At Sano, our Platform team builds the infrastructure, tools, and systems that power every engineering team. With new product launches, bespoke client needs, and Series B on the horizon, we’re scaling fast - and investing in the foundations that make that possible. 

As a Senior Platform Engineer , this role is a chance to shape how our platform evolves: improving developer experience, scaling infrastructure, and driving reliability across everything we build. You’ll work closely with Engineers, Product Managers, Compliance, and Business Ops to make sure we’re set up for scale - and staying ahead of growing demands.

Headlines:

• Role - Senior Platform Engineer
• Salary - £70,000 - 85,000 pa
• Location - Remote, UK only

What you'll be doing:

• Designing, building and maintaining scalable, secure, and resilient cloud infrastructure
• Defining and adapting processes to support product and engineering teams
• Building and enhancing CI/CD pipelines for faster feedback and safer releases
• Shaping platform solutions that address evolving business needs and technical challenges
• Monitoring system health and performance - proactively tackling issues before they impact users
• Championing best practices in platform engineering across the company
• Contributing to architectural decisions around infrastructure, observability, and cloud-native services
• Mentoring junior engineers and participating in code reviews and design discussions

This job is for you if you have:

• Proven experience in platform, infrastructure, DevOps, or site reliability engineering roles
• Expertise in AWS (IAM, ECS), with strong knowledge of containerisation and orchestration (Docker/ECS)
• Proficiency working with Terraform and automating workflows using tools like CI/CID, GitHub Actions or Python
• Clear communication skills - able to explain complex concepts and tailor to both technical and non-technical stakeholders
• A solid understanding of networking, security, and data handling compliance
• A methodical and detail-oriented approach to problem solving and debugging
• Experience working in fast paced and complex SaaS environments

Even better if you have:

• Experience with monitoring and observability tools (e.g., Honeycomb).
• Background in performance tuning and cost optimisation in cloud environments.
• Experience building and collaborating in a remote-first environment

This role is unlikely to be a great match if:

• You haven’t used Terraform or AWS previously
• You struggle to work autonomously without clear instruction and support.
• You prefer highly defined roles and responsibilities – we need adaptability and autonomy in a fast-growing startup

Research shows that some people are less likely to apply for a role unless they are 100% qualified. Your experience, skills and passion will set you apart so tell us about your achievements, irrespective of whether they are personal or work-related, tell us about your journey, and about what you learnt.

So, if this role excites you, don't let our role description hold you back, get applying!
