What makes hx different is the people who build it. Here, impact isn’t tied to title or tenure; it’s defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you’ll do the best, hardest work of your life in a company engineered to endure.

If that sounds like you, join us in building what comes next.

About The Security Function The Security function's mission is to safeguard the integrity, confidentiality, and availability of our customers’ data and hx Renew’s systems. By fostering a culture of vigilance, risk mitigation, and continuous improvement, we maintain the highest standards of security excellence.

Security at hx underpins every product and every customer interaction. As we scale our multi-product platform globally, the team ensures that innovation and growth are matched with rigorous security practices. We design controls, shape culture, and guide decisions that protect our business, our customers, and the wider industry.

As a Staff Security Engineer , you’ll play a pivotal role in building hx’s security function from the ground up. You’ll drive technical direction, design systems that are secure by design, and collaborate across engineering and product teams to embed security early in every decision. This role combines technical depth, influence, and cross-functional leadership to make security an enabler of growth and a differentiator for hx in the market.

What You’ll Be Doing

• Build hx's security programme from the ground up, setting direction for security architecture, compliance, and incident response as we scale globally.
• Design and implement security controls across AWS cloud infrastructure, Kubernetes workloads, and our multi-product platform, ensuring systems are secure by design.
• Integrate security into engineering workflows by embedding automated security testing, vulnerability management, and threat detection into CI/CD pipelines without slowing teams down.
• Lead or contribute to compliance initiatives (SOC2, ISO27001) by implementing technical controls and working cross-functionally with legal, engineering, and business teams to enable enterprise sales.
• Build security automation and tooling by writing code and scripts that scale security practices, detect vulnerabilities, and enforce policies efficiently.
• Partner with Engineering Managers, Principal Engineers, and Product Managers to embed security thinking early in design and architecture decisions.

What You’ll Need To Have Done

• Built or significantly contributed to security programmes from the ground up, establishing foundational security controls, compliance readiness, and incident response capabilities.
• Designed and implemented security architecture for cloud-based distributed systems (AWS or equivalent), including multi-account strategies, identity and access management, network security, and data protection.
• Driven technical security improvements by writing code, building tools, and implementing controls that scaled with company growth.
• Integrated security into development workflows through DevSecOps practices including automated testing, secrets management, container security, and infrastructure-as-code security.
• Led or supported compliance initiatives (SOC2, ISO27001, GDPR, or similar), mapping technical controls to compliance requirements and guiding teams through audit cycles.
• Evaluated security implications of AI/ML systems, including understanding AI-specific risks and implementing controls to secure them.

You’re unlikely to thrive here if

• You prefer narrow ownership of security tools over building cross-functional culture and influence.
• You view security as primarily compliance-driven rather than enabling business outcomes and customer trust.
• You lead through authority and mandates rather than influence, collaboration, and making engineers’ lives easier.
• You’re more comfortable writing policies than writing code, or can’t dive deep into complex systems to implement security controls.

If reading our Culture Document leaves you feeling neutral rather than energised, hx may not be the place where you’ll do your best work. We’re building something that asks for commitment and conviction, and we want you to feel excited by the opportunity to grow with us.
