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)
