ReOrbit is looking for an experienced EGSE and AIT engineer to take ownership of the systems that validate and support spacecraft and payload integration from development through launch readiness. This role is central to ensuring that ground systems accurately reflect real flight hardware behavior, enabling reliable testing, efficient integration, and the discovery of mission-critical issues before they reach orbit. As our Senior EGSE Engineer, you will lead the design, implementation, and evolution of end-to-end EGSE architectures across hardware, software, and operational layers. Working closely with avionics, payload, flight software, and AIT teams, you will drive system-level testing, debugging, and anomaly resolution in a fast-moving environment where hands-on problem solving and engineering ownership are essential. It's an exciting chance to join a dynamic start-up, with the opportunity to make a real impact, to reach our goal of pushing the boundaries of space data transfer. Responsibilities Own the end‑to‑end EGSE system to support spacecraft and payload AIT, ensuring it truthfully represents flight hardware, interfaces, and operational behavior. Translate system‑level and subsystem requirements into executable EGSE architectures, covering electrical, data, timing, software, and operational layers. Design, implement, and maintain robust EGSE hardware and software, including power interfaces, data buses, simulators, emulators, and automated test frameworks. Enable discovery of real flight‑relevant failure modes on the ground, including interface mismatches, timing issues, power sequencing faults, and operational edge cases. Support AIT execution and anomaly resolution, taking direct ownership of debugging, root‑cause analysis, and corrective actions across teams (payload, avionics, FSW, AIT, ground). Skills And Requirements 10+ years of hands‑on experience with spacecraft EGSE, system‑level test, or AIT, with direct responsibility for EGSE design and execution. Direct involvement in at least one spacecraft mission that reached orbit, where the candidate personally owned or built EGSE used for flight hardware validation. Proven experience designing EGSE that interfaces with real flight hardware, not simulations only. Strong practical experience with spacecraft electrical and data interfaces (e.g. power, discretes, SpaceWire, Ethernet, CAN, UART, RS‑422 or equivalent). Software proficiency for test systems (e.g. Python, C/C++, or similar), including test automation, logging, and reproducibility. Experience with payload EGSE, high‑rate data paths, or RF communications subsystem testing. Familiarity with ground segment or mission control interfaces used during EGSE‑based testing. Experience defining or improving AIT processes, regression testing, or test infrastructure scalability. Prior work in small or fast‑moving space organizations, where ambiguity and rapid iteration are normal. Exposure to fault injection, stress testing, and margin testing at system level. What does ReOrbit do? ReOrbit builds the foundation for the next generation of space applications by transforming satellites into truly intelligent, interconnected platforms, defined by software. Our satellite design philosophy revolves around the idea that satellites must network, communicate with each other and thus improve mission efficiency. How can this be achieved? Thanks to a flexible software-first architecture, where all these aspects are dealt with upfront in the mission concept, as integrated functionalities. ReOrbit’s top-notch team of software engineers and system architects develop in-house software, procure hardware from the best-in-class suppliers, and seamlessly integrate the components to create flexible and secure satellites. Today, we are a rapidly growing company building a very strong multidisciplinary team to support our activities. We are headquartered in Helsinki, Finland with a subsidiaries in Bristol, UK and Bariloche, Argentina. Working at ReOrbit At ReOrbit, we are focused on building a strong team as we believe nothing can be accomplished without innovative, humble and curious minds working together on a common goal. We’re all about fostering an inclusive, dynamic environment where equality and diversity are our strength. We offer Challenging but rewarding environment – you will thrive if you are always reflecting on how to make things better. Your ideas will be heard. Ambitious and supportive network of people, who are motivated to change the space industry, bringing expertise from both classic and new space . Benefits such as lunch vouchers, events, parties, occupational health care and additional health insurance - but most importantly a possibility to be a part of a unique and diverse team, connected by similar mindset and sense of humor. We like to spend time together! You can choose activities whichever is to your liking – runOrbit, climbOrbit; become ping pong or board games champion. We support relocation and integration into Finnish society. Join us in our journey of building software enabled satellites for secure communications and, thus, creating the most compelling in space data flow company of the new space era. The Company may require a security clearance for certain positions. Any such security clearance will be conducted in accordance with applicable law and the Company's relevant policies For agencies: We do not accept unsolicited CVs for our open vacancies. Any CV sent to our team unsolicited will reserve us the right to pursue a candidate without obligation to the sender. All candidate submissions must be conducted through our official channels and in accordance with our terms of engagement.
Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
