Perl Developer
Back End Engineer | Cyber & Data Platforms
London / Manchester / Bath (Hybrid)
We’re partnering with a globally recognised technology organisation operating at the forefront of cyber threat intelligence and large-scale data platforms.
This is not a greenfield build role.
If you enjoy owning real, live production systems, solving complex scaling challenges, and improving platforms that genuinely operate at global impact, this will suit you.
💡 The Opportunity
You’ll join a highly capable engineering team responsible for mission-critical backend systems that power large-scale data analysis and internet intelligence services.
A core part of the role will be maintaining, optimising, and evolving existing platforms, with a strong focus on:
- Reliability
- Performance
- Stability
- Security
There’s also opportunity to contribute to incremental modernisation, working with technologies like Go and TypeScript - but the heart of this role is engineering ownership, not constant rebuilds.
🔧 What You’ll Be Doing
- Owning and improving production backend systems
- Enhancing and maintaining legacy platforms (Perl-based)
- Diagnosing and resolving performance and scaling bottlenecks
- Driving system reliability and incident prevention
- Writing clean, well-tested, well-documented code
- Collaborating across engineering teams to ensure seamless integrations
- Identifying long-term improvements rather than quick fixes
🧠 What We’re Looking For
- Strong experience working on production backend systems
- Background in Perl OR similar backend languages
- Solid SQL knowledge (MySQL/MariaDB) — including query optimisation
- Experience working in Linux environments (CLI tools, scripting)
- Familiarity with cloud platforms (AWS or equivalent)
- Understanding of networking fundamentals (DNS, HTTP, TCP/IP, TLS)
- Experience with CI/CD, Git, and system ownership in production
➕ Nice to Have
- Go or TypeScript experience
- Exposure to event-driven or asynchronous systems
- Docker / Kubernetes
- Experience working on long-lived, high-scale systems
- Interest in cybersecurity or internet infrastructure
🌱 Why This Role?
- Work on systems with genuine global impact
- Join a team that values ownership, autonomy, and engineering quality
- Be part of a business investing in long-term platform evolution
- Strong focus on learning, development, and internal progression
- Competitive benefits package including healthcare, enhanced leave, and equity-style incentives
