Software Development Engineer in Test

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination.

Military planning is complex by nature, requiring teams to coordinate information, people, and decisions across systems and locations. Onebrief brings planning, collaboration, simulation, and AI into one connected environment, helping teams test strategies, adapt to changing conditions, and make decisions with greater clarity when the stakes are real.

We are a distributed team of builders from military, operational, and technology backgrounds who care deeply about improving how important work gets done. Some team members work remotely, while others work directly alongside customers in operational environments around the world.

Founded in 2019, Onebrief is backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital. Valued at more than $2 billion, we continue to invest in product innovation, AI capabilities, and team growth.

We’re looking for a Software Developer in Test to partner with our Quality Engineering team in shaping how we define and deliver quality across the organization.

In this role, you’ll help enhance our release process and release integrity, software development to drive automation-first initiatives, and establish quality metrics and standards that raise the bar for how we build, test, and deliver software. You’ll 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.

We’re looking for someone with a systems-level mindset and a passion for measuring and improving quality through pragmatic solutions and automation, who isn’t afraid to challenge the status quo and innovate in how we release and validate our product.

You’re 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’re thoughtful, analytical, and disciplined in your approach, but also creative in how you identify opportunities to improve release integrity, automation, and performance. You’re comfortable driving change, influencing best practices, and communicating effectively across teams.

We work in the defense space, so we’re 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’ll play an important role in shaping how we build, test, and deliver products that matter.

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’ll 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.

• Instrumenting quality health metrics and dashboards that give teams clear visibility into product stability, release readiness, and test effectiveness.

• Driving internal tooling initiatives that improve the developer experience and enable teams to test, measure, and ship with higher confidence.

• Partnering across engineering, infrastructure, and product to identify opportunities for system-level quality improvements and advocate for automation-first approaches.

• Using data and experimentation to continuously refine our approach to quality and ensure we’re focusing on the most impactful areas.

• Working with your fellow engineers to develop first class quality measures that align with overall quality strategy, with a focus on monitoring and observability

Required:

• 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, deployment confidence, and developer velocity.

• Hands-on experience with performance, resilience, and security testing, including integration of those checks into CI/CD pipelines and observability systems.

• Experience building internal tools or developer utilities that enhance testability, observability, and overall release integrity.

• Strong understanding of API quality, including contract validation and dependency testing in distributed systems.

• Demonstrated ability to produce quality, ownership and best practices across teams.

• Solid collaboration and communication skills, with the ability to promote a culture of quality and continuous improvement.

Nice to haves:

• Experience maintaining or building declarative CI/CD pipelines (e.g., Azure Pipelines, GitHub Actions).

• Familiarity with visual regression testing, performance tooling (k6, JMeter, Artillery), or distributed system fault injection.

• Containerization and orchestration experience (Docker, Kubernetes).

• Familiarity with observability stacks like Grafana, Kibana, or Prometheus.

Most importantly, you are a true Onebriefer:

• You are obsessed with creating value for real users

• You are ambitious, scrappy, and a creative problem-solver

• You learn quickly, work iteratively, and naturally seek collaboration

• You approach your work with integrity, intellectual honesty, and a low ego

• You communicate frankly, clearly, and succinctly

• You thrive as a self-starter, embracing autonomy and ambiguity
