Lead AWS Platform Engineer
Location: London – Hybrid, 2 days per week in the office
Employment: Permanent, Full-Time
Salary Range: £100k - £120k
The Role
We’re looking for an experienced Lead AWS Platform Engineer to take ownership of the design, operation and ongoing evolution of a production AWS environment. This is a senior, highly hands-on individual contributor role for someone who enjoys taking genuine ownership of infrastructure. You’ll be responsible for ensuring the platform remains scalable, resilient, secure and cost-efficient, while acting as the lead technical authority for cloud infrastructure.
You’ll own production data services including Aurora, Redshift and Redis, infrastructure as code, CI/CD pipelines, observability, incident response and disaster recovery. Working closely with Product, Engineering and Data teams, you’ll provide engineering squads with a reliable platform to build on while helping shape infrastructure architecture and DevOps best practice across the organisation.
What You'll Be Doing
- Own and evolve the AWS infrastructure strategy across development, staging and production.
- Design for high availability, scalability, resilience and performance.
- Own production Aurora, Redshift and Redis environments, including availability, failover, backups, upgrades and performance optimisation.
- Build and maintain infrastructure as code using AWS CDK and Terraform.
- Develop and maintain GitHub Actions CI/CD pipelines, including safe deployment and rollback strategies.
- Take ownership of on-call and incident response, leading investigations and producing meaningful postmortems.
- Design, document and regularly test backup and disaster recovery processes.
- Build effective observability across metrics, logging, alerting and dashboards.
- Implement strong cloud security practices including IAM, encryption, patching, vulnerability management and secrets management.
- Optimise AWS expenditure through rightsizing, Reserved Instances, Savings Plans and ongoing cost analysis.
- Lead architecture reviews and promote strong DevOps and platform engineering practices.
- Identify future scale and performance challenges before they become problems.
- Mentor engineers and improve infrastructure knowledge and practices across engineering teams.
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.
What We're Looking For
You’ll have 7+ years' experience across DevOps, SRE, Cloud or Platform Engineering, including significant experience operating production AWS environments.
We're particularly interested in people who have worked within start-up or scale-up environments and have previously acted as the lead or sole owner of cloud infrastructure. You'll ideally bring strong hands-on experience across:
AWS: VPC, networking, IAM, EC2, ECS/Fargate, Lambda, S3, CloudWatch, KMS and Secrets Manager
Infrastructure as Code: Terraform and AWS CDK
Data: Aurora, Redshift and Redis
CI/CD: GitHub Actions
Observability: metrics, logging, monitoring, alerting and dashboards
Security: IAM, encryption, vulnerability management, patching and secrets management
Automation: Python and/or Bash
Reliability: incident management, on-call, postmortems, backups and disaster recovery
You'll have experience making architectural decisions yourself rather than simply implementing designs created by others, and you'll be comfortable balancing reliability, security, scalability, performance and cloud cost.

The Experience That Matters
We'd particularly like to speak with engineers who have:
- 7+ years in DevOps, SRE, Cloud or Platform Engineering.
- At least 3 years' experience running production AWS data services.
- Worked as the lead or sole infrastructure owner within a start-up or scale-up.
- Personally owned production incidents and on-call responsibilities.
- Led investigations and written postmortems following incidents.
- Designed and actually tested disaster recovery and backup restores, rather than simply configuring them.
- A track record of improving AWS cost efficiency and platform performance.
Nice to Have
Experience with Databricks or broader data platforms, working within AdTech or another high-volume data environment, and/or an AWS Professional-level certification would all be advantageous, but aren't essential.
The Person
This role will suit someone who enjoys ownership and autonomy.
You'll be comfortable making decisions around tooling and architecture, taking responsibility for a production platform and explaining technical trade-offs clearly to both engineers and non-technical stakeholders.
We're looking for someone pragmatic rather than dogmatic: someone who prefers simple, reliable solutions, improves existing systems where appropriate and thinks carefully about the trade-offs between resilience, cost, security and scalability.
You'll also care about good documentation, runbooks and sharing knowledge so that critical infrastructure knowledge doesn't live with one person.
Interested?
If you're a senior AWS/Platform/DevOps engineer looking for a genuinely hands-on role with significant ownership of a production cloud environment, we'd love to hear from you.
