Software Engineer - Platform / Core Infrastructure - Americas

XBOW is a company focused on building the future of offensive security through AI technology. They are seeking a Software Engineer - Platform / Core Infrastructure to design and implement scalable systems that power their core AI engine and distributed analysis systems.

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

Requirements:

• 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
• 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
