Job description

About Apoha

At Apoha, we are building the Liquid Brain® — a programmable physical sensing platform creating rich, multidimensional fingerprints of materials to unlock faster and smarter material design. Our mission is to redefine how materials are sensed, understood, and designed across industries.

Why Join Us?

We’re Apoha, the team behind the Liquid Brain®.

We're pioneering Sensory Intelligence by decoding molecular behaviour. The first step in our journey to giving machines the senses they never had? Building a Liquid Brain® platform capable of improving life‑saving drugs, by assessing the developability of antibodies earlier (those proteins our immune system makes to fight off bacteria and viruses).

We’re a group of scientists, engineers, and operators who’ve built and launched successful products at Goldman Sachs, Apple, Amazon, and published 50+ high impact research papers across biophysics, materials science, and thermodynamics—and been featured by Scientific American as one of “13 Discoveries That Could Change Everything”.

At Apoha, science isn’t just the foundation of our product—it’s woven into our every day. Whether it’s a journal club over coffee, a spirited scientific discussion unravelling a complex problem, or a full‑company Quarter Demo Day that sparks wild new ideas, we’ve built a place where academic rigor meets startup energy.

Our team is small, flat, and talent‑dense across disciplines. We gravitate towards people who are collaborative, curious, and take pride in owning their work end‑to‑end. We enjoy spirited debate, thinking way beyond the state of the art, and building products that could change how we understand biological materials—forever. We believe in the power of on‑site collaboration, and our UK‑based team works together in our London office to foster creativity, speed, and connection.

Our investors include Redalpine, Acequia Capital, Seedcamp, Nucleus Capital, Plug and Play, Wilbe and others—and we’re just getting started.

What We Offer

• Competitive compensation + stock options
• Private health insurance
• Bi‑weekly team lunches + regular socials
• The rare chance to shape the DNA of a company
• Access to cutting‑edge science, a stellar team, and the chance to change the game

At Apoha, we are committed to fostering a diverse and inclusive workplace. We strongly encourage applications from candidates of all backgrounds, including those from underrepresented groups in tech and science.

The Role

At Apoha, software engineering isn’t just about writing code — it’s about creating the foundation for a breakthrough technology to thrive. As an engineer here, you’ll help shape how the world’s top scientists and researchers interact with the Liquid Brain®.

We’re looking for a Full Stack Engineer who thrives on autonomy, ownership, and creative problem‑solving. This role is ideal for someone who wants to help define the architecture, culture, and best practices of a growing team — someone who’s just as excited by writing clean, scalable code as they are by collaborating with scientists to bring a fundamentally new technology to life.

What you’ll do

• Own and evolve major parts of our software and hardware control stack — from architecture to implementation—ensuring reliability, performance, ease of use, and seamless operation of our Liquid Brain system.
• Design and build user interfaces and backend services (Next.js, Django, Postgres) that make interacting with complex hardware systems and multimodal data analysis tasks simple, intuitive, and robust.
• Work hands‑on with our hardware, using real devices to test, validate, and refine control workflows, automation logic, and system integrations.
• Root‑cause and resolve issues across the entire stack, from hardware drivers to APIs, task management, data analysis pipeline and more.
• Collaborate closely with hardware, scientific, and data teams to translate experimental workflows and engineering constraints into high‑quality product features.
• Help shape the engineering culture by pushing for clarity, simplicity, and technical rigor as we scale the platform.

What We’re Looking For

• Experience building software that interacts with hardware—instrument control, robotics, automation systems, lab devices, edge devices, or similar.
• A strong full‑stack engineering foundation (front‑end + back‑end + APIs + databases), with the ability to ship features end‑to‑end.
• Strong sense of agency, resourcefulness, and ownership is absolutely essential — you care deeply about both the what and the how.
• Proven experience in at least a few of the following areas – designing scalable services, cloud infrastructure, API design and implementation, database design, and front‑end frameworks.
• Curiosity for scientific workflows, new technologies, and solving problems at the intersection of software and physical systems.
• Bonus: exposure to Python, Django, PostgreSQL, AWS, Kubernetes and/or containerized deployments, NextJS, React — but we care more about your mindset than the exact tech stack you have previously worked on.
