Hourly Hmi Developer information

What is an Hourly HMI Developer?

An Hourly HMI (Human-Machine Interface) Developer is a professional who designs, programs, and maintains user interfaces that allow humans to interact with machines or automated systems. They are typically hired on an hourly basis, often for specific projects or ongoing support. Their work involves creating graphical interfaces, configuring control systems, and ensuring that the interface is user-friendly and meets the technical requirements of the application. These developers often work in industries such as manufacturing, automotive, and industrial automation, where effective human-machine communication is critical.

What is the difference between Hourly Hmi Developer vs Hmi Programmer?

AspectHourly Hmi DeveloperHmi Programmer
CredentialsTypically requires a degree in computer science or engineering, with certifications in HMI softwareOften requires similar technical certifications and experience in HMI software
Work EnvironmentContract-based, project-specific work often in manufacturing or automation industriesUsually employed within industrial or automation companies, focusing on software development
Industry UsageCommonly used in industrial automation, manufacturing, and control systemsPrimarily found in automation, process control, and manufacturing sectors

Both roles involve developing and programming HMI systems, but the Hourly Hmi Developer typically works on a contract basis with a focus on project-specific tasks, while the Hmi Programmer may be a full-time employee specializing in HMI software development within industrial environments.

What are the key skills and qualifications needed to thrive as an Hourly HMI Developer, and why are they important?

To thrive as an Hourly HMI Developer, you need expertise in programming languages such as C#, Java, or Python, and a solid understanding of human-machine interface (HMI) design principles, often supported by a relevant degree in computer science or engineering. Familiarity with HMI development platforms like Siemens WinCC, Rockwell FactoryTalk, or Wonderware, as well as experience with PLC systems, is typically required. Strong problem-solving skills, attention to detail, and effective communication set top performers apart when collaborating with multidisciplinary teams. These skills ensure the creation of intuitive, reliable interfaces that optimize user experience and industrial process efficiency.

What are some common challenges faced by Hourly HMI Developers when working on cross-functional teams?

Hourly HMI Developers often collaborate closely with engineers, designers, and project managers to create user-friendly interfaces for industrial or manufacturing systems. A common challenge is ensuring clear communication of technical requirements and design expectations, especially when team members have varying levels of familiarity with HMI tools and protocols. Balancing rapid changes in project scope with the need to maintain interface consistency and usability can also be demanding. Regular meetings and thorough documentation help mitigate misunderstandings and keep projects on track.

Software Engineering Intern (Modeling & Simulation) - Fall 2026

Hermeus

Los Angeles, CA • On-site

$25 - $33/hr

Other

Re-posted 17 days ago

Job description

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

About The Role: 
As a Modeling & Simulation Software Engineering Intern you will work with the software team to develop performant modeling and simulation code for our 6DOF SITL simulation using Julia. You'll Interface with the Flight Software, HMI, and Flight Sciences teams to meet stakeholder needs and ensure accurate results. Your work will involve creating hardware/physics informed software models and validate results with real data. 
 
Fall: Around 16 weeks (August - December)
Responsibilities:
  • Develop performant simulation code for 6 Degrees of Freedom (6DOF) Software-in-the-Loop (SITL) systems using Julia.
  • Develop user driven features and focus on scalability of our Monte Carlo simulation
  • Collaborate with cross-functional teams including Flight Software, Human-Machine Interface (HMI), and Flight Sciences to align simulation outputs with stakeholder requirements.
  • Design and implement physics-informed models that accurately represent hardware behavior and system dynamics.
  • Validate simulation accuracy by comparing model outputs with real-world flight data and refining models accordingly.
  • Optimize simulation performance to ensure real-time execution and scalability across different test environments.
  • Participate in code reviews and testing cycles to maintain high software quality and reliability.
  • Document modeling assumptions, validation results, and integration workflows for internal knowledge sharing and future development.
Requirements:
  • Pursuing a degree in Computer Science, Aerospace Engineering, Electrical Engineering, Applied Mathematics, or a related technical field.
  • Proficiency in Julia or strong experience with scientific computing languages such as Python, MATLAB, or C++.
  • Understanding of 6DOF dynamics and simulation principles, especially in aerospace or robotics contexts.
  • Familiarity with modeling physical systems, including hardware-in-the-loop or physics-informed simulation techniques.
  • Experience with data validation and analysis, including comparing simulation outputs to real-world data.
  • Strong understanding of engineering first principles
  • Demonstrated ability to work within cross-functional teams
  • Enthusiasm for aviation and Hermeus' mission
  • Excellent written and verbal communication skills
  • GPA of 3.0 or above
$25 - $33 an hour
