Research Engineer / Software Engineer (Platform Infrastructure)
Overview
Build the future of offensive security with XBOW. Attackers are already using AI to move faster than defenders can react—we’re creating the platform that puts security ahead in the arms race.
Job Description
XBOW is applying cutting-edge AI to one of the world’s most urgent problems. Our AI-powered system autonomously discovers, validates, and even exploits vulnerabilities, giving organizations proof-backed results in hours instead of weeks.
Responsibilities
- - Design and implement infrastructure systems that scale reliably and securely, and can be deployed across multiple cloud environments (AWS, Azure, OCI etc.) and contexts (SaaS, on prem).
- - Tune and optimize cloud services across compute, storage, networking, and observability to drive performance, reliability and maintainability of core services.
- - Develop our core services, written in TypeScript, Kotlin and Go (and pick them up quickly if you haven’t used them before) to support our unique deployment and infrastructure requirements.
- - Support large-scale systems with event driven architectures.
- - 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
- - Partner closely with other engineers, AI researchers and Security researchers to enable high-quality, high-velocity product development
- - Design for resilience by implementing disaster recovery and business continuity strategies that ensure uptime, even when things break
- - Improve how we build, deploy, and monitor services at scale
Required Skills
- - Strong experience building and operating scalable, distributed systems on cloud infrastructure such as AWS or similar.
- - Comfortable working with infrastructure as code (e.g., Terraform, CDK) and see infra as part of the engineering system—not something separate from it.
- - A track record of performance tuning across cloud services, databases, and compute layers
- - Eager to learn new tools, languages, and technologies as needed
- - A thoughtful communicator who values clarity and simplicity and is comfortable working in a fast-paced startup and navigating ambiguity
- - Strong problem-solving skills and the ability to work with incomplete information
- - Curious, practical, and eager to work across layers of the stack when needed
- - You think proactively about failure modes and bring experience implementing disaster recovery and business continuity plans that keep critical systems running.
Benefits
- - 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.
