Job description

Overview

We’re looking for a pragmatic Full Stack Engineer who can lead the evolution of our infrastructure while keeping systems simple, reliable, and maintainable. This is a remote role for someone who enjoys owning infrastructure decisions without stepping away from hands-on product development.

Medify Engineering is a team of ten engineers across two teams, and everyone is hands on, including engineering management and the CTO, which helps us keep our processes practical and engineer-friendly. We work to minimise meetings: engineers typically have a 15-minute daily standup for in-progress updates and quick alignment with Product, plus (per two-week sprint) a one-hour refinement with Product, a one-hour planning session with engineering, and a 30-minute company-wide demo. Operational work like deployments, bug triage, and on-call is handled on a rotation, with each person covering one week roughly every two months.

The Role

In your first few months, you’ll focus on migrating our production environment from Heroku to AWS. Specifically, you’ll take our nascent ECS Fargate and Aurora Serverless v2 setup and turn it into our primary production environment. This is not a greenfield project; the foundations are in place with Terraform, and your role is to take the migration across the finish line.

Once the initial migration phase is complete, you\'ll transition back to feature development, while continuing to own infrastructure decisions and improvements as they come up. This isn\'t a pure infrastructure role - it\'s a full stack position where you happen to be the person who deeply understands how our systems run.

What You’ll Do

• Lead the migration of our production environment from Heroku to AWS
• Mature and own our ECS Fargate and Aurora Serverless v2 infrastructure
• Extend and maintain our infrastructure-as-code setup using Terraform
• Balance infrastructure ownership with ongoing full stack feature development
• Make pragmatic architectural decisions that prioritise reliability and simplicity

What We Value

We\'ve been paged fewer than 10 times this year - mostly for third-party outages or job queues that self-recovered within minutes. We want to keep it that way. We\'re not interested in over-engineered solutions or astronaut architecture. We want infrastructure that works reliably, is easy to understand, and doesn\'t wake anyone up at 3am.

Developer experience matters here. If something makes deploys faster, reduces cognitive load, or eliminates a whole class of problems, we\'re interested. If it\'s clever for clever\'s sake, we\'re not.

What We’re Looking For

• Experience working with AWS and scaling production applications
• Hands-on experience with Terraform, or other infrastructure-as-code tools you can translate from
• Strong full stack fundamentals and a clear understanding of how applications work end-to-end
• A bias toward simple, maintainable, well-understood technologies
• An engineer who designs systems with reliability and on-call sustainability in mind

Why This Role Works

You’ll own a meaningful infrastructure migration, make architectural decisions that impact the whole team, and then return to varied and engaging product work - without being locked into an infrastructure-only silo.

What We Offer

• Competitive salary: £70,000–£85,000, depending on experience
• Fully remote role with flexible working hours
• 25 days’ annual leave, rising to 28 days over three years
• Pension scheme
• Professional development sponsorship (courses, conferences, learning budget)
• Matched charity funding
• Private health and dental care after one year of employment
