Job Description

Full Stack Engineer

London N1 – Full Time – Hybrid – Salary Dependent on Experience

Ready to revolutionize global logistics?

Join Reelables and help us transform how the world tracks packages. We’re pioneering paper-thin smart shipping labels using Bluetooth and 5G to track millions of packages globally — and we’re building the software platform that makes that data usable at scale.

This isn’t a narrow product or UI-only role. You’ll work across the full stack, building customer-facing features end-to-end — from intuitive interfaces through to the APIs, data models, and services that power them. You’ll be hands‑on in the day-to-day, while also helping shape how our platform evolves as we scale.

Who we are:

Reelables is a rapidly scaling tech company based in North London (near Angel), developing the world’s most advanced smart shipping labels. Our technology is already transforming how companies track and manage shipments globally, and we’re still early in that journey.

Product Engineering & Customer Impact

• Own the end-to-end delivery of customer-facing features, from definition through to production
• Work hands-on across the stack to turn complex IoT data into reliable, usable product capabilities
• Build and evolve APIs, services, and data models that support real-time tracking at scale
• Design and implement user interfaces where clarity and usability are critical, without being limited to front-end concerns
• Collaborate directly with customers to understand operational pain points and translate them into practical technical solutions

Technical Ownership & Quality

• Contribute across frontend, backend, and data layers to keep the platform robust, scalable, and maintainable
• Make pragmatic backend changes where needed — improving performance, data access, or service design
• Write production-ready code with strong testing, monitoring, and error handling
• Participate in architectural decisions, balancing speed of delivery with long-term maintainability

Rapid, Hands-On Environment

• Ship code regularly in a lean, fast-moving team where work reaches production quickly
• Take ownership of features beyond initial delivery, iterating based on real usage and feedback
• Help shape development practices as the product and team scale
• Mentor others and contribute to a thoughtful engineering culture

Experience:

Core Technical Skills

• Strong full-stack experience, with confidence working across frontend and backend codebases
• Frontend: Solid experience with TypeScript and modern frameworks (React / Vue)
• Backend: Experience building and modifying APIs and services (Node.js or similar)
• Data & Infrastructure: Comfortable working with databases, data models, and cloud-hosted systems (AWS)
• Engineering Foundations: Familiarity with CI/CD pipelines, testing, and operational best practices

Product-Led Engineering

• Experience building and evolving customer-facing products, not just isolated features
• Comfortable working close to users and understanding how technical decisions affect real operations
• Ability to move between product thinking and hands‑on implementation
• Background in B2B SaaS, logistics, IoT, or data-heavy systems is a bonus

Mindset

• Enjoys working in an environment where engineers have real ownership and autonomy
• Pragmatic problem-solver willing to dive wherever needed across the stack
• Clear communicator who can work effectively with engineers, product, and customers
