Job Description
We are looking for a senior, hands-on software engineer with broad experience across software development, cloud infrastructure, DevOps, and developer tooling. You should be comfortable building production software while also improving the platforms, tools, and practices that enable other developers to work effectively.
Core Software Engineering
- 5+ years of professional software engineering experience, including experience designing, building, and operating production systems.
- Strong software development skills in one or more modern programming languages such as TypeScript/JavaScript, Python, or similar, with the ability to contribute to backend applications and services when required.
- Strong understanding of API design, distributed systems, authentication/authorization, databases, networking, and modern application architecture.
- Experience designing maintainable, reusable software components rather than solving problems only within a single application.
- Strong Git and software development fundamentals, including code review, testing, dependency management, release management, and debugging.
- Cloud & Platform Engineering
- Strong hands-on experience with AWS and designing, deploying, and operating cloud-native applications.
- Experience with containers and Kubernetes, including Docker, Kubernetes/EKS, Helm, ingress, configuration, secrets, scaling, and troubleshooting.

- Experience designing and maintaining shared platform capabilities that can be reused across multiple applications and development teams.
- Strong understanding of cloud networking, identity and access management, secrets management, observability, reliability, and production operations.
- Ability to evaluate infrastructure and application architectures for security, scalability, reliability, performance, and cost.
CI/CD & Developer Experience
- Strong experience designing and maintaining CI/CD pipelines, preferably using GitHub Actions or comparable tooling.
- Experience creating reusable build, test, deployment, and release workflows across multiple repositories or applications.
- Experience building developer tooling, application templates, reusable libraries, SDKs, CLIs, or internal platforms that reduce repetitive engineering work.
- Ability to identify recurring development and operational tasks and turn them into automation, self-service capabilities, and paved-road patterns.
- Strong understanding of developer experience and the ability to balance standardization and guardrails with developer flexibility.
- Security & Production Readiness
- Working knowledge of secure software development practices, including IAM, secrets, dependency management, application security, network security, and least-privilege access.
