Role: Senior Software Engineer

We are looking for experienced Senior Software Engineers to help build and scale our platform. You will be involved in designing, developing, testing, and deploying robust and scalable software solutions. Our current technology stack includes Go, Typescript, Next.js, and Temporal running on Google Cloud Platform (GCP).

While experience with our specific stack is a plus, we strongly value solid engineering fundamentals, a pragmatic approach to problem-solving, and a willingness to learn. We are open to candidates with strong backend or full-stack experience in other modern languages and frameworks. Responsibilities include writing clean, maintainable, and testable code, participating in code reviews, collaborating closely with product managers, designers, and other engineers, contributing to architectural decisions, and mentoring junior engineers. The ideal candidate has significant experience building complex web applications, is comfortable working in a cloud-native environment, and is passionate about building high-quality products that solve real-world problems.
