Title: Software Engineer

Location: UK Remote

Salary: £65,000 - £85,000 + Bonus

Industry: Web 3 / Blockchain / Cybersecurity

Key words: React / Node / AWS /

Wedo is partnering with a fast-growing cybersecurity company on a mission to protect digital assets across the crypto ecosystem. They’re hiring a Software Engineer to help design and build secure, scalable systems for a new customer. This is a Greenfield project, working part of a small, high performing team and a chance to solve complex challenges working with Web 3 and Blockchain Technology

Expect to work on AWS-heavy infrastructure, high-trust API integrations, and systems that need to perform flawlessly for customers around the globe. This role being “full stack” has a heavy backend bias… likely 80%. So if you’re as more UI based engineer then this role isn’t for you.

What You Should Know Before Applying

• High agency required: You’ll be given problems, not step-by-step instructions. You’ll own them end-to-end.
• Startup-ready: If you’ve thrived in fast-moving, high-ambiguity environments, you’ll feel right at home.
• They can look at a contract to perm or straight perm, ideally if someone available to start immediately.

• Design, build, and maintain secure, high-performance backend services (Greenfield)
• Integrate AWS-based infrastructure with robust API solutions (REST + ideally GraphQL)

• Troubleshoot complex production issues and design long-term fixes

Tech Stack

• Core: React UI, Node Backend with some Python services
• Cloud: AWS (Lambda, API Gateway, S3, KMS, Nitro Enclave)
• APIs: REST (GraphQL a plus)
• DevOps: CI/CD pipelines, automated testing, modern observability tools
• Security-first mindset: Designing for reliability and compliance from day one

Who You Are

• Mid-level Full Stack Software Engineer with a backend bias with Node
• Strong AWS experience and API integration expertise
• Able to work with agency and thrives in a start-up culture
• Comfortable working cross-functionally and communicating clearly in async environments
