Senior Software Engineer

Senior Software Engineer

London – Hybrid

We're working with a growing, international technology business at a pivotal stage of its scale-up journey. With a high-performing team of around 40 people and ambitious growth plans, the company is now seeking a Software Engineer to help shape the evolution of its systems and support the next phase of scale.

Reporting to the VP of Engineering, this is a senior technical leadership role focused on building reliable, scalable software and improving how systems are designed and delivered. While not a people management position, it carries significant influence across engineering and plays a central role in technical direction, delivery, and engineering standards.

What you'll be doing

Technical leadership & system reliability

  • Owning the design, reliability, and scalability of production systems
  • Leading improvements across application architecture, delivery pipelines, and cloud environments
  • Driving best practices in observability, testing, and operational resilience
  • Ensuring systems and services support continued growth and product development

Technical direction & architecture

  • Partnering with the VP of Engineering on architectural decisions and long-term technical strategy
  • Guiding design patterns and engineering practices across the codebase
  • Helping the team make pragmatic trade-offs between speed, quality, and maintainability
  • Embedding best practice in system design and software engineering

Delivery & engineering excellence

  • Contributing hands-on through coding and end-to-end ownership of features and systems
  • Improving developer workflows, tooling, and engineering efficiency
  • Supporting system scalability, performance, and reliability as usage grows
  • Enabling teams to deliver features quickly, safely, and with confidence

Collaboration & influence

  • Mentoring engineers and raising technical standards across the team
  • Leading through code reviews, technical discussions, and hands-on contribution
  • Collaborating closely with engineers across product and platform areas

What we're looking for

  • 5+ years of software engineering experience
  • Strong experience building and operating systems in cloud environments (e.g. AWS)
  • Solid understanding of software architecture, system design, and scalable services
  • Experience delivering production systems and owning problems end-to-end
  • Broad technical depth across backend systems and modern development practices
  • Influence built on credibility and technical expertise rather than authority
  • Clear communication and pragmatic decision-making
  • Hands-on, delivery-focused, and team-oriented

What you'll get

  • A senior technical leadership role in a business entering its next growth phase
  • High visibility across engineering and executive leadership
  • Real influence over system architecture, engineering practices, and technical direction
