About the Role:

Our client is a UK-based event technology company that designs, develops, and hosts websites for exhibitions, trade shows, conferences, and other events. Their platforms power high-profile events and are built to perform reliably at scale.

We are seeking a skilled and experienced Lead Backend Developer to join our development team. You will design, develop, and maintain scalable backend systems and RESTful APIs, with a strong grasp of server-side logic, database integration, and modern backend frameworks.

As a key member of the backend team, you will work closely with Frontend Developers, DevOps Engineers, and Product Managers to deliver robust, high-performance applications. Strong expertise in Node.js, TypeScript, database integration, and cloud services is essential, along with the ability to mentor developers and contribute to long-term technical strategy.

What You Will Be Doing:

• Partner with our technical lead to analyze and understand the existing backend architecture of the product, taking ownership of its architectural evolution, and helping to drive modernization into a scalable, secure, high-performance microservices-based architecture.
• Own technical implementation, making high-level architectural decisions, and define strategies for long-term system scalability.
• Conduct code reviews, promote clean and maintainable code, and mentor junior and mid-level developers.
• Collaborate with Product Managers, Quality Assurance engineers, Developers, and consultants to translate business requirements into effective technical solutions and implementation plans.
• Deliver assigned tasks on time and to agreed standards, while supporting other team members.
• Troubleshoot and resolve complex technical issues and escalated incidents, identifying root causes and implementing effective fixes.
• Research emerging technologies, evaluate new tools and approaches, and recommend innovations that improve software quality, performance, and scalability.
• Continuously develop your technical knowledge and contribute ideas that support the adoption of suitable technologies across the organization.
• Communicate technical concepts clearly to both technical and non-technical stakeholders.

What We're Looking For:

• B.Sc. degree in Computer Science, IT, Engineering, or a related discipline
• Overall, 10+ years of experience as a Backend Developer, with a minimum of 5 years in the capacity of a Lead Backend Developer.
• Strong proficiency in Node.js, TypeScript, or JavaScript (ES6+)
• Solid understanding of Node.js internals: the event loop, non-blocking I/O, streams, clustering, and worker threads.
• Hands-on experience with Node.js frameworks such as NestJS, Express.js, Fastify, Hono or Koa.js, and package managers such as npm, pnpm and Yarn.
• Strong knowledge of data structures, algorithms, software design principles, and design patterns.
• Experience designing, developing and consuming RESTful APIs, GraphQL services and real-time applications using WebSockets.
• Experience with microservices, distributed systems, event-driven architectures, and messaging platforms such as Kafka and RabbitMQ.
• Experience with relational and NoSQL databases, data modelling, indexing, and query optimization.
• Experience with caching mechanisms such as Redis.
• Familiarity with cloud platforms (AWS, Azure, GCP), Docker, Kubernetes, and CI/CD pipelines.
• Experience with logging frameworks, monitoring, distributed tracing, and observability tools, including Prometheus, Grafana, and Loki.
• Experience writing unit tests with Jest or Mocha and integration and/or contract tests, as well as using code quality tools such as SonarQube or Codescene, and managing code with Git.
• Understanding application security, including OAuth 2.0, JWT, RBAC, data encryption and the OWASP Top 10.
• Proven ability to mentor and influence technical direction within a team.
• Strong problem-solving skills and a proactive approach to staying current with Node.js technologies, frameworks and practices.
• Excellent communication skills across technical and non-technical audiences.
