Platform Engineer
Location: Cambridge, UK
Join Our Visionary Team
OLI's growing organization is at the center of our mission to make complex chemistry computable, accessible, and actionable. Our teams build the scientific software and infrastructure that enable engineers across energy, water treatment, critical materials, and other industries to solve complex problems with confidence.
As more of OLI's products and customer experiences move to the cloud, the reliability and scalability of the infrastructure behind them become increasingly important. We are looking for a Platform Engineer to help build, operate, automate, and support the cloud foundation for OLI's next generation of products.
Your Role
As a Platform Engineer, you will be a hands-on member of the team responsible for OLI's cloud infrastructure. You will help build and support our Azure environment for OLI's next-generation platform.
This role is ideal for a mid-level engineer looking to grow. You'll work within established platform architecture and engineering standards to implement infrastructure as code, support CI/CD pipelines, monitor production systems, troubleshoot deployment and performance issues, and strengthen automation across our cloud environments. As you build experience, your ownership will grow with it, from taking on larger pieces of the platform and leading incident response to helping shape the standards you started out following.
You will collaborate closely with senior platform, software, and process systems engineers. This is a strong opportunity for an engineer who wants to deepen their cloud, DevOps, and reliability expertise while contributing directly to a customer-facing SaaS platform. We see platform work as software engineering: much of what you build will be code that other engineers depend on.
About OLI
OLI is the global standard for electrolyte chemistry simulation, with over 50 years of peer-reviewed science embedded in its platform. More than 500 enterprises and academic institutions across 35+ countries rely on OLI software to make confident, defensible engineering decisions - from predicting scale formation and modeling corrosion to optimizing water chemistry and complex industrial processes.
Why You're Vital to Our Mission
As client usage of OLI's cloud-based offerings grows, we need infrastructure that is reliable, secure, observable, and increasingly automated. Your work will help us strengthen the Azure foundation for our next-generation platform and reduce operational burden through better tooling and automation.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
By improving deployment reliability, infrastructure consistency, monitoring, and support, you will directly contribute to customer experience, engineering velocity, and OLI's ability to scale its cloud platform.
Key Responsibilities
- Build, configure, maintain, and support cloud infrastructure in Microsoft Azure.
- Implement and maintain infrastructure as code in Terraform, following established OLI patterns.
- Build and maintain internal tooling, reusable infrastructure modules, and Helm charts that help the wider engineering team ship consistently.
- Build, support, and improve CI/CD pipelines in Azure DevOps to enable consistent, secure, and reliable software releases.
- Deploy and support containerized workloads using Docker, Kubernetes (AKS), and related tooling.
- Monitor infrastructure and application health, investigate alerts, and troubleshoot deployment, availability, capacity, and performance issues.
- Help improve observability through logging, monitoring, tracing, dashboards, and alerting using tools such as Azure Application Insights and Grafana.
- Support incident response and contribute to runbooks, post-incident improvements, and automation that reduces repeat issues.
- Apply established security and compliance controls across cloud environments, including access management, secrets handling, and SOC 2 practices.
- Partner with software engineers and process systems engineers to support cloud deployments and resolve infrastructure-related development issues.
- Document infrastructure configurations, deployment procedures, troubleshooting steps, and operational standards.
- Use AI-assisted engineering tools appropriately to accelerate coding, troubleshooting, documentation, and delivery while maintaining security and code quality.
- Participate in appropriate out-of-hours support (on-call) for critical platform issues.
Requirements
- 3+ years of hands-on experience in platform engineering, DevOps, Site Reliability Engineering (SRE), cloud engineering, or a related infrastructure-focused role.
- Hands-on experience building, deploying, maintaining, or supporting production cloud infrastructure.
- Practical experience with Azure compute, networking, identity, and CI/CD (Azure DevOps or GitHub Actions).
- Experience with Infrastructure as Code principles and tooling.
- Working knowledge of Docker and containerized application environments, and hands-on experience deploying, operating, and debugging Kubernetes workloads, not just authoring manifests.
- Experience with monitoring, logging, alerting, troubleshooting, and core cloud security concepts in production environments.
- Ability to write maintainable code beyond one-off scripts, such as infrastructure modules, internal tools, or automation that other engineers rely on, using a language such as C#, Python, or TypeScript.
- Strong communication and collaboration skills with the ability to work effectively with engineers across disciplines.
- BS in Computer Science, Engineering, or a related discipline, or equivalent practical experience.
