Senior Platform Engineer

Senior Platform Engineer

Salary: £80,000 - £90,000

Location: London/Hybrid

At Healthera, we're transforming how people access medicines and healthcare making it simpler, faster and more connected. As one of the UK's fastest growing health tech companies, we partner with over 1,700 pharmacies and support more than a million patients through our market leading digital pharmacy platform, enabling seamless prescriptions, medicine delivery and access to clinical services all powered by innovative, patient centred technology.

Role Overview

We're hiring a Senior Platform Engineer to own and evolve our cloud platform, setting standards and best practices across backend services, frontend static and dynamic deployments, and the GCP infrastructure that underpins them. This role is primarily focused on platform engineering, while remaining deeply hands-on with backend engineering, with responsibilities evenly split between the two.

You'll act as a force multiplier for engineering teams enabling fast, self-service access to infrastructure, CI/CD pipelines and developer tooling, while embedding security-by-default, reliability and scalability into the platform. You'll modernise legacy systems, build new backend capabilities, and make pragmatic engineering decisions that balance delivery speed, quality and long-term maintainability.

Core Responsibilities

Platform Engineering

• Act as a platform enabler, reducing friction and accelerating delivery for product teams
• Provide secure, self-service infrastructure on GCP, managed exclusively via Terraform
• Design and maintain CI/CD pipelines that enable fast, safe, and repeatable deployments
• Embed security and compliance by default through DevSecOps practices and platform guardrails
• Implement observability as a standard: metrics, logs, traces, alerts, SLIs/SLOs
• Define and own cost and observability standards, including budgets, spend alerts, unit economics, SLIs/SLOs, and operational dashboards
• Improve reliability, scalability, and cost efficiency through automation and platform standards

Backend Engineering

• Own, maintain, and evolve backend services across legacy and greenfield systems
• Design and implement scalable backend architectures using Node.js, TypeScript, and NestJS
• Build and operate RESTful APIs and event-driven systems (queues/topics)
• Improve performance, resilience, and data models across MongoDB, ElasticSearch, and relational databases
• Implement backend security best practices: authentication, authorization, data protection, and GDPR compliance
• Contribute to architectural decisions and long-term backend strategy

Why Join Healthera

You'll be a key technical enabler, helping teams move faster by giving them safe, reliable ways to build and ship. You'll focus on creating solid foundations, so engineers don't have to think about infrastructure, security, or costs every time they deliver. Your work will directly support a healthcare platform used by thousands of patients every day.
