Senior Platform Engineer, Quality Systems

Job Overview

We’re looking for a Senior Platform Engineer, Quality Systems to build the systems that make releases safe and fast. This is a platform engineering role with a clear mandate around release confidence and developer enablement. You’ll build test infrastructure and automated workflow validation for our core payment flows, and you’ll also own adjacent platform improvements in CI, pre-production environments, and release observability.

Key Responsibilities

• Build Release Confidence Systems: Design and implement automated smoke tests and workflow validations for our most important payment flows, and integrate them into CI and release gates


• Improve Environment Fidelity: Make testing and staging behave more like production by improving stability, data hygiene, environment health checks, and repeatable test scenarios


• Develop Test Infrastructure: Build frameworks and harnesses for API and event-driven workflow testing, including partner simulations and contract checks where appropriate


• Enable Developer Productivity: Build internal self-service tooling and automation that reduces manual steps, improves debugging workflows, and increases engineering velocity


• Improve Release Observability and Documentation: Strengthen release dashboards, visibility, and documentation practices to improve triage, bug tracking, and regression prevention over time


• Strengthen CI and Developer Workflows: Improve CI speed and signal, reduce flaky tests, and make failures easy to debug with useful artifacts and visibility


• Add Operational Guardrails: Partner with engineering to define monitors, canaries, rollout strategies, and rollback patterns for higher-risk changes


• Close the Loop on Regressions: Turn production regressions into durable prevention by adding automated checks, checklist steps, improved documentation, or better safety rails

Required Qualifications

5+ years of software engineering experience building and operating production systems

Demonstrated experience building test infrastructure, automation frameworks, CI gates, or developer productivity tooling

Strong foundation in systems engineering, debugging, and designing pragmatic solutions that improve reliability and velocity

Experience with distributed systems, asynchronous workflows, events, retries, and state transitions

Bachelor's degree in Computer Science, Engineering, or related field required

Technical Skills

Software Engineering: Strong coding ability in Python or another backend language (we use Python 3)

Test Engineering: Experience building workflow and integration tests beyond unit tests, including harnesses, fixtures, and test data strategies

CI and Tooling: Experience improving CI pipelines, reducing flakiness, and increasing the signal of automated checks

Cloud Infrastructure: Google Cloud Platform, or similar cloud platforms

Observability: Logs, metrics, tracing, dashboards, alerting, and using observability to improve release safety
