What are some typical challenges faced by a day thermal engineer and how are they addressed within a team setting?

Day Thermal Engineers often encounter challenges related to managing thermal loads and ensuring system components remain within safe operating temperatures, especially in dynamic environments such as manufacturing plants or data centers. To address these issues, engineers collaborate closely with mechanical, electrical, and controls teams to analyze real-time data, troubleshoot anomalies, and implement rapid solutions. Regular team meetings and clear communication channels are essential, as they allow for swift sharing of insights and coordinated responses to any emerging problems, helping maintain optimal system performance and safety.

What are the key skills and qualifications needed to thrive as a day thermal engineer, and why are they important?

To thrive as a Day Thermal Engineer, you need a solid background in mechanical or thermal engineering, heat transfer, and thermodynamics, typically supported by a relevant engineering degree. Familiarity with thermal simulation software (such as ANSYS or COMSOL), CAD tools, and possibly certifications like Professional Engineer (PE) can be highly beneficial. Strong problem-solving skills, attention to detail, and effective communication are important soft skills for collaborating with multidisciplinary teams and presenting technical findings. These skills and qualifications ensure accurate thermal analysis, effective system design, and reliable project outcomes in industries where temperature control and thermal management are critical.

What is the difference between Day Thermal Engineer vs Night Thermal Engineer?

AspectDay Thermal EngineerNight Thermal Engineer
CredentialsBachelor's degree in Mechanical or Thermal Engineering, relevant certificationsSame as Day Thermal Engineer
Work EnvironmentStandard daytime hours, office or lab settingNight shifts, similar environments
Industry UsageCommon in manufacturing, HVAC, automotive industriesLess common, used in 24/7 operations like data centers or manufacturing plants

The main difference between a Day Thermal Engineer and a Night Thermal Engineer lies in their work shifts. Both roles require similar qualifications and work in comparable environments, but they operate during different times of the day to support continuous operations or specific project needs.

What does a day thermal engineer do?

A Day Thermal Engineer is responsible for managing and optimizing thermal systems and processes during daytime operations in various industries, such as manufacturing, energy, or technology. They analyze heat transfer, energy efficiency, and thermal performance to ensure systems run safely and effectively. Their tasks may include designing thermal management solutions, troubleshooting temperature-related issues, and collaborating with other engineers to improve product or process performance. Day Thermal Engineers often focus on maintaining comfortable and efficient working environments or optimizing equipment that operates primarily during the day.

Job description

About magniX: Based in the beautiful Pacific Northwest, magniX builds solutions for the electric age, applying its aerospace-grade batteries, power electronics, power distribution, electric engines, and software to mission-critical applications across data centers, energy storage, defense, mobility, space, and aerospace. Built on an 800-volt architecture, magniX technology delivers industry-leading energy density, cycle life, and safety, and magniX electric engines have powered more than 200 flights across six different airframes, where the company remains the industry leader. As magniX extends its aerospace-grade standards into new markets, we are building a commercial organization to match, and are now ready to take our technology and products to market. Be part of a passionate team that is ushering in the electric age.

About the role: magniX is building a small, cross-functional team to develop a new 800V battery-based power supply and backup system for datacenter compute racks, drawing on the company's deep bench of electric propulsion battery and power electronics expertise. The Mechanical/Thermal Engineer is responsible for the design of a new battery pack and power converter enclosure, built for datacenter rack integration from the ground up. They will own enclosure design, thermal management strategy, and serviceability requirements.

Primary Responsibilities:

  • Design a new enclosure and mechanical packaging for the battery pack and power converter to meet datacenter rack space, weight, and access constraints.
  • Develop thermal management strategy (air- or liquid-cooled) for continuous-duty operation in a datacenter environment.
  • Lead integration planning with rack-level airflow, cooling, and maintenance/service access requirements.
  • Work with the Battery Systems Engineer on thermal interface requirements between cells, modules, and enclosure.
  • Lead mechanical qualification testing (vibration, shock, ingress protection) appropriate to the stationary use case.

Required Qualifications:

  • Bachelors’ in Mechanical Engineering or related field
  • 5+ years in thermal management and mechanical packaging of power electronics or battery systems.
  • Experience with both air- and liquid-cooling system design.
  • Familiarity with high-power-density enclosure design and associated thermal simulation tools.

Preferred Qualifications:

  • Experience packaging automotive or aerospace battery/power systems into stationary or industrial form factors.
  • Familiarity with datacenter rack standards (e.g., EIA-310, OCP) and liquid cooling infrastructure.

Location: Applicants must be willing and able to commute to magniX's location in Everett, Washington.

Compensation & Benefits

  • 100% company-paid premiums for medical, dental, and vision insurance (for employees & dependents).
  • 4 weeks paid vacation + 1-week annual end-of-year shutdown, sick time, and 11 paid holidays.
  • 401K retirement plan with industry leading 9.5% company contribution.
  • Company paid Life insurance, AD&D, Short-Term and Long-Term disability insurance
  • Catered lunches and quarterly company fun-day events!

Salary Range: $120k-$165k
