Accrue
Senior Reliability Engineer (Backend Focus)
NYC About our team
Accrue is a fintech company that powers modern customer loyalty at the payment layer. Centered around its branded stored value wallet solution, Accrue’s platform helps brands take control of their payments and refunds, reward customer loyalty, and bypass traditional payment giants. Build a deeper, more durable customer base while optimizing your bottom line – all with Accrue. About the Role
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 What you'll do
System Architecture & Reliability Engineering
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 Technical Leadership
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 What you'll need
Required
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 Highly Valued
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 What We're NOT Looking For
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 Types of Challenges You'd Tackle
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 Salary Information The range listed below is just one component of Accrue's total compensation package; This role will receive a competitive salary + benefits + equity. The salary range is for US-based employees located in the listed market. Other benefits include those listed above such as healthcare and 401k with 3% contribution. Salary Range $180,000 - $220,000 USD Accrue is an equal opportunity employer committed to fostering an inclusive, innovative environment.
