Middle SRE / DevOps Engineer
Confirmed on the employer's own hiring board on Nov 10, 2026. First seen by Alion on Oct 9, 2026.
About InvestEngine
We're a London-based fintech on a mission to make ETF investing simple and accessible. Over 150,000 clients have trusted us with over £3.5 billion in assets - and we're just getting started.
We've been featured by MoneyWeek, Finder and Forbes, and we're growing fast with big ambitions.
About the role
InvestEngine is growing fast, and so is our engineering team. That means more infrastructure to run, more services to keep healthy and more requests from the people who build on top of it. We're adding a Middle SRE / DevOps Engineer to the DevOps team to keep our cloud platform safe, observable and reliable day to day, and to make it a little better every week.
You'll join a small, senior team, report to the DevOps Team Lead and get hands-on onboarding from experienced engineers. Our platform runs mainly on AWS, with some GCP. This is a hands-on role with no people management. It suits someone who cares what happens to a system after the change is shipped, not just whether the ticket is closed.
What you'll do
Run and maintain our cloud infrastructure, mainly on AWS (EC2, VPC, IAM, S3, Route 53, CloudFront), with some GCP.
Carry out planned maintenance: OS patching, updates and upgrades, backup checks and audit checks.
Verify that MySQL backups actually restore and that failover works - safely, without putting production at risk.
Look after monitoring and logging in Grafana and ELK: tune alerts, cut noise and turn signals into action.
Handle requests from developers, Operations and our managed service partner, including access and permissions.
Automate repetitive work with Python and Bash, and manage configuration with Ansible and Terraform.
Take part in incident response and follow-ups, and help prevent the same issue from happening twice.
Grow into owning a defined part of our infrastructure end to end.
Roughly 60% of your time goes to planned maintenance and improvements, and up to 40% to incoming requests. Coding is limited to infrastructure as code and automation scripts.
Your first 3 months
Weeks 1-2: onboarding, access and security training, runbook review, your first supervised low-risk change and shadowing incident response.
Month 1: handle routine maintenance on your own and fix at least one documented operational gap.
Months 2-3: own an agreed area of the infrastructure and ship at least one meaningful reliability, visibility or automation improvement.
What we're looking for
3+ years of hands-on experience with cloud and Linux infrastructure in production (web products or similar).
Practical AWS experience: you can operate and troubleshoot core services, networking and permissions.
Confident with Docker: runtime, resources, logs and health checks.
Experience with Ansible for repeatable, idempotent configuration.
Monitoring and logging with Grafana and ELK - you know the difference between a signal and noise.
Scripting in Python and/or Bash to automate operational work, with safety checks built in.
MySQL in high-availability setups: backups, restores, replication and failover.
A safety-first approach to production changes: plan, validate, roll back and escalate when needed.
Ownership of what you run after it ships, plus clear written and spoken communication.
English at B2 level or higher and fluent Russian.
Availability during UK working hours, and readiness to help with rare out-of-hours incidents.
You don't need an "SRE" job title. Strong Linux/UNIX administrators who meet these requirements are very welcome to apply.
Nice to have
Terraform (working with existing modules is enough; you won't need to build them from scratch).
Kubernetes.
GCP or other cloud providers.
Understanding of CI/CD pipelines.
Cloud security best practices.
Zabbix.
Experience in fintech or another regulated industry (not required).
Our stack
Cloud: AWS (EC2, VPC, IAM, S3, Route 53, CloudFront), some GCP
Containers: Docker
Config & IaC: Ansible, Terraform
Observability: Grafana, ELK, Zabbix
Data: MySQL (HA setups)
Automation: Python, Bash
What we offer
Real impact early on: you'll own part of the platform that thousands of investors rely on.
Room to grow towards Senior SRE, with support from experienced DevOps engineers.
A say in how we run and improve our infrastructure.
A modern cloud stack and time set aside for improvements, not just firefighting.
Fully remote work with UK-hours overlap.
Unlimited vacation.
A friendly, supportive engineering team.
