Improbable
Founding Engineer (Contract)
Remote2h ago
Initial 3-month contract with potential to extend
At Improbable, we build and scale ambitious AI and Web3 ventures shaping the next generation of the internet. For more than a decade, we’ve been developing breakthrough technologies and launching ventures across gaming, defence and virtual worlds.
We work closely with founders, combining capital, technical infrastructure and hands-on operational support to help turn bold ideas into real companies.
You’ll be joining ambitious people who care deeply about building transformative technology and pushing each other to do their best work.
About the role
Most prediction markets are built for outcomes that take days or weeks to resolve. We’re building for markets that resolve in seconds.
You’ll be joining Maybe, an Improbable venture focused on solving that challenge. That means tackling problems most teams have avoided: creating and resolving live markets automatically, working with data fast enough to support real-time decisions, and building pricing models for markets that may exist for only a few moments.
As a Founding Engineer, you’ll play a central role in solving those problems. You’ll define the architecture, build the core systems, and help shape the product from the ground up. Your decisions will influence not just what we build now, but how the product scales over time.
This is a hands-on role with real ownership from day one. You’ll work closely with the GM, moving quickly from prototype to product in a zero-to-one environment.
What you’ll do
Own the technical roadmap from early research and prototyping through to production
Design and build the core systems behind live market creation, pricing and decision-making
Make key architecture decisions, balancing speed, reliability, cost and scale
Build quickly, test ideas early and strengthen what works after validation
Work closely with the GM to shape the product experience, not just the underlying technology
Collaborate with infrastructure partners
Use AI tools and agents as a practical force multiplier to speed up thinking, building and delivery
What we’re looking for
Experience building and shipping production systems, ideally in early-stage or fast-moving environments
Proven ability to design systems where speed and reliability genuinely matter
Familiarity with blockchain products or on-chain systems
Good product judgement and the ability to connect technical decisions to user outcomes
Familiar with Solidity and EVM-based development, including writing, deploying and interacting with smart contracts
Comfortable working in ambiguity and making progress without a fixed playbook
A hands-on, practical mindset with a bias towards shipping
We’re open to speaking with experienced contractors, independent consultants, solo builders and senior technical operators who want to work hands-on on an ambitious early-stage product.
If you want to help shape an ambitious product at an early stage and do meaningful hands-on work from day one, we’d love to hear from you.
