At hexafarms, we imagine a future where global agriculture produces significantly more food using fewer resources. Growers utilizing hexafarms achieve a 30% increase in yield using the same resources, with reduced complexities. We see this as the dawn of the Fourth Agricultural Revolution, and we want to lead it globally. We’re a rapidly growing startup with an ambition to build the operating system for commercial plant and food production.

As a Fullstack Elixir Developer at hexafarms, you’ll be a key builder of our next growth stage (towards Series A and beyond). Your mission is to:

• Design and implement scalable, reliable server-side applications, APIs, and database integrations with Elixir and Phoenix. 
• Build and maintain intuitive, performant user interfaces that connect seamlessly to backend systems.
• Optimise performance across the stack, ensuring responsiveness, fault tolerance, and long-term maintainability.
• Contribute to architecture decisions that support rapid iteration while keeping technical debt low.

Frontend Development:

• Develop responsive and user-friendly web app(s) using modern frontend technologies (LiveView, Tailwind, some Svelte). Though, we try to stick to Elixir/Phoenix as much as possible.

System Architecture:

• Design and implement system architecture, ensuring scalability, reliability, and maintainability. We try to keep everything as close to the BEAM as possible.
• Stay abreast of industry trends and best practices to continuously enhance the technology stack.

Code Quality and Testing:

• Write clean, maintainable, and well-documented code. Don’t worry, we will help you out to get you to speed if needed.
• Implement and advocate for best practices in testing, including unit testing, integration testing, and end-to-end testing.

• Proven experience in fullstack development, ideally with Elixir or another functional programming language. If Elixir hasn’t been your main language, you should be confident picking up Elixir and the Phoenix framework within a few weeks.

• Some experience with modern frontend frameworks is a plus but not required (e.g., React, Vue, Angular).

• You take pride in writing clean, maintainable, and elegant code.

• Also, we ship new releases every day.

At hexafarms, you’ll experience what it feels like to be a truly productive developer. We are a lean team of 2.5 engineers running an entire infrastructure around a single Elixir binary—powering applications used by growers and agritech teams across 10 countries.

Our platform acts as the backbone for:

• Intensive data and yield forecasting models

• Hundreds of 4K computer vision devices in the field fully managed by our SaaS

• IoT sensor networks and telemetry pipelines

• High-throughput computer vision workflows

You’ll be working alongside colleagues who are top-class in their domains, tackling challenges that cut across distributed systems, computer vision, IoT, and data science. There is never a shortage of new domains to break into– and the scope to shape the future of food production is massive ????
