Senior Software Engineer

Manchester – Hybrid (2x per week)

Highly Competitive Base + Bonus

AWS | .NET | Event-Driven Architecture | Enterprise SaaS

Build the platforms that will define the next decade of a global enterprise SaaS organisation.

We’re partnered with one of the most technologically ambitious enterprise SaaS businesses in Europe as they continue a major modernisation and platform transformation programme across multiple high-scale products.

This is not legacy support work.

This is a genuine opportunity to join a world-class engineering environment building cloud-native platforms, distributed systems, event-driven architecture, and highly scalable backend services used at enormous scale across international markets.

The organisation is investing heavily into modern engineering standards, platform maturity, cloud-native architecture, and long-term product innovation. Engineering is viewed as a strategic function of the business — not a support function.

You’ll join a high-calibre engineering group working alongside strong Product, Platform, Architecture and Engineering leadership teams in an environment that values technical quality, collaboration and continuous improvement.

What you’ll be doing

• Designing and building scalable cloud-native applications using .NET and AWS
• Developing modern distributed systems and event-driven architectures
• Building resilient APIs, backend services and platform capabilities at enterprise scale
• Working closely with Product and Platform Engineering teams on long-term strategic systems
• Contributing to architecture discussions, technical design and engineering best practice
• Improving performance, observability, scalability and reliability across complex platforms
• Mentoring engineers through collaboration, code reviews and technical leadership
• Helping shape the future engineering direction of multiple strategic SaaS products

Tech Environment

• .NET 7 / .NET 8 / C#
• AWS (ECS, EKS, Lambda, EventBridge, SNS/SQS, MSK/Kafka)
• Docker & Kubernetes
• Terraform / Infrastructure as Code
• Event-Driven Microservices
• REST APIs
• SQL & NoSQL technologies
• GitHub Actions / CI/CD
• React & TypeScript exposure across product teams

What they’re looking for

The business is particularly interested in engineers who come from modern enterprise SaaS or product-led environments and have experience building scalable cloud-native systems properly.

Strong preference will be given to engineers with:

• Strong .NET / C# engineering capability
• Commercial AWS experience
• Event-driven architecture experience
• Distributed systems experience
• Infrastructure as Code exposure (Terraform highly desirable)
• Strong backend engineering and systems-thinking capability
• A product mindset and passion for engineering quality

Candidates coming from predominantly Azure-only environments are less likely to progress unless they can clearly demonstrate strong cloud-native engineering principles and transferable distributed systems experience.

Why this role stands out

• Large-scale greenfield and platform modernisation work
• Genuine engineering-first culture
• Modern cloud-native stack
• Enterprise-scale technical challenges
• Long-term strategic programmes with real investment
• High-performing engineering teams with strong technical leadership
• Opportunity to influence technical direction rather than simply deliver tickets

This is the kind of environment where strong engineers can genuinely elevate their careers while working on meaningful, large-scale systems alongside other high-level technologists.
