[Hiring] Software Engineer @XBOW

Role Description

We’re looking for a Software Engineer who’s passionate about building reliable and high-quality products with robust backend systems. In this role, you’ll design and implement end-to-end features across the stack: from React-based frontends and TypeScript APIs to backend services in Kotlin and Go, all deployed on AWS.

You’ll be joining a small team of superstars that’s shipping quickly and operating with high trust. This is a role for someone who loves to own open-ended problems and figure things out—whether that’s designing seamless API contracts, optimizing database interactions, or building scalable systems that make powerful AI capabilities accessible. If you like being at the intersection of deep tech and real-world impact, you’ll feel right at home.

What You'll Do

• Design and build full-stack systems that integrate frontend and backend seamlessly
• Develop scalable APIs and backend services in TypeScript, Kotlin, and Go
• Deploy and operate services in AWS and other cloud providers
• Own problems end-to-end—from design through deployment to production support
• Navigate ambiguity and help define how we build as much as what we build
• Collaborate closely with teammates across the stack, including AI researchers, Security researchers, and backend engineers

Qualifications

• Experience building and operating full-stack systems
• Proficiency with TypeScript
• Experience designing and consuming APIs (REST or GraphQL)
• Strong backend development experience (Node.js, Kotlin, Go, or similar languages)
• Strong problem-solving skills and the ability to work with incomplete information
• A thoughtful communicator who values clarity and simplicity
• Comfort working in a fast-paced, early-stage startup environment

Bonus If You Have

• Experience with event-driven architectures, message queues, or async workflows
• Experience building scrappy, iterative frontends where speed and feedback loops matter more than polish
• Familiarity with AWS or similar cloud platforms
• Comfort working with infrastructure as code (e.g., Terraform or CDK)
• A strong appreciation for user experience and design, even if you’re not a formal designer
• Comfortable prototyping quickly in React/TypeScript and turning ideas into working features fast
• Experience designing and optimizing relational databases (we use Postgres)
• Background in systems programming, networking, or performance tuning
• Experience with hybrid deployments (cloud + on-prem) and know how to build resilient systems that handle the complexity of mixed environments
• Experience working in an early-stage startup
• Prior experience building security products or products for technical users

Benefits

• Competitive salary and a generous equity package, making you a true owner of the company
• Shape your role, lead the function, and grow with the company as we redefine cybersecurity
• You will tackle technically complex challenges and play a pivotal role in the growth of our business

What Else You Should Know

• Location: Remote (all team members are remote but we meet regularly and you’re supported to travel to collaborate with colleagues in person)
• Contract: Full-time
• Hiring Process:
  • 45-min introductory chat with our Talent team
  • 45 minutes with one of our Engineering Leads
  • 2-3 hour technical deep dive around relevant case study
  • 30-min final meeting with the Engineering Lead for the assigned team
• We aren't focused on seniority titles at XBOW—so if you’re worried about “leveling,” don’t be. We care a lot more about mission fit, capability, and impact than what’s on your LinkedIn headline.
• We believe in people who are driven by curiosity and a willingness to learn. Even if you don't check every box, we encourage you to apply if you're excited about the role and our mission.
