The main focus will be building security controls into our engineering platform and developer workflows.You'll work across areas such as secure autonomous agent execution, CI/CD and code security, production access controls and software supply chain security. \nWe're looking for someone who can understand a security problem, work out practical controls, prototype and implement solutions, and work with software engineers where larger application changes are needed. \nKey responsibilities \nDesign, evaluate and implement controls for secure autonomous agent execution, including policy enforcement, permissions, sandboxing, execution isolation and auditability. \nEvaluate and implement ways to detect vulnerable or unsafe code changes before merge, integrating security controls into CI/CD and pull request workflows. \nExplore both existing security tooling and AI-assisted approaches to code security, considering accuracy, false positives, bypasses and usability. \nStrengthen production access by implementing secure privileged-access controls, controlled access paths, least privilege, session controls and auditability. \nAdapt engineering tooling and workflows where needed to support safer production access. \nStrengthen CI/CD and software supply chain security, including secure builds, dependency and container scanning, provenance, artefact signing, SBOMs and policy enforcement. \nBuild security automation and platform controls that are practical for engineering teams to use and maintain. \nWork directly with Form3 engineers on technical design, prototyping and implementation. \nContribute to wider security engineering work where your experience is useful, working with Form3 security specialists where deeper domain knowledge is needed. \nProduce clear technical documentation and handover material. \nDeliver changes using structured, low-risk practices while maintaining service availability.\nWE’RE LOOKING FOR \nEssential \nStrong hands-on experience in Platform Engineering, DevOps, SRE, DevSecOps or Platform Security, with good security fundamentals. \nExperience implementing security controls yourself, rather than only reviewing systems or reporting security findings. \nStrong understanding of CI/CD and modern software delivery, including integrating security controls into engineering workflows. \nGood understanding of software supply chain security, such as dependency security, secure builds, provenance, signing or vulnerability management. \nGood understanding of IAM, RBAC and least privilege. \nExperience with container security and some practical Kubernetes knowledge. \nComfortable writing automation or tooling in a programming language. Experience with Go or Python would be useful, with willingness to work in Go where needed. \nExperience working with engineers to deliver practical security improvements into production systems. \nGood communication and documentation skills. \nDesirable \nTerraform or other Infrastructure as Code experience. \nExperience with AWS, GCP or other public cloud platforms. \nSecurity automation or policy-as-code experience. \nExperience with container/runtime isolation or sandboxing. \nExperience securing AI agents or other AI-enabled engineering tools. \nExperience using LLMs for security analysis or automation. \nThreat modelling experience. \nKnowledge of mTLS, PKI, cryptography or key management. \nExperience in regulated, financial or other business-critical environments.\nTECH STACK \nGo / Python - security tooling and automation \nCI/CD - secure builds, automated security checks and engineering workflows \nKubernetes - containerised workloads and runtime security \nTerraform - Infrastructure as Code and security automation \nAWS / GCP - cloud infrastructure \nIAM / RBAC - least privilege and privileged access controls \nSoftware supply chain security - scanning, provenance, signing, SBOMs and integrity controls \nSecurity policy and automation - policy enforcement, guardrails and automated controls \nAI security - secure agent execution, AI-assisted analysis and engineering controls \nINTERVIEW PROCESS \nStage 1: Screening Call with Talent Team \nStage 2: Platform Security & Secure Engineering Practices interview \nWe always aim to stick to the above process, however there may be occasions when an additional interview stage is needed for us to be sure we’re hiring the right fit for the role. \nHIRING LOCATIONS \nHere are the locations that we are looking to engage with contractors from.
