• You'll be **engineer #4** on the founding team, working directly with our CTO and the other founding engineers. You'll ship features to production daily and own entire product areas from concept to deployment. • We're building fully agentic systems that automate complex workflows. It's technically challenging, fast-paced, and high-impact.

• Develop and maintain new dashboards and APIs • Implement new features and ensure continuous improvement of the platform • Ensure the quality, security, and performance of applications • Collaborate with Product and Data teams to create efficient and scalable solutions • Contribute technically to the team by guiding and mentoring more junior developers • Participate in architectural decisions and the technical planning of new features.

• Build upon and integrate customer feedback both internal and external into our API tooling and services. • Create new architectural foundations and mission critical distributed systems while collaborating with other teams. • Work within an agile scrum-based engineering team reporting to the Senior Manager of Core Services. • Uphold the highest levels of customer satisfaction in all things you do. • Advocate, create, and maintain API governance across engineering through collaboration, automation and outreach. • Own integrations within our API Gateway layer and API lifecycles from design to production. • Identify improvements to the design and implementation of various new and existing critical shared services. • Help to grow our infrastructure engineering organization's shared services relied upon by other engineering teams to accelerate product development.

• Design, build, and maintain internal tools and comprehensive frameworks supporting unit, integration, API, and UI testing using modern approaches with Jest, Locust, Flutter (iOS & Android) and Playwright • Implement containerized, reproducible test environments using Docker and CI/CD pipelines to support local and large-scale execution • Contribute to integration testing strategies for inter-service validation and shared dependencies • Architect and evolve the load, scale, and performance testing systems used to understand the limits of our system, verify system resilience and protect our critical user journeys • Build data-generation pipelines to create realistic workloads and performance test scenarios • Use APM tools (Datadog RUM, APM, DBM preferred) for build-over-build monitoring and troubleshooting • Evaluate and implement AI-driven tools for automated test generation and maintenance • Integrate self-healing, intelligent failure analysis, and test recommendations into CI pipelines • Partner with teams to adopt the tools and frameworks built by Test Infrastructure, with a shift-left strategy in mind • Champion best practices around metrics-based test infrastructure observability and monitoring • Mentor teammates on software architecture and design patterns
