Job description

Working at CreateFuture

CreateFuture is an AI-native consulting partner where people do work that matters and are supported to do it well. We work alongside organisations such as PayPal, adidas, NatWest, FanDuel and Money Saving Expert, building digital products and services that make a difference while always putting people first.

We’re a team of creators. We write code, shape delivery, build go-to-market strategies, develop AI solutions and create the practices that support our people. We work side by side with our clients, challenging what’s not working and helping them to build the future. Our commitment to craft, quality, and culture has helped us scale to over 600 people in just a few years.

CreateFuture is a Great Place to Work-Certified™ company and has won Best Workplaces UK multiple years in a row.

We’re looking for an experienced Senior Fullstack Engineer who is passionate about building scalable, high-quality software and helping teams grow. This is more than a hands‑on engineering role—you'll influence technical direction, mentor other engineers, drive architectural decisions, and help us embed AI and automation into the way we deliver value for our clients.

You’ll thrive here if you enjoy solving complex problems, challenging assumptions, collaborating openly, and taking pride in delivering software that makes a real business impact.

What You’ll Do

• Design, build and maintain scalable, secure and resilient backend systems using Go, alongside rich, responsive frontends built with React.
• Lead technical design and architectural discussions, ensuring solutions are maintainable, performant and aligned with best practices across the stack.
• Develop and evolve RESTful and gRPC APIs with a focus on security, versioning, performance and reliability.
• Build intuitive, high-performance user interfaces in React that integrate seamlessly with backend services.
• Champion engineering excellence through clean code, automated testing, documentation and code reviews.
• Drive delivery across multiple initiatives while balancing speed, quality and commercial value.
• Mentor engineers through coaching, pairing and constructive feedback, helping raise capability across the team.
• Collaborate with cross‑functional teams to solve problems together and deliver outstanding outcomes for clients.
• Research and evaluate emerging technologies, frameworks and AI capabilities that improve how we build software.
• Promote automation wherever possible, removing repetitive work so teams can focus on solving meaningful problems.
• Contribute to a culture of continuous learning, innovation and technical excellence

What You’ll Bring

You’ll have strong commercial experience with:

• Go, including interfaces, error handling, generics and the standard library
• Go concurrency patterns, including goroutines, channels and the context package
• React, including modern hooks‑based development and state management
• TypeScript for building robust, type‑safe frontends
• Go web frameworks and routers such as net/http, Gin, Echo or Chi
• Data access in Go using tools such as database/sql, sqlx, sqlc or GORM
• Authentication and authorisation including OAuth2, OIDC and JWT
• REST API design and implementation, with exposure to gRPC and Protocol Buffers
• Microservices and distributed system design
• SQL databases with strong query optimisation skills
• NoSQL databases
• Messaging technologies such as Kafka or RabbitMQ
• Docker and containerised application development
• Cloud platforms, AWS
• CI/CD pipelines using tools such as Jenkins, GitLab CI or GitHub Actions
• Git and modern software development workflows
• Observability tooling including logging, metrics and distributed tracing (e.g. OpenTelemetry, Prometheus)
• Comprehensive testing across unit, integration and functional layers, including Go's built‑in testing tooling and frontend testing frameworks such as Jest or React Testing Library
• Go modules and dependency management
• Go performance fundamentals, including profiling with pprof, memory management and garbage collection behaviou

Technical Excellence & Craft Mastery

• Write clean, maintainable and highly optimised code across both backend and frontend.
• Set high standards for quality, testing and documentation.
• Coach others in engineering best practices and modern development techniques.

Architectural Leadership
