Job description

PREP Research Associate

This position is part of the National Institute of Standards (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, thus requires that such institutions must be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration.

Research Title: Robotics Programmer

Robotics Programmer

The work will entail: NIST is focused on the development and integration of robotic software architectures, leveraging ROS2, Java, C#, and C++ to build scalable control frameworks. The work will involve designing robust system interfaces and implementing PLC programming to bridge high-level logic with physical hardware, ensuring seamless interoperability and performance across diverse robotic platforms.

Key responsibilities will include but are not limited to:

• Develop, integrate, and maintain scalable robotic software architectures using ROS 2, C++, Java, and C# in collaboration with NIST researchers.


• Implement Programmable Logic Controller (PLC) programming and design system interfaces to bridge high-level autonomous logic with industrial physical hardware and sensors.


• Build robust device drivers, communication protocols, and APIs to ensure seamless software interoperability and execution across diverse robotic platforms.


• Conduct hands‑on system testing, debugging, and performance optimization on real physical hardware and simulated environments to ensure reliable operation.


• Document codebase architectures, write system user guides, and present regular project progress updates to team members and project leads.

Qualifications

• US Citizens preferred.


• Education: Bachelor's degree or Master's degree in Computer Science, Robotics, Computer Engineering, Electrical Engineering, Software Engineering, or a related field.


• Hands‑on experience developing software applications within the ROS 2 ecosystem.


• Understanding of robotic nodes, topics, services, actions, and custom message types.


• Strong proficiency in C++ and/or Java.


• Proficiency or working experience with C# and Python.


• Experience with PLC programming (e.g., Ladder Logic, Structured Text, or Function Block Diagrams) for industrial automation.


• Experience interfacing high‑level controllers with industrial hardware (e.g., actuators, relays, safety systems, fieldbus protocols).


• Proficient with version control systems and workflows (e.g., Git, GitHub, GitLab, or Bitbucket).


• Experience working in Linux/Unix (Ubuntu) environments as well as Windows.


• Solid grounding in object‑oriented programming (OOP), software testing, and debugging strategies.

Salary Range

The referenced salary range represents the minimum and maximum salaries for this position and is based on Johns Hopkins University's good faith belief at the time of posting. Not all candidates will be eligible for the upper end of the salary range. The actual compensation offered to the selected candidate may vary and will ultimately depend on multiple factors, which may include the successful candidate's geographic location, skills, work experience, internal equity, market conditions, education/training and other factors, as reasonably determined by the University.

Vaccine Requirements

Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID-19 vaccine. This change does not apply to the School of Medicine (SOM). SOM hires must be fully vaccinated with an FDA COVID-19 vaccination and provide proof of vaccination status. We still require all faculty, staff, and students to receive the seasonal flu vaccine.

The following additional vaccine requirements may apply, depending upon your campus. Please contact the hiring department for more information.

Exceptions to the seasonal flu vaccine or COVID-19 vaccine (for SOM) requirement(s) may be provided to individuals with sincerely held religious beliefs or medical conditions that preclude them from receiving the vaccine. Requests for an exception must be submitted to the JHU vaccination registry. For additional information, applicants for SOM positions should visit https://www.hopkinsmedicine.org/coronavirus/covid-19-vaccine/ and all other JHU applicants should visit https://covidinfo.jhu.edu/health-safety/covid-vaccination-information/.

Pre‑employment physical for positions in clinical areas, laboratories, working with research subjects, or involving community contact requires documentation of immune status against Rubella (German measles), Rubeola (Measles), Mumps, Varicella (chickenpox), Hepatitis B and documentation of having received the Tdap (Tetanus, diphtheria, pertussis) vaccination. This may include documentation of having two (2) MMR vaccines; two (2) Varicella vaccines; or antibody status to these diseases from laboratory testing. Blood tests for immunities to these diseases are ordinarily included in the pre‑employment physical exam except for those candidates who provide results of blood tests or immunization documentation from their own health care providers. Any vaccinations required for these diseases will be given at no cost in our Occupational Health office.
