Key roles and responsibilities

Design and deliver a sophisticated EDU rSAM (remaining sales addressable market) model to quantify untapped revenue opportunities across global education markets.Partner cross-functionally with key stakeholders to deeply understand the complexities of the education sector, including diverse subscription models, institutional procurement structures, and consortium-based purchasing dynamics.Collaborate with Data Engineering teams to integrate and operationalise third-party datasets e.g. student population and institutional metrics to create rich, actionable customer intelligence profiles.Work closely with the Product Marketing and Sales Strategy teams to align analytical outputs with go-to-market strategies, pricing frameworks, and commercial objectives at the product-offering level.Design, build, and productionise scalable end-to-end data pipelines incorporating normalised customer attributes, behavioural signals, and finalised rSAM outputs.Combine the EDU rSAM with advanced propensity modelling techniques to optimise education-focused sales motions and accelerate customer growth opportunities.Deliver high-impact strategic insights on market opportunity sizing and customer propensity trends to senior leadership, enabling data-driven decision-making and long-term commercial planning.

Skills Looking for:

5+ years of advanced SQL expertise, with a strong track record in querying, cleansing, integrating, and analysing complex datasets at scale, ideally within Databricks environments.Strong Python capabilities for data manipulation, statistical analysis, and predictive modelling.Demonstrated success in developing, validating, and continuously optimising data science models that directly contribute to revenue growth and commercial performance.Experience with propensity modelling and related predictive analytics techniques is highly advantageous.Exceptional ability to translate complex analytical findings into clear, compelling insights for senior stakeholders and cross-functional audiences.Strong analytical thinking and problem-solving skills, with proven success operating in fast-paced, high-growth environments with evolving business priorities.

Are you a software engineer who likes your code to move real machines? A major name in robotics and automation is building out the team behind one of the largest robotic deployments anywhere - thousands of automated workcells running across high-volume operations - and is looking for a Controls Software Engineer to help keep that fleet fast, stable, and improving.

This isn't a traditional PLC seat. It's a software role that happens to live in a controls world. Most of the team came up through C and C++ and learned the control platform on the job - so what matters here is real software-engineering ability paired with hands-on experience around machines, motion, and hardware.

What you'll work on

Hunting down and fixing bugs and faults in control software running across a large fleet of deployed machinesPushing rate and throughput improvements through the servo, motion, and state-management layersGetting hands-on with hardware in the lab - servos, drives, sensors, vision, and conveyanceTracing problems through telemetry, logs, and alarms, and owning fixes from root cause to rolloutWriting the change documentation and runbooks that keep fleet-wide deployments safe

The live system is written in Structured Text (CODESYS) on Linux-based industrial PCs, with a move to modern C++ already in flight. It's a big, established codebase - strong software instincts matter as much as controls knowledge.

The two things that really matter

Genuine controls experience - you've written software that drives physical hardware: machine control, motion/servo, robotics, or embedded real-time systems.Strong software development in a modern lower-level language - C, C++, Rust, or Structured Text - with the discipline to work cleanly inside a large, mature codebase.

Nice to have

Structured Text on any platform (CODESYS, TwinCAT, Allen-Bradley, Siemens)Embedded, real-time, or industrial software backgroundMotion/servo control, robotics, or pick-and-place / Cartesian workcell experienceSystem-level Linux; EtherCAT or other industrial fieldbusExperience keeping production or large-scale systems running

Level

Open from strong mid-level engineers (3-5 years) who can own their work, through to seasoned engineers ready to plug straight in. The blend of controls exposure and software ability is what counts - not a specific title.
