• Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming (where relevant).
• Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
• Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
• A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.

Preferred / Bonus:

• Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
• Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
• Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
• Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.

What we offer

• A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.
• A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.
• Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect).
• Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision.
• A purpose-driven mission: building software that’s reliable, accessible, and user-centered — making a real difference for people.

About Us

Launched in July 2020, the Kerv Group is a next-generation customer-first, cloud-first provider, created to help customers achieve successful business outcomes in a new digital era. We are undergoing an exciting period of transformation and growth following the acquisition of seven highly successful organisations, and we are now over 900 employees.

About the Role

As a result of growth in a new area of business, we are looking for an operationally focused individual to take ownership of our production and development AWS of infrastructure.

We currently host software for our own products, as well as custom software for 30+ customers across five AWS tenants and one Azure tenant. These environments support a range of applications and customers, from SMEs to large public-sector organisations, some of whom require CIS-compliant infrastructure. 

This role is the first step in creating a more mature infrastructure management capability. This role is a combination of hands-on cloud operations, security remediation, change control, automation and cost optimisation. 

Your part to play

You will help run and improve our AWS environments across production and development, with a strong focus on security, stability, compliance and cost control. 

Working with our existing security tooling, including OX Security and Wiz, you will identify and prioritise vulnerabilities, drive remediation activity, and maintain a forward plan to reduce risk and improve the security posture of our customer and internal environments. This includes owning patching and security updates across the estate, ensuring critical and high vulnerabilities are addressed within agreed timescales in line with Cyber Essentials and our customer obligations. 

You will work within our change control process, making sure infrastructure changes are properly assessed, documented, scheduled and communicated. You will also look for opportunities to automate repeatable operational tasks, improve consistency, reduce manual effort and support ongoing cost optimisation across our cloud estate. 

As part of a small team, you will work closely with engineering, service and product colleagues to keep our platforms secure, resilient and efficient. You will also support the Service Desk with escalations where needed. 

You will also: 
• Manage the day-to-day operation of AWS and Azure environments across multiple customer and internal estates. 
• Plan and deliver patching, system updates and infrastructure changes. 
• Use OX Security, Wiz and other tools to identify, triage and track vulnerabilities through to resolution. 
• Maintain a prioritised programme of work covering remediation, technical debt and broader security improvements. 
• Contribute technical input into change control, including impact assessments, implementation plans, rollback plans and scheduling. 
• Maintain and improve CIS-aligned configurations and controls where required. 
• Drive cost optimisation initiatives across AWS, including usage reviews, rightsizing and reducing waste. 
• Improve operational efficiency through automation, scripting and better tooling. 
• Support incident resolution, root cause analysis, documentation and continuous improvement. 

 All about You

You must have: 
• Hands-on experience supporting cloud infrastructure in live production environments, with strong experience in AWS and working knowledge of the other. 
• Experience of day-to-day infrastructure operations, including patching, vulnerability remediation and implementing production changes. 
• Experience working within a controlled change process in a production environment. 
• A solid understanding of cloud security fundamentals, including identity and access management, networking, platform hardening and general security best practice. 
• Experience using automation or scripting to reduce manual effort and improve operational consistency. 
• Strong organisational, troubleshooting and communication skills, with the ability to prioritise work and see actions through to completion. 
• Awareness of security and compliance requirements such as Cyber Essentials, CIS or similar good practice.

 Ideally you will also have: 
• Experience across both AWS and Azure. 
• Experience with OX Security, Wiz, or similar cloud security and posture management tooling. 
• Experience supporting multi-customer or multi-tenant environments. 
• Experience with Infrastructure as Code or configuration and deployment tooling such as Terraform, Ansible, Jenkins, PowerShell, Bash or Python. 
• Experience supporting public-sector or other regulated environments. 
• Experience identifying and delivering cloud cost optimisation initiatives. 
• Experience supporting operational escalations or working closely with a Service Desk. 
• Relevant certifications such as AWS, Azure, security or ITIL qualifications.
