We’re looking for a Senior Software Engineer to help build and evolve a modern cybersecurity SaaS platform. This is a senior level role for engineers who want to grow building secure, scalable, and well-tested systems. We value those who understand that quality, reliability, and ownership are part of the job.

You’ll work on end-to-end features across the stack, collaborate closely with product, and contribute to a system that must perform reliably under real-world conditions. Our customers depend on our platform, which means engineering discipline, thoughtful design, and operational awareness are foundational to how we work.

This position is on a high-profile project, so you’ll be ramping up quickly, starting with authentication (bearer tokens and MFA). If you think in systems, enjoy and thrive in a collaborative environment, communicate clearly, and are motivated by building durable solutions then we’d love to meet you!

Responsibilities:

• Design and implement features across the stack (backend services, APIs, frontend), owning those features from implementation through production support

• Write clean, well-tested, maintainable code

• Contribute to technical design discussions and code reviews

• Debug issues across distributed systems and production environments

• Continuously improve code quality, automation, and engineering practices

Our general tech stack:

• Languages: Java, Python, Rust, Go, C#, TypeScript (JavaScript)

• Infrastructure: AWS (ECS, EKS, Fargate, Lambda, S3, RDS Aurora)

• Data: PostgreSQL

• Build/Deploy: GitHub Actions

• Platform Task Orchestration: Temporal

You’ll thrive here if you:

• Take ownership and follow through on commitments

• Care about code quality, performance, and testing

• Are comfortable learning new parts of the stack and enjoy learning and evolving technically, professionally, and personally

• Communicate clearly and collaborate well, valuing candor, care, respectful disagreement as a path to better outcomes

• Believe diverse perspectives make teams and products stronger

• Prefer disciplined execution over heroics

• Approach systems thinking with rigor, curiosity, and a bias toward root-cause understanding

• Take initiative and bias toward action; you look for ways to improve systems and move work forward

Minimum Qualifications:

• Bachelor’s degree in computer science, software engineering, or a related field

• Working proficiency in one or more languages from our stack and relational databases

• Strong problem-solving and communication skills

• Experience building or consuming RESTful APIs

• Familiarity with containerization and cloud-based architectures (Docker, AWS)

• Understand testing fundamentals (unit/integration)
