DevX Engineer

Zealot helps public sector organizations strengthen their security posture through advanced defensive cybersecurity research, cyber threat intelligence, and intelligence analysis, enabling them to better understand, anticipate, and respond to emerging security threats.

We put AI at the centre of cyber operations, building offensive cyber capabilities in support of Western democracies. As our DevX Engineer, you will be part of the engineering team building the tools, automation and infrastructure that let our engineers and researchers move faster without sacrificing reliability or security.

The role

This is a hands-on combination of software engineering and DevOps. You will write production code, own infrastructure and improve the path from an idea to a reliable deployment. We are looking for someone who has built inside a cybersecurity company and understands the technical demands of that environment.

What you will do

• Build internal developer tools, services and automation that remove repetitive work and engineering bottlenecks.
• Improve development environments, build systems, automated testing and CI/CD pipelines.
• Build and operate the infrastructure used by software engineers, AI engineers and security researchers.
• Improve deployment reliability, observability, access management and incident debugging.
• Make research workflows reproducible and help turn experimental work into dependable systems.
• Work directly with the team to identify problems, prioritise fixes and own delivery end to end.

What we are looking for

• Experience working at a cybersecurity company in a hands-on engineering role.
• Strong software engineering skills: you can design, write, test and maintain production code, not just configure existing tools.
• Practical DevOps or platform engineering experience, including CI/CD, Linux, containers and infrastructure automation.
• Experience owning infrastructure and debugging problems across code, environments and deployment systems.
• Good judgement about speed, security, reliability and maintainability.
• Initiative, clear communication and the ability to take an ambiguous problem through to a working solution.

A strong advantage

• Technical service in Unit 8200 is a significant advantage, particularly in software engineering, infrastructure or cybersecurity. It is not a requirement.
• Experience at a cybersecurity startup, especially building internal platforms or tooling for security research teams.
• Experience supporting AI workloads, distributed systems or reproducible research environments.

Location

Full-time, based with our team in Tel Aviv, with the option to relocate to London. Openness to relocation is welcome but is not a condition of applying.

Why Zealot

Own systems the entire team depends on, work closely with engineers and researchers across AI and cybersecurity, and see your work directly improve how quickly we can build and deploy real capabilities.
