Senior Platform Engineer, Quality Systems

Location: Remote (US)

Type: Full-time

Experience: 5+ years

About Astra

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.

The Role

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.

What You'll Do

• 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

What We're Looking For

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

Why This Role Matters

• 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

What We Offer

• 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

Remote Work and Culture

Astra is a remote-first company hiring only within the U.S. We value thoughtful collaboration, clarity, and initiative. We're proud to be an equal opportunity employer and are committed to building a diverse and inclusive team.

How to Apply

We're looking for engineers who enjoy building high-leverage systems that improve reliability and velocity. If you're excited to own release confidence through tooling, automation, and platform improvements, we'd love to hear from you.
