About apheros:

We are a startup pioneering metal foam‑based cooling solutions for AI‑data centers and more. Our materials are integrated into cooling solutions for both single and two‑phase direct‑to‑chip liquid cooling - enabling better performance, hotspot management, and energy savings.

Our team is built on curiosity, collaboration, and a shared drive to craft a sustainable future - while having fun along the way! Our offices, labs, and pilot line are close to the train station in Baden, Switzerland, and fully stocked with coffee and cake.

Tasks

• Be the primary pre‑sale technical lead for customers adopting our liquid cooling solutions, engaging deeply with the data centre hardware ecosystem to understand detailed thermal and fluidic requirements
• Develop compelling technical use cases for our customers, as well as performance models that clearly highlight the value, efficiency, and Return on Investment (ROI) of our cooling solutions
• Drive proof‑of‑concept demonstrations and performance validations, showcasing how our solutions meet stringent thermal, fluidic, and operational requirements
• Collaborate closely with internal R&D and Engineering teams to ensure critical customer insights — spanning materials, thermal science, and high‑performance computing needs — are accurately translated into product development
• Build and maintain strong customer relationships, acting as a trusted technical advisor who partners with clients to optimise their thermal performance and overall data centre efficiency

Requirements

• 3‑ to 5‑year experience as an application engineer, solutions engineer, or pre‑sales role, specifically within data centre, high‑performance computing (HPC), or thermal management environments
• A strong technical understanding of liquid cooling systems and data centre cooling requirements
• Excellent customer‑facing skills with a proven ability to build rapport and trust with engineers, systems architects, and executive decision‑makers
• The ability to translate customer application needs and requirements into clear, concise inputs for our Product Development and Engineering teams
• A pragmatic, collaborative, and adaptable mindset comfortable thriving in a fast‑paced, startup environment focused on clear, measurable results

What sets you apart:

• You possess an advanced technical understanding (or degree) in thermal management, fluid dynamics, or data centre infrastructure, enabling in‑depth discussions about complex liquid cooling solutions
• You have a proven track record in technical sales - ideally in electronics hardware, HPC, or data centre environments - with experience in driving customer adoption and leading technical sale cycles
• You genuinely care about customers’ pain points and translate them into concrete, fast‑to‑deploy cooling solutions
• You can work fluidly across R&D, Engineering, Product, and Marketing functions to achieve collective goals

Benefits

• High autonomy to drive product strategy and make a direct, meaningful impact on the company's trajectory and bottom line
• Complete technical ownership of cooling solutions, from initial customer concept and design to successful deployment and post‑sales validation
• A commitment to mutual support, continuous learning, and direct, constructive feedback to help you develop and grow with the company
• Flexible work arrangements supporting work‑life balance
