Job description

Location: Remote - Anywhere in Europe - UK Hours must be worked

Contract: Initial 12 Months

This role will suit engineers who enjoy solving difficult technical problems and who are comfortable discussing:

• Data structures
• Algorithms
• Complexity analysis
• Scalability
• Performance optimisation
• Engineering trade-offs

This is not a role focused purely on frameworks or UI development. We're looking for engineers who can reason about systems, design efficient solutions and build scalable software.

What You'll Be Working On

• Designing and building high-performance services using Node.js and TypeScript.
• Creating scalable distributed systems and event-driven architectures.
• Solving performance and optimisation challenges.
• Building reliable APIs and backend platforms.
• Designing solutions for real-world engineering problems with evolving requirements.
• Working closely with senior engineers on architecture and technical strategy.
• Improving observability, reliability and operational performance.

Computer Science & Engineering Fundamentals

You should be comfortable discussing and applying:

• Algorithm design and optimisation
• Time and space complexity
• Performance analysis
• Scalability and reliability principles

Technical Experience

• Experience building production APIs and backend services.
• Experience with distributed systems or event-driven architectures.
• Experience working within cloud environments (AWS, Azure or GCP).
• Strong understanding of software architecture and system design.

Highly Desirable

• Kafka, RabbitMQ, SQS, SNS or similar messaging technologies.
• Microservices and serverless architectures.
• WebSockets and real-time systems.
• React and/or Next.js.
• Docker and Kubernetes.
• Infrastructure as Code.
• Performance engineering experience.

Candidates should be comfortable explaining their thought process, discussing trade-offs and evolving an initial solution as requirements change.

The Kind of Engineer We're Looking For

You're likely to be a strong fit if you enjoy:

• Optimising systems for performance and scale
• Working with algorithms and complex data processing
• Designing robust software architectures
• Understanding how things work beneath the framework layer
