As a Senior Software Engineer, you’ll have the opportunity to build meaningful software, leverage cutting‑edge tools including AI, and work alongside a collaborative team that values creativity, autonomy, and continuous growth.

• Design, build, and maintain reliable microservices within a large-scale distributed architecture using Go for backend APIs and Angular for frontend applications.
• Develop and maintain RESTful APIs with OpenAPI/Swagger specifications, ensuring robust service-to-service communication and integration.
• Build scalable Angular UI applications and contribute to shared component libraries that support high-quality, consistent user experiences across the platform.
• Work within a microservices ecosystem where each service is independently deployable, using Kubernetes/Helm for orchestration and deployment.
• Implement comprehensive testing strategies using Ginkgo for Go services (unit, integration, smoke tests) and Jest/Cypress for Angular applications.
• Take ownership of complex technical challenges across the full stack, making architectural decisions that span multiple microservices, and contribute to the full software lifecycle — from sprint planning and ticket refinement to implementation, peer reviews, and demos.
• Drive technical initiatives and influence technical direction across the platform, evaluating tradeoffs and introducing improvements that benefit multiple teams.
• Use AI as a force multiplier. Experiment with LLMs, agentic tools, and AI‑integrated features to accelerate development, streamline workflows, and create smarter user experiences.
• Embrace change as a catalyst for continuous improvement and team efficiency.
• Work closely with product managers, designers, QA engineers, and other developers to build intuitive features that meet user needs and align with our mission.
• Lead and mentor junior and mid‑level engineers through thoughtful code reviews, knowledge sharing, and technical guidance. Model best practices and contribute to a collaborative, inclusive engineering culture.

• 3+ years of full-stack software development experience, including work on production systems.
• Strong experience with Go for backend development, including building RESTful APIs and microservices.
• Proficiency with Angular (preferably Angular 15+) and TypeScript for frontend development.
• Solid understanding of microservices architecture, including service discovery, inter-service communication, and distributed system patterns.
• Experience with REST API design and OpenAPI/Swagger specifications.
• Experience with MySQL in production environments, including schema design and query optimization.
• Hands‑on experience with containerization (Docker) and orchestration (Kubernetes/Helm).
• Familiarity with CI/CD pipelines and modern deployment practices in Kubernetes environments.
• Experience with comprehensive testing frameworks (unit, integration, and e2e testing).
• Comfortable working in AWS or similar cloud environments.
• Strong problem‑solving skills and ability to evaluate tradeoffs and make thoughtful implementation decisions that affect multiple services in a distributed system context.
• Enthusiastic about learning and leveraging AI tools to improve development efficiency and product capabilities.

• Bachelor’s degree in Computer Science or equivalent experience.
• Experience working in large-scale microservices environments (50+ services).
• Track record of driving technical initiatives or improvements across teams.
• Experience mentoring junior and mid‑level engineers and helping them grow their skills.
• Experience with system design and making technical decisions in complex distributed environments.
• Ability to evaluate and introduce new technologies, patterns, and tools to improve the development stack.
• Familiarity with Ginkgo testing framework for Go or Jest/Cypress for Angular applications.
