Our Purpose

Improbable builds world-leading simulation technology that helps resolve previously impossible problems. Our technology platforms enable the creation of enormous virtual worlds for training and highly accurate "system of systems” simulations of complex real-world scenarios to facilitate better decision-making.

The Enterprise division of Improbable was formed in 2015. It seeks to create an Optimized World, where simulations of unprecedented scale and complexity provide insights into all of the most important problems faced by businesses and governments. The decisions based on this work will make a safer, more efficient and more prosperous world.

This process is enabled by distributed computation and the abundance of data generated by the digitization of the physical world. We believe that  these huge simulations will be the next fundamental technology of our time. You can read more about our story here.

Our US engineering office is located in Arlington, VA

Your Mission

is to build innovative, product-oriented solutions leveraging and contributing to our R&D effort around probabilistic techniques. We are growing our applied science capability to enable our federal customers to better understand their most challenging problems. Our applied scientists are delivery focused, working in diverse technical teams to design, build, deploy and evaluate models and simulations. You will work with customers to deliver new solutions to some of the most important challenges we face today.

We’ve already built a team of 15 highly experienced engineers, and scientists; now we’re moving onto the next chapter of our growth. We offer competitive salaries, full benefits, training, progression, equity and a chance to be a "founder" of a strategically important new office.

    • Prototype models, iteratively designing robust models that meet the needs of the client’s use case.
    • Critically assess the type and quality of customer data and work with them to appreciate their toughest problems, define modelling assumptions and capture uncertainty.
    • Work closely with our customers to develop a strategy to extract the maximum possible value from the available data
    • Collaborate with engineers to build models in production environments.
    • Be involved throughout customer interaction from project scoping to final delivery
    • Work independently or with our research team to develop a modelling strategy to sit at the core of a data-led simulation-based approach to problem solving
    • Take ownership of ensuring and demonstrating the reliability of the models that we create

    • Additionally you will drive thought leadership within the company and help our clients to understand their data needs and design their data strategies. This involves keeping up-to-date with a diverse body of cutting-edge research, designing and prototyping pioneering new technical approaches and rapidly developing expertise in new subject areas to support new bids and projects.


    • Strong background and experience in delivery of technical, data-rich projects ideally for external clients.
    • Degree in a scientific or mathematical field, ideally with a computational element
    • Pragmatic coding ability - with fluency in at least one relevant programming language and the openness to learn and adapt to a variety of languages. We use Python, Pandas, R and many related tools and libraries.
    • Enthusiastic about continuously improving and rapidly developing new competencies.

The following would be advantageous, but isn't essential

    • Bayesian methods
    • Effectively communicating and visualising analysis of rich data sets
    • Probabilistic programming. You can see our early open-sourced work here.
    • Working with real, complex data
    • Effectively communicating with clients in person, in writing and with visualisation
    • Our office is currently located in Arlington, VA with travel to client sites across N. Virginia
