Eryk Jamroz / Software Engineer | Robotics | Mechanical Design

> Bio

I am an engineer with a mixed software and mechanical background, most comfortable where code meets the physical world. My recent work includes backend development in Java and Go, building RESTful services, maintaining production code, and contributing end-to-end tests in a microservice environment at Visa. Alongside that, I have several years of hands-on engineering experience in mechanical design, mechatronics, manufacturing, prototyping, CNC, and 3D printing. I have worked on satellites, rockets, industrial systems, CAD add-ons, and production tooling. That mix taught me how to move between abstraction and implementation: from APIs and debugging, to structures, tolerances, testing, and real hardware constraints. For roles in robotics and autonomous systems, I bring a practical builder mindset: I like understanding the full system, iterating quickly, and making solutions dependable enough for real operations.

> Mindset & Approach

I bridge software and hardware naturally

I am comfortable moving between backend services, CAD, manufacturing, testing, and debugging, which helps me understand how the whole system fits together.

I focus on practical engineering, not just theory

I enjoy building, validating, and improving things in real conditions, whether that means an API endpoint, a fixture, a rocket subsystem, or a printed part.

I learn fast in unfamiliar domains

My path from mechanical engineering into backend software taught me how to ramp up quickly, ask good questions, and become useful in demanding environments.

I like ownership and iteration

I am motivated by work where I can take responsibility for a problem, prototype solutions, test assumptions, and keep improving until it works reliably.

I value reliability and clarity

Whether in code or hardware, I try to keep systems understandable, testable, and robust enough for everyday use.

Hands-on environments suit me best

I enjoy engineering settings where design decisions meet physical constraints, timelines, and cross-functional collaboration.

Long-term growth matters to me

I am looking for teams where I can deepen both software and robotics skills by contributing consistently to ambitious real-world products.

> Background

Visa (Software Engineering Intern) [01.2025-present]

My current role is focused on backend software engineering in a real production environment. It strengthened my understanding of service-oriented systems, code quality, and delivery in a team setting.

  • Implemented RESTful server logic for a payment validation application.
  • Worked on API microservices in Java and Golang.
  • Contributed end-to-end testing across multiple services.
  • Gained experience maintaining existing code and shipping changes in a professional engineering workflow.

Mechanical, Mechatronics, and Manufacturing Roles [2016-2025]

Across internships and full-time roles, I built a strong base in mechanical engineering, manufacturing, and hands-on prototyping. That experience helps me stay grounded in how real systems are assembled, tested, and improved.

  • At Schem3D, operated and optimized a fleet of 10+ SLA and FDM printers, and prepared CNC programs in Fusion 360 for Haas machines.
  • At Liftero, designed and prototyped structures for a thruster demonstration satellite, using CAD and additive manufacturing for rapid iteration.
  • At the Military Institute of Armament, designed and assembled prototype rocket fin subsystems and supported test activities.
  • At Bosch Digital, maintained SolidWorks add-ons in C# and supported testing and debugging work.
  • Earlier manufacturing roles built practical experience in assembly, maintenance, documentation, troubleshooting, and production support.

Education, Aerospace Projects, and Technical Growth [2018-2025]

My academic background in mechanical engineering, combined with software study and student aerospace projects, shaped the interdisciplinary profile I am building today.

  • BSc in Mechanical Engineering from AGH University of Science and Technology, with multiple scholarships for academic excellence.
  • Additional MSc studies in Computer Science at the Polish-Japanese Academy of Information Technology, focused on software engineering and databases.
  • At AGH Space Systems, led work on liquid rocket feed systems, structures, and propulsion-related development in a student research environment.
  • Worked on sounding rocket projects involving design, fabrication, analysis, and cross-functional teamwork under time and budget constraints.
  • Completed a backend developer course covering Java, Golang, APIs, messaging, tokenization, and application development.
  • Supplemented core studies with courses in aerospace structures, MATLAB data analysis, and advanced SolidWorks modeling.
