About Adzuna

Adzuna is a job search engine that lists every job, everywhere. From our launch in the UK in 2011, we now have tens of millions of visitors a month and are busy conquering the world from our HQ in West London alongside our remote teams - helping millions of people find better, more fulfilling jobs. We already have a suite of AI-powered tools (such as ValueMyCV, Prepper and ApplyIQ) built by our talented team and their passion for building new AI-powered tech for job seekers. We're a commercially minded team that moves fast, takes ownership and loves what we do.

About the Role

This is a fantastic opportunity for a commercially-minded, high-impact Infrastructure Engineer to join our fast-moving team. In this pivotal role, you will be responsible for architecting and managing our containerized environments, focusing on Kubernetes orchestration and cloud infrastructure. You will work closely with our engineering teams to ensure scalable, reliable, and secure deployment pipelines, driving the transition towards a modern, container-first infrastructure.

We're building a container-first platform on AWS EKS, and we're still running an older estate on EC2 instances (Perl services and Chef-managed machine images). Both are managed with Terraform. Expect roughly one third of your time on the Kubernetes platform and two thirds on migrating services off the older estate. In your first year, that means moving the job ingestion and search services onto Kubernetes and switching off the last Chef-managed machine images. If you find that kind of archaeology satisfying, you'll enjoy this role a lot more than someone who only wants greenfield.

What You'll Do

• Bridge cloud infrastructure and business needs, translating requirements into technical answers, and flagging roadblocks before they become surprises.
• Write Terraform to manage AWS resources.
• You'll write code to eliminate manual, repetitive work, extending existing services with plugins where appropriate. "Automate yourself" is a core engineering principle here.
• Own the deployment, scaling, and day-to-day management of our Kubernetes clusters using ArgoCD and Helm.
• Design and maintain the CI/CD pipelines that get our microservices into production.
• Build monitoring and logging for new services, and work with the stack we already run: Prometheus, Grafana, Elasticsearch, and AWS CloudWatch.
• Ensure high uptime across all of our services, work on reducing & optimising cloud costs
• Partner with the engineering team to speed up the development cycle on our primary stack, and help retire what's left of the legacy one.
• Keep things consistent, and reach for the clean, simple solution over the clever one.

Tech Stack Includes

• Languages & Frameworks: Perl, Python, Terraform, Chef
• Frontend: React, HTML, CSS (Tailwind)
• AWS Ecosystem: EC2, S3, EKS, Lambda, RDS, Athena, Kinesis, SES
• Databases & Search: PostgreSQL, MySQL, SOLR
• Monitoring: Grafana, Prometheus, ElasticSearch

While we look out for all of these skills, we do not expect experience in all of them. We value a strong foundation in core programming principles and a genuine eagerness to learn.

Requirements

Must have

• 5+ years working as an Infrastructure, DevOps, Platform, or SRE Engineer.
• A knack for consistency and simplicity.
• The ability to work autonomously while communicating clearly and efficiently with a highly distributed team.
• Solid working knowledge of AWS and Kubernetes.
• Fluency in scripting (Python, Bash) and CI/CD tooling to automate infrastructure and deployment.
• Strong grounding in cloud networking, security practices, and identity management (IAM).
• The judgement to architect complex systems and act alongside the existing platform engineers.
• A habit of documenting things well enough that a teammate (or you six months later) can work out what's going on.
• A strong commercial / ROI mentality and focus on business outcomes

Nice to have experience

You've done some of these:

• Built and configured machine images with Packer and Chef.
• Run workloads on Kubernetes: EKS, ArgoCD, and the debugging that comes with them.
• Configured and debugged Nginx, Apache, or Varnish under real traffic.
• Administered MySQL, PostgreSQL, or Elasticsearch in production.
• Developed a solid grasp of what actually drives email deliverability.
• Optimized a cloud bill.
• Caused a service outage, and then fixed it.
• Owned a mistake, and then shipped the technical or organizational change that stopped it recurring.
• Experience using agentic AI for infrastructure-as-code and/or software development

Benefits

• Reward: Our package which includes a competitive salary and stock options (we are all owners!).
• Wellbeing: Amongst other things, enhanced maternity and paternity leave; 25 days paid holiday per year plus 8 bank holidays; 3 paid volunteer days/year; Summer hours through July and August (we finish at 4pm on a Friday); and a full programme of wellbeing activities and events.
• Hybrid working: We are a fully hybrid company - half our workforce is remote. With employees located in different time zones, we embrace asynchronous work and ensure that everything we do reflects the hybrid nature of our workforce so that everyone feels included. In addition, we have a travel programme, to help facilitate effective hybrid working.
• Diversity & inclusion: We are committed to hiring a diverse workforce and creating an environment where everyone feels included and welcome. Our D&I committee helps deliver a programme of activities and actions to support this important area.
• Training: Learning and development is an important pillar of our culture and there are plenty of opportunities to learn, develop and grow whether through our Adzuna Academy training programme, attending conferences, team training budgets, individual development plans and coaching from experienced and supportive peers and managers.
• Fun stuff: We have a packed social calendar, twice yearly global team get-togethers and an enviable culture thanks to the amazing and smart people who make Adzuna a great place to work. Lots of this is done virtually to ensure that everyone is included.
