Software Developers, AI Engineer (Applied​/Software)

Job Title: Software Developers – Forecasting Platform

Contract: Permanent

Salary: Competitive, depending on experience.

Location: Remote or Hybrid (Flexible)

Cassi is growing our business around our forecasting and strategy platform, while pursuing our R&D to keep pushing the frontier in AI forward. We are early-stage, currently consistently in the top two globally for LLM forecasting, moving at high tempo, pursuing an ambitious product roadmap while iteratively improving our platform as we go.

We are open to applications from talented individuals and will, where able, tailor roles to your skills and experience.

You will be building an ambitious product that combines AI integration, statistical modelling, and modern UI/UX, delivered as both a SaaS platform and a closed-network deployment.

As a start-up your duties will vary according to customer needs and requirements. We're a start-up, so like everyone else you'll be doing what it takes to enable our shared success from the exciting to the menial.

We are building AI, and increasingly Agent, first. You will be expected to experiment and adapt as we integrate new tools and adjust our workflows to maximise our efficiency and effectiveness. We recognise software development is changing fast, and we want you to help us adapt to thrive in this new era, as we help you do the same (as best we all can – no one – not even those building perhaps the world's leading forecasting platform - really knows how far and fast automation will change all our lives – our promise to you is that once you are on the Cassi team, we will seek to look after you and adapt to the uncertainty together).

You will work between our product designer, lead back-end software developer, lead AI-developer, Cyber Director and Chief Innovation Officer in a close-knit team. We are growing fast, so you are likely helping others settle in as they join too.

• Working AI first
  • Building Cassi's Forecasting & Strategy Workflows. Designing systems that support integrated AI features and advanced statistical analysis
  • Developing UX while Scaling. Contributing to ongoing development with a focus on performance, scalability, and user experience
  • Enabling & Supporting Good Design. Working with our UI/UX lead to build clean, responsive interfaces and interactive dashboards
  • AI-First Development. Tracking, briefing us on, experimenting with and integrating new tools and approaches, AI-first.
  • From Concept to Capability. Collaborating with domain and AI experts on probabilistic models, decision-theoretic outputs, and empowered AI agents
  • Full Stack. Working across the full stack; primary focus for next hires is backend development.

You'll thrive in this role if you are:

• Comfortable in ambiguity, thriving in greenfield environments, and able to create structure through discipline.
• Open to new ideas and keen to experiment with and adopt new tools.
• Low ego, high standards, high discretion.
• Enthusiastic in your work ethic and flexibility.
• Experienced in large distributed complex systems.
• Excited by building and deploying AI platforms.
• Fluent in modern software languages, with strong software engineering principles (1+ year industry experience minimum).
• Passionate about statistics, forecasting, probabilities, or decision theory - you don't need a PhD, but you should get excited about these topics.
• Familiar with secure deployment in both cloud and air-gapped environments.

This is a chance to build something meaningful from what are still our early stages - a platform where every design decision matters, and your technical insight will help shape the future of decision-making, strategy, tactics and more. We're a high-ambition, high-performance team looking to create a team where…
