The posting

Description

We're looking for a Networking Senior Software Engineer to join our Networking team and build the heart of Halo: Reliable connectivity, multi-link bonding data plane that fuses cellular, satellite, and RF links into one resilient connection.

You'll work across the Halo device and the cloud Halo server, on the same data-plane code that runs on both ends of the tunnel: custom UDP transport, packet sequencing, deduplication and reordering, adaptive per-link scheduling, tunneling, and VPN routing. This is deep, hands-on networking and systems work in Python and C/C++/Cython, on the technology that is quite literally Elsight's product. If you love making unreliable links behave like one solid pipe, you'll have a lot of fun here.

Who are we?

Elsight builds the technology that keeps autonomous systems connected and mission-ready—anywhere, across air, land, and maritime domains. Our Halo platform is already field-proven across more than 500,000 operational hours and trusted by 80+ customers worldwide, from defense forces to commercial operators. We took a bold idea and turned it into a proven public company (ASX: ELS) at the forefront of the autonomy revolution. With 10x year-over-year revenue growth and rapid global expansion, we're scaling fast—and we're just getting started. Join us to work on hard, meaningful problems alongside people who care about getting them right, and to help shape one of the defining technology shifts of the decade.

It’s time to scale up both the product and the team, and we’re looking for people to win with!

You will…

  • Lead network-related initiatives and serve as the primary technical authority in this domain
  • LeadCode review, arechitcure and design activites.
  • Design and build robust, high-performance backend services using Python
  • Develop, and continuously improve back-end systems in cloud environments (AWS)
  • Troubleshoot complex network issues and implement performance improvements
  • Take full ownership of networking features—from planning through architecture, implementation, and deployment

Requirements

Who Are We Looking For

You thrive in a startup environment—balancing quality with timely delivery while working smart, collaboratively, and with purpose. You're independent but team-oriented, a clear communicator who simplifies complexity, driven by curiosity, and passionate about building great things together.

Ideally, you bring:

  • 5+ years of software development experience in network-related products
  • Strong background in developing software for routers, switches, firewalls, or similar network equipment
  • Deep understanding of network protocols (TCP/IP, UDP, HTTP/S, OSPF, PIM, etc.)
  • Strong understanding of Linux networking stack
  • Proficiency in relevant programming languages (Python, C/C++)
  • Linux network development experience and packet processing
  • Background in embedded systems development
  • Bonus: background in IoT connectivity, 4G/5G technologies, or SATCOM
  • Big bonus: you know how to leverage AI tools to expand your capabilities and boost your day-to-day creativity, innovation and productivity

If you’ve made it this far and are excited about the opportunity, don’t let a few unchecked boxes hold you back. If you believe you’re a strong fit for the role, we’d love to hear from you.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
