Strong programming skills in modern languages - our stack uses TypeScript, but we value polyglot engineers
- Production architecture experience with distributed systems, microservices, and reliability patterns
- Systems thinking: Ability to identify when to build vs. buy vs. adopt existing solutions
- Cloud-native development with AWS services (ECS, RDS, ELB) and modern deployment patterns
- Technical leadership: Experience making architectural decisions and driving technical improvements independently
- Experience with durable execution systems (Temporal.io, Step Functions, etc.)
- Background in fintech, payments, or high-reliability systems
- Knowledge of event-driven architectures and reliable message processing
- Experience with time-series databases and behavioral analytics
- Track record replacing legacy systems with modern, scalable alternatives
- Startup or high-growth experience where you've scaled systems through rapid growth
- Traditional "infrastructure-first" SRE background
- Focus on Kubernetes administration or infrastructure provisioning
- Scripting-heavy operational work
- Basic monitoring setup (connecting Datadog to ECS is table stakes, not the role)
- Backend: TypeScript/Node.js, REST APIs, high-throughput transaction processing
- Infrastructure: AWS (ECS, RDS, ELB), Cloudflare
- Observability: Datadog (existing), custom instrumentation and analytics
- Scale: 10k+ requests/second, real-time payment and loyalty processing
- Architecture: Distributed microservices, event-driven systems
- Identifying and replacing fragile custom implementations with industry-standard solutions
- Architecting reliable event processing where current approaches show brittleness
- Building proactive monitoring for behavioral changes that current systems miss
- Designing fault-tolerant patterns for high-throughput transaction processing
- Evaluating and implementing durable execution patterns for complex workflow reliability
- Creating robust delivery semantics for webhook and event-driven architectures
- Robust health benefits packages (1 of 4 medical plans cost $0 for full family coverage)
- Company contributed 401k plan
- An empathetic team that values mental wellness and work/life balance
- A brand new NYC office!
- Ground floor opportunity to bring a product to market that helps people in a way that doesn't exist today
