[Hiring] Senior Backend Engineer @RedTech Recruitment Ltd.

Role Description

A fantastic opportunity for a Senior Backend Engineer to join a growing, integration-focused SaaS company. Working within a small and experienced engineering team, you will build and maintain a wide range of production integrations with external software platforms. This is a highly autonomous role combining hands-on PHP and Symfony development with complex third-party API integration work and increasing ownership of the company’s AWS infrastructure.

Location: Fully remote within the UK. Ideally, you will be based near London, as you must be available to travel to London for occasional team meetings.

Salary: £55,000 - £70,000 per annum depending on experience. Additional paid weekend on-call rota, performance bonus and share options.

Qualifications

• Strong commercial experience developing production software using PHP
• Commercial experience using Symfony
• Proven experience building and maintaining multiple third-party integrations in production
• Experience with REST APIs, webhooks, OAuth, rate limiting, retries, error handling and asynchronous systems
• Strong production experience with AWS, including containers, monitoring and incident response
• Experience with infrastructure as code, ideally Terraform
• Strong understanding of automated testing, code quality and CI/CD practices
• Experience independently troubleshooting integrations involving external systems and incomplete documentation
• A pragmatic approach to engineering, with the ability to balance technical quality against commercial delivery requirements
• Comfortable working autonomously within a small, fully remote engineering team
• Confident proposing solutions and challenging technical decisions constructively
• Willingness to participate in a paid weekend on-call rota - approx. once a month (you will be paid even if no calls are taken)
• Based in the UK, with the right to work
• Experience within payments, travel technology, marketplaces, hospitality or another integration-heavy SaaS environment would be beneficial

Requirements

• Design, build and maintain multiple third-party integrations using PHP and Symfony
• Develop individual microservices connecting the platform with external APIs and webhook-based systems
• Take ownership of a new family of integrations from initial design through to production
• Contribute to platform and API features across the wider software estate
• Investigate production issues and identify whether problems originate from the code, configuration or an external platform
• Learn the existing AWS environment and progress towards significant infrastructure ownership
• Improve observability, automated testing and CI/CD quality gates across the platform
• Support upgrades to current versions of PHP and Symfony
• Contribute informed opinions to architectural decisions as the platform continues to scale
• Participate in a paid weekend on-call rota supporting urgent out-of-hours issues
• Collaborate asynchronously through messaging, pull requests and focused technical discussions

Benefits

• Significant technical ownership within a growing, integration-focused SaaS business
• The opportunity to influence architecture, engineering practices and the future direction of the platform
• Excellent longer-term scope to take on wider technical and management responsibilities as the company grows
