Sr. Software Engineer, Testing

About Technology at Bridgewater

The Technology team at Bridgewater engineers systems to understand the world. These systems synthesize and industrialize our global understanding into a hive mind of macroeconomic knowledge which enables us to educate and collaborate with the world’s most influential central banks and policy makers and carefully and strategically manage the world’s most important capital. Our technologists are engineering highly available, high performing and highly secure cloud platforms and infrastructure which support and scale our investing operations.

The goal of the Portfolio and Trading teams is to translate our understanding of how the global economy works into strategy specific portfolios and execute those investment decisions with maximum precision, efficiency, and reliability.

Working alongside the Portfolio team is a uniquely talented technology group that builds and manages the platforms that allow our portfolio strategists, investors, and operations teams to create and test new portfolio strategies and logic, construct portfolios, and manifest our desired portfolios to securities we can trade in the markets.

Working alongside our Trading team are technologists who design, build, and maintain the systems that power execution, data flow, and real‑time decision‑making across global markets. They work closely with investors and traders to optimize performance, automate processes, and ensure the firm’s strategies are implemented with speed, accuracy, and resilience.

We are hiring for this role into both the Portfolio and Trading teams. The Sr. SWE, Testing will design and build advanced test automation platforms that support high‑performance, mission‑critical systems. This role will be instrumental in reducing reliance on external vendors and enabling faster, more reliable development cycles through scalable automation and AI‑driven testing approaches.

This position sits at the intersection of software engineering, testing strategy, and platform architecture, with a strong emphasis on enabling agentic development loops and minimizing latency and downtime in production systems.

Ultimately, if successful in this role, you will reduce testing cycle times and faster release velocity, increase system reliability with fewer production incidents, adopt scalable automation platforms across teams, and effectively validate performance and business logic.

• Design, build, and maintain scalable test automation platforms for complex systems
• Develop diagnostic and validation tools across both production and QA environments
• Enable end‑to‑end automated testing for business logic and system performance
• Support agentic/AI‑driven testing workflows to accelerate development cycles
• Collaborate with engineering teams to integrate testing into the SDLC
• Improve system reliability by reducing testing time and preventing production issues
• Contribute to the evolution of testing strategy during platform re‑architecture (e.g., OMS SaaS migration)

• Strong computer science fundamentals with 4+ total years of experience in technically rigorous environments holding extremely high bars for their engineers
• 2+ years of experience in SDET or test architecture roles with an emphasis on true software engineering
• Ability to design diagnostic tools and testing infrastructure
• Strong problem‑solving and system design skills
  
  Exposure to agentic systems or autonomous testing frameworks
• Familiarity with low‑latency systems and performance optimization

• Proven experience building complex test automation platforms from scratch
• Background with OMS (Order Management Systems) or similar platforms
• Strong understanding of software testing methodologies and frameworks
• Experience with distributed systems, data platforms, or financial systems
• Experience integrating AI/ML tools into testing workflows
• Experience in financial services, especially trading or portfolio systems

The anticipated onsite requirement for this role is two days per week (Tuesday and Wednesday) at our Westport, CT campus.
