Location: Remote (US)
Type: Full-time
Experience: 5+ years
Astra is a high-impact engineering team building mission-critical financial infrastructure. Our fintech platform powers payment processing, fraud detection, and financial compliance for businesses handling 100M+ in weekly transaction volume. We maintain 99.9%+ uptime, process complex cross-border payments, and coordinate with multiple third-party financial services while meeting strict regulatory requirements.
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.
This role requires strong systems thinking, hands-on engineering, and comfort working across distributed services and asynchronous workflows (webhooks, delayed processing, external dependencies). The goal is to help the team ship more frequently with higher confidence by building high-leverage tooling and automation that becomes part of our day-to-day engineering workflow.
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
Senior Platform Engineer, Quality Systems Requirements
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
Education
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
Preferred Experience
Fintech or High-Reliability Systems: Payments, money movement, reconciliation, risk, or compliance systems
Partner Integrations: Testing and operating systems dependent on external APIs and webhooks
Release Engineering: Building release gates, canaries, rollout plans, and rollback playbooks
Test Environment Strategy: Experience improving staging fidelity and maintaining stable test fixtures for complex systems
Direct Impact: You’ll be a big part of a small engineering team and your work will directly improve how we ship
High Leverage: The tooling and automation you build will compound over time as the product and team scale
Faster, Safer Releases: Help the team ship more frequently with smaller releases and higher confidence
Complex Problems: Work on sophisticated workflow and reliability challenges that few engineers get to solve
Team Enablement: Make it easier for engineers to build and validate changes without fear of unpredictable regressions
Competitive compensation with equity in a growing fintech company
Remote-first culture with flexible working arrangements
Small team, big impact - your work directly shapes our platform
Professional growth - lead technical decisions and drive foundational improvements
Modern tech stack - work with cutting-edge cloud technologies
Mission-driven - build systems that power financial innovation
