Senior Software Engineer

Node.js - Strong AWS - Docker

£75-85K per annum

Hybrid - Bristol (Max 1 or 2 days per month in Central Bristol office)

We're excited to be the exclusive recruitment partner for a fast-growing SaaS startup that has recently secured Series A funding. With strong, established engineering teams already in place, they're now gearing up for ambitious growth throughout 2025 and beyond.

It’s an incredibly exciting time to join the business - offering the chance to shape the future of their platform while building a standout career for yourself.

The Role:

We’re looking for a Senior Fullstack Engineer who’s excited not only by shipping top-quality platform features but also rolling up their sleeves to improve the infrastructure that powers the magic. This unique role blends application development with infrastructure expertise - ideal for someone who enjoys being the technical bridge between dev and ops.

You’ll be part of the businesses new Platform Team focused on building smarter infrastructure across AWS, improving deployment pipelines, scaling containerised services (ECS), and supporting the engineering team with fast and repeatable environments.

This is not a traditional DevOps role - you’ll ship user-facing features and shape system architecture. You’ll collaborate closely with product-focused teams while being the go-to person for infrastructure questions.

We're looking for a Senior Fullstack Engineer who also has practical infrastructure and devops experience - someone who wears both hats comfortably.

Your Responsibilities:

• Build and maintain fullstack features across Angular/Node.js with MongoDB
  
• Lead the infrastructure evolution - improving AWS architecture (incl. ECS, EC2, S3, Lambda, CloudWatch)
  
• Own and implement Infrastructure as Code (Terraform preferred)
  
• Improve and maintain CI/CD pipelines to optimise deployment workflows
  
• Develop backend services with observability, traceability, and scalability in mind
  
• Design efficient, secure and reliable infrastructure patterns for our cloud-native platform
  
• Help define best practices across DevOps, cloud-native architecture, and developer environments
  
• Contribute to containerisation and compute cost optimisation
  
• Coach and support team members on cloud-native development principles
  
• Take part in shared on-call rotations and incident response improvements
  
  What We’re Looking For:
  
  
• Solid experience across fullstack engineering
  
• Demonstrated AWS infrastructure ownership (especially ECS, EC2, S3, Lambda)
  
• Infrastructure-as-code (Terraform preferred)
  
• Docker
  
• CI/CD configuration management
  
• Ability to build scalable backend services (Node.js)
  
• Understand database and compute scalability within cloud environments, especially with MongoDB
  
• Excellent collaboration and communication skills
  
  Ideal Experience needed:
  
  
• 5+ years in Fullstack Engineering roles, ideally in SaaS or high-growth environment
  
• 2+ years hands-on experience owning and maintaining cloud infrastructure
  
• Led or contributed to infrastructure initiatives as a developer (not just a DevOps specialist)
  
• Experience deploying and managing containerised applications (e.g., ECS, Docker Compose)
  
  Bonus Points:
  
  
• Metrics, tracing and log aggregation experience
  
• Familiarity with cost management or edge-optimised microservices
  
• Experience with TailwindCSS is always a plus!
  
  KEY SUMMARY:
  
  
• This role is great for a Fullstack Engineer who enjoys devops work but does not want to be siloed into ops alone.
  
• We do not want a pure DevOps/Infra person - must be fullstack with an infra affinity.
  
• Strong communication and facilitation skills are a must.
  
  Benefits:
  
  A growing benefits package, including;
  
  
• Flexible working hours - if you need to fit around childcare or need to work around your life, we understand.
  
• Around 32 days of Annual Leave (28 excluding bank holidays and an extended break between Christmas and
  New Year, when we close the office). On-going training where required.
  
• Options scheme for all full-time employees - it’s important to them that everybody owns a part of the company and shares in the benefits of what they build.
  
• Company MacBook to work from
  
• £350 WFH Set-Up
  
• Headspace Contributions
  
• Personal Development budget and support
  
• 2 additional days leave for volunteering
