ReOrbit is looking for a Senior EMI/EMC Engineer to take ownership of electromagnetic compatibility across our next generation satellite platforms. You will work at the intersection of hardware, RF, power and avionics, ensuring spacecraft systems operate reliably in demanding electromagnetic environments. This is a hands on role focused on real hardware, real testing and full system responsibility from design to validation.

This is an exciting opportunity to join a fast-growing company and work on next-generation satellite platforms where EMC is mission-critical from day one.

Responsibilities

• Own end to end spacecraft EMC strategy, requirements and verification

• Define EMC requirements across avionics, power, AOCS, RF and payload systems

• Plan and execute full EMC test campaigns at spacecraft level

• Drive grounding, bonding, shielding, and return path design

• Design and review filtering, cable harness, and transient protection approaches

• Perform conducted and radiated emissions and susceptibility analysis

• Define and manage EMC budgets and power quality constraints

• Execute hands on EMC testing (conducted/radiated emissions & susceptibility, ESD, transients)

• Debug issues in lab using oscilloscopes, probes, LISNs, antennas, and spectrum analyzers

• Work cross functionally with avionics, power, RF, AOCS, mechanical, AIT, and software teams

• Identify and mitigate EMC induced failure modes at system level

• Own final EMC readiness and sign off before flight

Skills and Requirements

• 5+ years of EMC engineering experience in spacecraft or aerospace systems

• Strong hands on experience with emissions and susceptibility testing

• Familiarity with ECSS-E-ST-20-07, MIL-STD-461, or DO-160 standards

• Experience working across multiple subsystems (avionics, power, RF, AOCS)

• Proven ability to diagnose and resolve EMC issues on real hardware

• Experience with simulation tools such as ADS, CST, or HFSS

• Proficiency in MATLAB or Python for analysis and modelling

• Hands on experience with EMI/EMC/RF lab equipment

• Comfortable working in integrated hardware/software environments

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
