THE LAST FRONTIER

Arctic Research and Development (ARD) is building technology to unlock the last great frontier on Earth. An expanse

1.5 times the size of the US, the Arctic is becoming the epicenter of geopolitical tensions, climatic shifts, and economic opportunity. We cut through this complexity — while preserving the integrity of the planet’s most fragile wilderness.

Built by pioneers with 30+ years of polar experience, we know that autonomous systems are the key to operational success. Working at the fringes of technological capabilities, this is a company that takes big bets on hard problems.

If you want to build and deploy ground-up technology with real-world impact - at an inflection point in history that won’t reappear - we want you at ARD.

THE ROLE

We’re hiring an RF Engineer to design and deliver the backbone of our comms and navigation stack — from PCB to polar deployment. In environments where GNSS is degraded or denied, your work will be critical to how our autonomous systems communicate, navigate, and stay mission-focused. You’ll design, build and deploy RF interfaces into field-ready hardware — working closely with systems, software, electronic, and mechanical engineers to ensure a seamless and uninterrupted comms layer in the harshest climate on Earth.

CORE RESPONSIBILITIES

  • Design, simulate, and build RF hardware from first principles — including filters, amplifiers, LNAs, and antennas

  • Conduct evaluation tests (incl. cold-chamber testing) on circuitry to improve reliability and performance

  • Build RF circuits (LNA’s, filters, power amplifiers) as well as support circuitry (power, digital control)

  • Integrate LoRa, INS, and GNSS (incl. RTK & PPK) into full-stack platforms

  • Lead RF integration across our comms and autonomy hardware — optimising for range, reliability, and power

  • Collaborate with in-house engineering teams (Systems, Hardware, Software, GIS)

  • Travel to the Arctic for R&D field testing and meetings with industry representatives

WHAT WE VALUE

  • 5+ years in RF experience across circuits, filters and antennas ideally in GPS denied/degraded environments

  • Degree in Electrical, Systems, or Aerospace Engineering with a demonstrable portfolio of previous work

  • Deep understanding of RF line-up design: input/output power and blocker/jammer tolerance

  • Comfortable working across disciplines —from software devs to field operators

  • The ability to operate with autonomy, take initiative, and consistently deliver high-quality, reliable solutions

  • Readiness to operate in safe but cold environments while conducting R&D prototype field tests

WHAT WE OFFER

  • Stock options and a competitive compensation

  • Mission-driven culture – focus on impact, not hours logged

  • Real field exposure – travel to Arctic sites and Outposts when needed

Skills Required
