Requirements
• Strong experience with building software around LLMs: prompting, agentic orchestration, fault-tolerance, and integration of LLM parts with hard-coded logic. • Strong software engineering skills: architecting and building production-grade software that runs reliably and can be maintained. • Experience with TypeScript or proven ability to learn a new programming language quickly. • Strong skills in structured and independently-driven problem-solving. Able to work with incomplete information and rapidly testing hypotheses. • Comfortable with an energetic environment that mixes the fast-paced agile prioritisation of a startup with the curiosity mentality of a research lab. • Eager to own projects and jump into the deep end, learning as you go. Curious, adaptable and collaborative. • MSc or equivalent or higher in computer science, math, physics or machine learning. • Prior experience with the security sector, especially involving offensive security and/or applying LLMs in a security context. • Contributions to open-source software, particularly within applications of or frameworks for LLMs. • Strong theoretical background, e.g. a Ph.D in machine learning, computer science or math. • Startup experience and comfort with ambiguity.
Responsibilities
• We’re looking for a Software Engineer with deep expertise in LLM prompting, orchestration, and software engineering. In this role, you’ll design and implement systems that coordinate large language models with real-world tasks, advancing the intelligence at the heart of our platform. You’ll collaborate with our AI, Engineering and Security teams to create novel prompting strategies, build orchestration layers, and deliver production-ready systems in TypeScript. • This role is for someone who thrives in a fast-moving, research-driven environment and enjoys turning ambiguous ideas into robust, scalable solutions. • Build LLM-powered software that actually works, by designing prompt flows and orchestrations that ensures great performance with no false positives. • Architect and build an AI-powered software stack that is production-grade, testable and maintainable. • Design and build experiments and evaluation frameworks for performance testing of the system at scale. Conduct data analysis to draw conclusions. • Collaborate with the rest of the AI team, with security experts, and both frontend and backend developers to create end-to-end systems that work and customers love. • Own projects end-to-end: from basic ideation and experimentation to deployment and production monitoring. • Continuously conduct research on how to harness the advancements in LLMs to make our system better and faster.
Benefits
• Compensation & Equity: Competitive salary and a generous equity package, making you a true owner of the company. • Career Growth: Shape your role, lead the function, and grow with the company as we redefine cybersecurity. • Meaningful Work: 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. • 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: • 1. 45-min introductory chat with our Talent team. • 2. 45 minutes with one of our Engineering Leads. • 3. 2-3 hour technical deep dive around relevant case study. • 4. 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.
