At Actinius, we design and build cellular IoT hardware, used by product teams to get connected devices to market faster. Our work spans design to shipped product, and we care about getting the details right.

We’re looking for an Embedded Hardware Engineer who loves designing circuits, working on PCB layouts, and spending real time at the bench. Someone who enjoys the loop of draft -> prototype -> measure -> iterate, and takes pride in hardware that’s reliable, manufacturable, and elegant.

This is a hands-on role. Expect to spend a lot of your time building things in the lab or our production facility. We’re open to candidates from junior through mid-senior level. What matters most is curiosity, fundamentals, and the drive to actually build things.

What you’ll do

• Design schematics and PCB layouts for embedded and IoT devices.
• Build, bring up, and iterate on prototypes.
• Debug at the bench: measure, isolate issues, validate performance against spec.
• Design test fixtures and jigs to support bring-up and production.
• Optimize for low power, manufacturability, and scale.
• Work closely with our firmware engineers on bring-up, and occasionally write low-level drivers or test firmware yourself.
• Support the full product lifecycle: concept, prototyping, production, certification.

What we’re looking for

• Solid grounding in electronics fundamentals. A degree in electrical/electronic engineering is one path here, but we care more about what you can actually do.
• Some hands-on experience designing PCBs, whether through work, university projects, or personal projects you’re proud of.
• Familiarity with a modern PCB CAD tool (Altium, KiCad, or similar).
• Comfortable with lab basics: oscilloscope, logic analyzer, multimeter, SMD soldering.
• Working knowledge of common interfaces: UART, SPI, I²C, USB.
• Comfortable reading datasheets, app notes, and reference designs critically.

Nice to have

• Experience with low-power system design.
• 3D CAD skills (Fusion 360, SolidWorks, FreeCAD, or similar) for enclosures, fixtures, or mechanical integration.
• Familiarity with compliance and certification (CE, FCC).
• Exposure to DFM/DFT.
• Some firmware experience in C, enough to bring up a board on your own.

Why Actinius

• Small team, real ownership: your designs ship.
• Hardware, firmware, production, and connectivity all under one roof, enabling short feedback loops.
• Room to grow: juniors are paired with experienced engineers and get exposure to the full product lifecycle from day one.
• A culture that values craftsmanship, honesty, and curiosity.
• Onsite role in Diemen, Netherlands.

• Track and analyze performance to continuously improve reach and engagement.

What we’re looking for

• A background in marketing, communications, or digital media, with experience in tech or B2B a plus.

• Strong storytelling skills: you know how to make complex things understandable and engaging.

• Hands-on experience with content creation and digital channels (social, web, SEO, newsletters).

• A good eye for design and visuals, even if you’re not a designer yourself.

• Curiosity, initiative, and the ability to work across disciplines.

Nice to have

• Familiarity with technical or B2B marketing.

• Experience with tools like HubSpot, Mailchimp, WordPress, or analytics platforms.

• Interest in hardware/software/IoT and a willingness to dive into new topics.

Why Actinius?

• Work at the intersection of technology, design, and impact.

• Be part of a team that values clarity, honesty, and curiosity.

• Hybrid/onsite role in NL or GR.
