Full-Stack Elixir Engineer

Location: The Netherlands, Malawi, Tanzania, Rwanda / Remote within Africa or Europe
Impact area: Health tech for hospitals, specifically children, maternal and newborn

About GOAL3

Every year, millions of lives are lost due to a lack of basic health monitoring. At GOAL3, we believe that technology should serve those who need it most. We develop the IMPALA system, a robust, easy-to-use patient monitoring platform designed specifically for environments where resources are limited but the need is great.

We are currently in a scale-up phase whereby we currently operate in about 40 hospitals and expect to reach ~120 before end of year. This growth is also the reason why we want to expand on the capabilities of our platform and want to grow the team.

Why we need you

We are a small, dedicated team. We don't just need a coder; we need a problem-solver who understands that a bug in our code could mean a delay in patient care. We are looking for an engineer who enjoys the 'all-round' nature of the Elixir ecosystem, someone who can jump from debugging a hardware peripheral in Nerves to refining a UI component in Svelte.

Key Responsibilities

• Embedded Systems: Develop and maintain firmware using Nerves to ensure our monitoring devices are resilient and secure in low-connectivity environments.
• Backend Development: Build and scale robust server-side logic with Phoenix and Ecto.
• Frontend Interfaces: Create reactive, intuitive user dashboards using Svelte (integrated with Phoenix via LiveView or as a standalone SPA).
• System Architecture: Design fault‑tolerant systems that can handle real‑time medical data with 24/7 uptime.
• Collaborative Growth: Participate in peer code reviews and contribute to a culture of technical excellence and empathy.

Technical Requirements

• Professional experience with Elixir and the Phoenix framework.
• Proficiency in Svelte or significant experience with modern JavaScript frameworks (React/Vue) and a willingness to transition.
• Familiarity with PostgreSQL and time-series data handling.
• Understanding of IoT protocols and hardware-software interfacing.
• Hands‑on experience with Nervesor a strong background in embedded C/C++ and experience with Buildroot are a plus.
• Experience with data analysis with healthcare data is a plus

What you will bring

• A versatile mindset: You are comfortable working across the full stack and don't mind getting your hands 'dirty' with hardware.
• Technical maturity: You value simplicity, readability, and reliability over 'clever' code.
• Purpose-driven focus: You are motivated by the social impact of your work and want to see your code make a tangible difference in hospitals worldwide.
• Interest in what happens in the field: We are in touch with our users
• Strong communication skills: Can explain complex technical concepts to people who are less technical.

What we offer

• A chance to work on a unique tech stack (Elixir/Nerves/Svelte) in a high-stakes, real-world application.
• A collaborative environment where your voice directly shapes the product.
• The opportunity to contribute to open-source projects within the Elixir community.
• A mission-led culture where we prioritize sustainable growth and human impact over profit margins
• A competitive salary
