Software Development Engineer in Test

About the role

Onebrief is seeking a Software Development Engineer in Test to join the Quality Engineering team in shaping how quality is defined and delivered across the organization. In this role, you will partner with cross-functional teams to enhance release integrity, drive automation-first initiatives, and establish quality metrics and standards that raise the bar for how software is built, tested, and delivered. You will think beyond traditional testing, focusing on CI/CD quality improvements, internal tooling, performance testing, and enablement initiatives that empower teams to move faster with confidence in high-consequence environments. The ideal candidate brings a systems-level mindset and a passion for measuring and improving quality through pragmatic solutions and automation, challenging the status quo and innovating in how we release and validate our product. You will play an important role in shaping how we build, test, and deliver products that matter in defense and mission-critical contexts.

Key facts

What you'll do

As a Software Developer in Test, you will play a key role in shaping how we measure, improve, and scale quality across the organization. You will partner closely with Quality Engineering, SRE, Customer Relations and Product to strengthen release integrity, improve observability around quality health, and build the internal tools and frameworks that make high-quality delivery repeatable and efficient.

• Implement strategies that improve release integrity, from automation in CI/CD pipelines to validation processes that increase confidence in deployments.
• Instrument quality health metrics and dashboards that give teams clear visibility into product stability, release readiness, and test effectiveness.
• Drive internal tooling initiatives that improve the developer experience and enable teams to test, measure, and ship with higher confidence.
• Partner across engineering, infrastructure, and product to identify opportunities for system-level quality improvements and advocate for automation-first approaches.
• Use data and experimentation to continuously refine our approach to quality and ensure we are focusing on the most impactful areas.
• Work with fellow engineers to develop first-class quality measures that align with overall quality strategy, with a focus on monitoring and observability.
• Collaborate with Customer Relations and operational teams to translate real-world feedback into test coverage and quality improvements.
• Support performance testing and validation efforts that ensure software behaves reliably under demanding conditions.

Requirements

You are an experienced software engineer who brings both technical depth and a strong sense of ownership to how software is tested and released. You take pride in building systems that make quality measurable, scalable, and reliable. You collaborate closely with engineers and designers to create patterns and practices that help teams ship high-quality software with confidence. You are thoughtful, analytical, and disciplined in your approach, but also creative in how you identify opportunities to improve release integrity, automation, and performance. You are comfortable driving change, influencing best practices, and communicating effectively across teams. We work in the defense space, so we are looking for someone who is motivated by our mission and eager to contribute in a high-trust, fast-moving environment where everyone has a voice. As a member of our growing Quality team, you will play an important role in shaping how we build, test, and deliver products that matter.

• Understanding of modern quality engineering best practices, with the judgment to know when to apply or adapt them pragmatically.
• Strong technical foundation in release management, automation frameworks, and CI/CD systems, with experience improving release reliability through data-driven quality initiatives.
• 2+ years of experience building and maintaining test automation at multiple layers (integration, end-to-end) for complex applications, using modern languages such as C++/C#, GD Script, or Python.
• Proven experience using shift-left quality practices that improve code quality and development velocity through unit, integration, and static analysis.
• Experience building and maintaining internal testing platforms, test data management strategies, and test infrastructure as code.
• Strong ability to define and track quality metrics, including release health indicators, defect trends, and test effectiveness across the development lifecycle.
• Comfortable working in a fast-paced, ambiguous environment while maintaining a bias for action and clear communication.
• Willingness to engage directly with customers and stakeholders to understand quality challenges and validate solutions in operational contexts.
