📋 Description

• We’re looking for a Backend Research Engineer who’s passionate about building scalable systems and solving hard problems in ambiguous environments. • In this role, you’ll design and implement the distributed infrastructure that powers our core engine. • You’ll work across services written in TypeScript and Kotlin (no worries if you haven’t used these languages—we care more about your fundamentals and your willingness to learn), and deploy everything 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 fault-tolerant systems, scaling distributed architectures, or debugging hairy production issues. • If you like being at the intersection of deep tech and real-world impact, you’ll feel right at home. • We don’t use 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.

🎯 Requirements

• Experience building and operating scalable, distributed systems • Comfort working in a fast-moving, early-stage environment • Strong problem-solving skills and the ability to work with incomplete information • Familiarity with AWS or similar cloud platforms • You have deep experience designing and optimizing relational databases (we use Postgres), and you know how to structure data for both performance and clarity. • You’re comfortable working with infrastructure as code (e.g., Terraform or CDK) and see infra as part of the engineering system—not something separate from it. • Eager to learn new tools, languages, and technologies as needed • A thoughtful communicator who values clarity and simplicity • Comfort working in a fast-paced, early-stage startup environment • Bonus Points: Experience with event-driven architectures, message queues, or async workflows. • 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 developer tooling or security products.

🏖️ 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, working alongside an amazing team and some of the world’s experts to shape how AI transforms cybersecurity.
