Thermal Engineer
Valve Software
We’re always looking to add talented individuals to our team. For years, Valve has been all about writing software that provides extraordinary gameplay experiences. Lately, we’ve been developing hardware to take those experiences to the next level, and you can be a key part of making that happen! Join our highly motivated team that's doing hardware design, prototyping, testing, and production across a wide range of platforms. Help us invent whole new gaming experiences built around novel hardware for the living room and beyond. At Valve, our Hardware team is highly collaborative; we benefit from individuals with broad skill bases and backgrounds, as well as deep technical experience. We design, test, manufacture, and validate the hardware that brings new experiences to life. Like other teams at Valve, we operate without a traditional management structure. We collaborate with peers to define our priorities and contributions during the development of our products. As part of that collaboration, we are able to self-select how best to add value to the projects we work on. Thermal engineers typically work with ID and ME to design cooling systems that help define the architecture and performance of our hardware products. As a thermal engineer you may find yourself spending time on building thermal models using CFD tools, reviewing or building CAD models, interfacing with suppliers, or running experiments in the lab. You'll likely find yourself involved in multiple hardware projects at one time. There’s a lot to get involved in, and most of the team wears multiple hats. Your hardware colleagues have many years of experience from across the CE industry with multiple products shipped. They can dig into the details while maintaining a product-level perspective, and we believe this focus and awareness results in products that keep our customers engaged and excited. Like most roles at Valve, we don't have headcount targets, we aren’t actively looking to fill an open position, and we don’t generally require specific credentials or qualifications. We’re just always looking for great people to hire. Are you interested in stretching your limits and influencing the future of gaming and entertainment hardware? We look forward to hearing about what you have to bring to the table!Apply now!What We OfferAn organization where 100% of time is dedicated as groups see fitThe opportunity to collaborate with experts across a range of disciplinesA work environment and flexible schedule in support of families and domestic partnershipsA culture eager to become stronger through diversity of all formsExceptional health insurance coverageUnrivaled employer match for our 401(k) retirement planGenerous vacation and family leaveOn-site amenities in support of health and efficiencyFertility and adoption assistanceReimbursement for child care during interviews
