Job Title: Lead Engineer
Location: Remote-first (Cardiff office twice a month)
Salary: £85,000 per annum
Overview
Were recruiting for an experienced engineer to take ownership of a cloud architecture that underpins a growing SaaS product used by thousands of customers.
This role combines hands-on engineering with architectural leadership. Youll guide technical direction, redesign core AWS infrastructure, and ensure systems are secure, scalable, and well-governed.
The position is not a management role in the traditional sense. The focus is on technical leadership through design decisions, problem-solving, and hands-on contribution.
Key Responsibilities
* Re-architect and improve an established AWS environment, addressing scalability, security, and governance.
* Design and implement distributed systems, APIs, and data pipelines focused on reliability and maintainability.
* Work hands-on with infrastructure-as-code and application development (~50% hands-on).
* Evaluate technical approaches and run proofs of concept to inform architecture decisions.
* Support and mentor engineers within the team, encouraging sound engineering practices.
* Define and evolve architectural standards and contribute to the roadmap for the wider technology function.
Experience Required
* Proven experience designing and maintaining AWS-based architectures (networking, IAM, security, automation, and monitoring).
* A background in a modern programming language such as Node.js, C#, or Java (the current stack uses Serverless, Node.js, and React).
* Sound knowledge of SQL and experience with NoSQL and data pipelines.
* Understanding of distributed systems, serverless computing, and modern cloud-native patterns.
* Ability to think through complex technical challenges and communicate design choices clearly.
* AWS qualifications are distinctly advantageous.
Preferred Background
This role may suit someone currently working as:
* AWS Solutions Architect
* Senior Software Engineer
* Lead DevOps Engineer
* Senior Data Engineer with strong AWS skills
* Technical Lead in a SaaS or product-focused environment
Why Join
* Opportunity to influence and define how AWS architecture evolves.
* Work across a modern, serverless-first technology stack.
* Exposure to a range of technical challenges at scale.
* Remote-first culture with occasional on-site collaboration in Cardiff.
* Stable environment focused on improvement, not firefighting.
Hours: Monday-Friday, full-time
Environment: Remote-first, collaborative, technically mature
