Sales 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 are looking for a sales engineer to join our sales team and drive the frontline of industrial decarbonisation.

This role bridges the technical and commercial worlds. You'll need interpersonal and technical skills to build relationships with process engineers in cement plants and understand their challenges. Analytical skills will be essential to delve deep into complex plant data and work out how Gigaton's AI products can solve their most critical issues.

Building on that, you'll need strategic thinking and commercial awareness to turn your findings into concise, compelling proposals for decision-makers at our customers, from the C-suite down.

Ultimately, you'll build clarity from uncertainty, making sure we agree a shared roadmap with our customers that puts our solutions on track for significant real-world benefits before a contract is signed.

Over time, you’ll help us evolve our sales approach and shape the product by feeding insights and needs from the plant back to the product team, building the foundation for scaling across industries.

Your main responsibilities

• Be the technical expert on sales calls and visits with cement plants.

• Build trust with process engineers and plant teams by understanding their specific plant issues and linking them to how we can help.

• Analyse plant data to identify and evaluate opportunities, then use this analysis to create compelling sales proposals.

• Lead technical discovery and identify early when a plant does not meet our ICP (ideal customer profile) criteria.

• Make sure relationships and plant understanding are handed over successfully to the deployment team.

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

• Develop and iterate the pre-sales technical process, making it more impactful and more automated each time.

• Travel to plants and conferences, around one week per month, to understand customer environments and explain the product.

What a great fit looks like

• Exposure to physical sciences, controls, or heavy industry, such as cement, steel, energy, manufacturing, or similar.

• Strong analytical skills and an outcome-oriented mindset. You can dig into industrial data, identify root causes, generate potential solutions, and explain their value in dollars and tonnes of CO2.

• Excellent communication skills. You can build credibility and trust in complex industrial environments with both engineers and board-level stakeholders.

• Comfortable being the technical voice in the conversation, presenting to senior plant leaders and operators, handling objections, and being challenged on your findings by people who have run kilns for 30 years.

• Naturally curious and keen to learn about the industry, the technology, and each individual plant. You want to understand the root cause behind every question and objection so you can solve the right problem.

• Confident in ambiguity and able to field very specific technical questions without getting flustered. You know when you can give your understanding, when you need to go and find the answer, and how to maintain customer confidence in both situations.

• Willingness to travel regularly.

You’ll excel if

• You build trust easily. You can connect with plant engineers, listen deeply, and align solutions to their priorities.

• You’d rather diagnose than pitch. Your first instinct in a plant is to ask a better question, not to open the deck.

• You thrive in dynamic environments. Fast-paced, ambiguous settings excite you, and you’re motivated by high-impact, mission-driven work.

• You have experience working in heavy industry, particularly cement, steel, energy, heavy manufacturing, or similar.

Success in This Role Means

• Plants say yes because the technical case is clear. You build customer confidence that Gigaton can deliver high ROI, helping us hit our revenue goals without losing deals because customers don’t understand or believe in our product and capabilities.

• Deployments are set up to succeed. We haven’t overpromised to sign a contract, and our pre-contract analysis holds up once the system is live.

• Process engineers trust and rely on you as a partner in solving problems.

• Deals don’t stall waiting on a technical answer. Objections get handled quickly, and customers get the answers they need in good time.

  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.

  We’re building a team that reflects the world we want to change. Our people come from all walks of life, with different countries, cultures, and experiences, and we think that’s one of our biggest strengths.

  We’re committed to creating a workplace where everyone feels safe, respected, and celebrated. No matter your background, if you’re excited by what we do, we want to hear from you.
