Solutions Engineer

At Gigaton, we’re on a mission to cut gigatonnes of carbon emissions from the world’s biggest emitting industries (like cement, steel and glass), by building autonomous AI control and optimisation systems that learn and leverage the physics of manufacturing. Our products run heavy industrial plants more efficiently, more stably, and with lower emissions in real time - laying the foundation for the next industrial revolution.

We are a team of scientists, engineers, builders, and operators who love hard problems, have high standards, and want to make change happen in the physical world. We care about deep tech, but we care even more about whether it delivers cost and carbon impact in a live plant, with real people, under real constraints.

With Gigaton, you’ll solve really tough problems in places few people ever get close to, and build something that actually helps the planet. Are you up for the challenge?

About the Role

We’re seeking a Solutions Engineer to join our Solutions Engineering team and sit on the frontline of industrial decarbonisation.

This role blends industrial process expertise, control engineering, and deployment leadership. You’ll work directly with plant management, process engineers and operators to understand complex chemical processes, design optimal AI control strategies, and integrate Gigaton’s AI into live production environments. Your mission is to ensure that we delight our customers, by using our AI solutions to solve critical operational problems and deliver real measurable cost and carbon impact.

Your Main Responsibilities

• Build trust and engagement with plant managers, process engineers and operators by clearly explaining technical decisions and demonstrating measurable benefits aligned to operational needs.

• Analyse plant data to assess and identify opportunities, and evaluate the performance of Gigaton’s software.

• Develop and refine control strategies, leveraging APC, MPC, and PID principles.

• Deploy & integrate Gigaton AI into live plants, ensuring stable, safe, and effective operation.

• Collaborate with plant and process teams to identify optimisation opportunities, tune control loops, and validate performance improvements.

• Collaborate with machine learning engineers to refine algorithms and recommendations based on real-world outcomes.

• Create and refine deployment playbooks and templates, ensuring repeatable, scalable, and high-quality rollouts across plants.

• Act as a feedback loop into Gigaton’s product and machine learning teams, providing field insights that shape our product roadmap.

• Travel to sites (~1 week/month) to work hands-on with teams during commissioning, testing, and optimisation phases.

What a Great Fit Looks Like

• Strong process or control engineering background, ideally in cement, chemicals, energy or heavy manufacturing.

• Comfortable collaborating with operators, plant managers, engineers, and data scientists, bridging industrial know-how with data-driven insights.

• Strong analytical skills and outcome oriented mindset, able to dig into industrial data, identify root causes, generate actionable solutions, and deliver them.

• Excellent communication skills, able to build credibility and trust in complex industrial environments.

• Excellent project management, working independently to drive clear actions for yourself, your team and the customer, delivering against the plan and managing risks across the project.

• Practical problem-solver who enjoys working on real-world process challenges.

• Willingness to travel: regularly to deployment sites (~25%).

You’ll Excel If

• You thrive in dynamic, high impact environments, fast-paced, ambiguous settings excite you, and where every deployment directly contributes to decarbonisation.

• You take ownership, you thrive when you’re given full responsibility for projects and see them through end-to-end. You spot problems and act decisively to solve them.

• You have experience with industrial control (APC/MPC/PID), automation (DCS, PLC) or data (OPC, Historian, LIMS) systems.

• You have an understanding of AI/ML applications, such as forecasting, optimisation, anomaly detection.

• You have implemented or tuned control systems and understand how to balance process stability, quality, and energy efficiency.

• You are confident working across technical, operational, and business interfaces, turning complex problems into structured solutions and can communicate complex ideas to multiple audiences.

Success in This Role Means

• Plants achieve measurable performance improvements - lower costs, reduced CO₂, improved stability.

• Customer process engineers trust you as a reliable partner who understands their world.

• Deployments become more repeatable, efficient, and scalable thanks to your control and process insights.

• Gigaton’s solutions evolve from AI algorithms into robust, operator-friendly process control systems.

You are not expected to check every box, and we’d love to hear from you even if your experience isn’t an exact match.

The interview process

• Talent Partner Screen Call: Meet our talent partner and learn more about Gigaton and the role.

• Hiring Manager Screen: Meet one of our Solutions Engineers and discuss if this role is a good fit for you.

• Technical Interviews:

  • Cement Process Optimisation

    • The Task: Work through a kiln optimisation scenario, balancing process stability, clinker quality, fuel use, and emissions to recommend an operating and control strategy.

    • What it’s assessing: Ability to reason about complex plant dynamics, weigh competing trade-offs, and connect process decisions to overall plant performance and cost impact.

  • Delivery Management

    • The Task: Talk through real examples from your career of owning complex industrial software projects end-to-end, plus problem solving examples and experience working with software teams. You'll then apply that experience to a live Gigaton scenario.

    • What it's assessing: End-to-end delivery and accountability, stakeholder management and communication. Ability to problem-solve individually and with a team in real industrial and customer environments; ability to work effectively with software engineering teams, as well as speed of learning in new domains.

• Operating Principles Interview: Understand how we work and whether Gigaton and you are a good fit for each other.

• Meet with the CEO: Every new potential hire meets Josh

We believe hiring is a two-way process. Just as we’ll reference-check candidates before making a final offer, we encourage you to reference-check us by chatting to team members you haven’t yet met. Ask anything. We’ll answer with Concrete Honestly.

Once interviews are done, we’ll move quickly to a decision, and we’re always happy to give feedback at any stage.

In return for your hard work, we’ll give you

Equity in the company: When we win, you win. You’ll get share options, so you’re part of our journey from the inside.
