We’re looking for a Software Engineer - Platform / Core Infrastructure who’s passionate about building scalable systems and solving hard problems in ambiguous environments. In this role, you’ll design and implement the complex distributed infrastructure that powers our core AI engine and distributed analysis systems, enabling XBOW to run seamlessly across multiple cloud providers (AWS, Azure, OCI etc.) and contexts (SaaS, on prem). This is a role for someone who sees infrastructure as a product, loves clean abstractions, and knows how to dig into performance issues across layers. You’ll join a high-trust, high-velocity team where your work will have an immediate impact on both developer experience and product performance. If you like being at the intersection of deep tech and real-world impact, you’ll feel right at home. ## What you will do
Essential:
Strong experience building and operating scalable, distributed systems on cloud infrastructure such as AWS or similar. - Extensive experience with Containerisation and Orchestration technologies (e.g. Docker and Kubernetes). - Comfortable working with infrastructure as code (e.g., Terraform, CDK) and see infra as part of the engineering system—not something separate from it. - Experience with event-driven architectures, message queues, or async workflows (for example, using Kafka). - 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. Advantageous:
Experience with deploying infrastructure to multiple environments (SaaS, on-prem) and know how to build resilient systems that handle the complexity of such environments. - Familiarity with modern observability practices (logs, metrics, tracing) and how to apply them
Experience working in an early stage startup
Prior experience building developer tooling or security products
Hands-on experience with OpenSearch or Elasticsearch at scale
Previous experience building platform teams or working on internal developer platforms
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 in the US or EMEA (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:
