Backend Engineer, Senior and Staff

Build the backend services that turn noisy identity, device and
behavioral signals into trustworthy, explainable decisions for
banks, fintechs and government agencies. This is not a ticket
queue. You will own production paths where latency, correctness
and adversarial pressure all matter.

Performance Objectives

* Ship and own low-latency decisioning services that keep p99
response times inside agreed SLOs under peak identity and fraud
traffic
* Cut incident-causing defects in your services by designing for
failure: clear contracts, idempotency, backpressure and tested
rollback paths
* Turn ambiguous fraud and identity requirements into production
APIs and data contracts that product, risk and data science can
rely on without rework
* Drive technical decisions across team boundaries

Essential Qualifications

* Experience building and operating backend services in
production, including APIs, data stores and asynchronous
workflows.
* Significant hands-on coding experience with a solid
understanding of concurrency and multi-threading.
* Proven delivery of low-latency or high-throughput systems with
explicit SLOs, load testing and incident response.
* Experience architecting microservices and RESTful APIs,
including service contracts, schema evolution and integrations
with external data providers or internal ML signals.
* Use AI in your daily workflow to raise your impact and
efficiency
* High bar, owner mindset
