Test Engineer

Antare. Product Reliability Engineer (Hardware, Software and Systems). London

About Antare

Do you want to join the (very) early stages of a technology company that's got huge ambition and vision, as well as the backing to make it happen? At Antare, we're utilising our industry knowledge to create innovative products that we believe will disrupt the market. This is a complete greenfield opportunity to be part of a product roadmap from day one, the rest remains in stealth.

The team founded Antare in 2024 comprising product designers and engineers - some of whom have worked together for over 15 years. Together, the companies we have built have been collectively acquired for billions of dollars: we have a genuine level of success under our belts that you could help to contribute to. Today, we're a small, hands-on team spanning product design, finance, hardware, and software engineering.

What we can offer you

This is a rare chance to join a startup at the very beginning - where your curiosity, ideas, and input will directly influence the product roadmap. You'll be working closely with a small, experienced engineering team, building real features in a modern frontend codebase from day one.

We care deeply about helping early-career engineers grow fast and with confidence. You'll benefit from hands-on mentorship, regular feedback, and the chance to pair with engineers who've built products at scale. It's a high-trust, low-ego environment designed to help you accelerate your skills while contributing meaningfully.

We're using modern technology stacks across our infrastructure and frontend, and AI-assisted tooling to move fast and stay focused - and you'll be an integral part of shaping both the user experience and the engineering foundations as we scale.

Role Overview

At Antare, we're building new products that merge advanced hardware, edge AI, and cloud intelligence. As a
Product Reliability Engineer
, you'll sit at the intersection of software, hardware, and field performance - helping ensure that what we ship works flawlessly in the real world, not just in simulation.

You'll design and run hands-on test scenarios, from measuring battery life and thermal performance to validating cellular, Wi-Fi, and GPS behaviour and develop automation that keeps our testing fast, repeatable, and data-driven. This is a role for a curious builder: someone who's as happy wiring up a Raspberry Pi to control a test rig as they are writing Python scripts to process test results.

Responsibilities

• Design and execute system-level tests
  covering power consumption, network connectivity (cellular, Wi-Fi, GPS), audio/video performance, and environmental conditions.
• Meticulously hunt for product bugs and vulnerabilities
  , defects in functional usage, security penetration, making sure the end-to-end solution excels at scale.
• Formulate a test strategy
  and futureproof test coverage across a large and evolving feature set.
• Build and maintain hardware-in-the-loop test rigs
  , using things like Raspberry Pis, microcontrollers, programmable power supplies, and sensors to measure and automate test cycles.
• Develop lightweight automation
  (e.g. in Python, Bash, or Go) to coordinate tests, capture logs, and visualise results - scaling manual insights into repeatable processes.
• Simulate intense, large-scale usage
  to find breaking points and ensure our systems are resilient, reliable, and ready for primetime.
• Work with hardware, firmware and cloud teams
  to validate end-to-end reliability across device, app, and backend systems.
• Simulate real-world operating conditions
  (e.g. variable signal, heat, or motion) to uncover intermittent or long-duration faults.
• Document findings and edge cases clearly
  , collaborating with engineers to fix root causes and improve design robustness.
• Contribute to a reliability mindset
• embedding testability and validation hooks into new designs early in development.

What we're looking for

• A solid foundation in PRE (product reliability engineering), and test, through strong academic study, or hands-on projects.
• Practical experience in
  testing hardware and software systems
  , embedded devices, or IoT products - ideally including power and connectivity testing.
• Comfortable
  building simple test fixtures
  using Raspberry Pi, Arduino, or similar platforms.
• Some
  scripting or automation ability
  (Python preferred), with interest in scaling manual tests.
• Curiosity about how things work (and break), with a structured and methodical approach to experimentation.
• Familiarity with
  video/audio systems
  , sensors, or networking technologies is a plus.
• Enthusiasm to learn - we value resourcefulness and initiative over ticking every box.
• Interest in modern technologies (e.g. Vue, React, TypeScript, Go, Python), and working with video and audio technologies.
• An eagerness to get your hands dirty, test products to their absolute limits, and rapidly accelerate your skills in a fast-paced startup environment.
• Great communication and a collaborative approach to working with others.
• A natural knack for finding edge cases and a genuine passion for understanding how things work (and how they break).

We believe that diverse perspectives make better products, and we strongly encourage people from underrepresented backgrounds in tech to apply. If you're unsure whether you meet every requirement, please still reach out - we'd love to hear from you.

Why Antare

Join Antare in London and contribute to a team that's creating the next generation of innovative products. We offer a competitive salary, equity options, and healthcare, along with the opportunity to build a product that makes a real impact.

While we offer some flexibility, we're primarily an in-person team (3-4 days per week) - at this stage of the company, we've found that collaboration and ideation happen faster and more naturally when we're in the same room.
