About the role and team

You’ll join our AI Platform Engineering team, which builds and runs the infrastructure connecting Create Future’s engineers and client workloads to multiple LLM providers — from the inference control plane (the API gateway and routing layer for Anthropic, AWS Bedrock, Open AI, and others) through to the orchestration and lifecycle tooling that turns individual AI integrations into a reusable ‘capability marketplace’, and the trust, safety, and governance controls that keep it all auditable as it scales.

We’re hiring across this team at several levels — Principal, Senior, and

Mid: Principal engineers set technical direction for the platform and act as a trusted extension of the Create Future leadership team day to day; Senior engineers own delivery of key platform components, from the gateway through to orchestration; and Mid-level engineers build hands‑on experience across the gateway, orchestration, and governance layers, with support from senior colleagues.

  • What you’ll be doing
  • Build, run, and evolve the API gateway and routing layer connecting engineers and client workloads to multiple LLM providers (Anthropic, AWS Bedrock, Open AI), including the failover and routing strategies you may need to defend in an incident.
  • Design and build orchestration and lifecycle management for AI capabilities and agents, including the tooling that lets teams register, discover, and reuse capabilities rather than rebuilding them.
  • Implement and maintain RBAC/OIDC access controls and disciplined API key lifecycle management across the platform.
  • Build caching layers and cost/latency optimisation strategies, and the adoption and reuse analytics that show whether the platform is actually being used.
  • Contribute to API design, versioning, and promotion workflows as capabilities move from experimental to production — with more senior engineers setting these standards and more junior engineers learning and applying them.
  • Bring a trust, safety, and governance lens to the platform, helping ensure the agents and capabilities running on it are well‑governed, auditable, and safe to scale.
  • What we’ll offer you
  • We trust people to do their best work. That means flexibility over rigid rules, impact over activity, and real investment in your growth both professionally and personally.
  • You’ll be part of a supportive, and friendly culture, surrounded by smart, curious people who care deeply about what they do.
  • We offer flexible working, including hybrid and remote options.
  • Our office hubs are located in Edinburgh, Leeds, Manchester, London and Bulgaria, with occasional travel to client sites or Create Future offices when needed.
  • We trust you to manage your time balancing collaboration with client time and focused work. What matters is the impact you have, not how busy you look.
  • Hiring process

We try to keep our hiring process clear, fair and respectful of your time.

We aim to get back to everyone who applies and we will be upfront about where you are in the process.

It usually looks like this: Call with our Talent Acquisition Team, Role specific capability interview.

Depending on the role, we might also ask you to do a short presentation, a practical or technical task or have a values focused conversation.

We will explain what is involved before anything happens.

Inclusion at Create Future

We believe diverse teams build better workplaces and better products.

We want Create Future to be a place where people feel able to be themselves and do their best work.

We will do what we can to help.

How to prepare for a job interview at Doist

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Doist uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
