Senior Backend Engineer

Health Moonshot – Engineering
Alpha is an innovation start-up based in Barcelona, established by Telefonica in early 2016.  Alpha’s mission is to create Moonshots: audacious projects that use radical ideas and breakthrough technology to address some of the biggest challenges in society.  Moonshots are designed to affect 100 Million people or more, be a force for good on the planet, and grow into impactful businesses (see

We are building a team to work on ground-breaking and life-changing projects in the health and learning sector.  More Moonshots are to come in a range of exciting domains.

Alpha Health Moonshot
Worldwide, healthcare costs have been increasing faster than GDP for 50 years, whilst key indicators such as life expectancy have plateaued in many countries.  The root cause is a change in disease burden; across the world, today’s biggest diseases and biggest killers are chronic diseases such as cancer, heart attack, stroke, and mental health disorders.  In fact, for every life saved from infections since 2000, we’ve lost two lives to chronic disease. 

It’s now well-established that the main cause of chronic diseases is everyday behaviours such as poor diet, lack of exercise, using tobacco, excessive alcohol, or lack of sleep.  Yet healthcare systems are not geared-up to manage such behaviours at their source.  To make the challenge even harder, pioneers in neuroscience and behavioural economics have begun to reveal that people are not even really in conscious control of much of their everyday behaviour.

At Alpha, we believe that advances in neuroscience, mobile computing, and machine learning now mean we can help people to take control of their own behaviour, optimise their life, and limit the effects of unhealthy behaviour on their bodies and their minds. 

To support our work, we are partnering with the best academics, developers, companies, and professionals around the world.

We are looking for a Senior Backend Engineer who will be responsible for developing and maintaining service layers in distributed microservice architectures. The Senior Backend Engineer will also act as a liaison with the data engineering and DevOps teams and mentor junior engineers.

Building cutting-edge technology in a Moonshot requires a unique mindset which blends fast-prototyping paradigms with state-of-the-art engineering solutions. One of the main challenges in our environment is the need to move as fast as possible across the innovation funnel, from early-stage proof of concepts to mature products that scale up for population-level impact, while maintaining the right balance between technical debt and speed. For this reason, the Senior Backend Engineer must be extremely comfortable dealing with uncertainty and working according to a non-conventional technical approach and contributing to the creation of processes to increase performance in the engineering team.
·      Develop and maintain Service Layers (APIs, DBs, …) in distributed microservice architectures. Our current backend stack at Alpha Health is 90% NodeJS with typescript, 10% Golang. We use Scala for data engineering services.
·       Implement low-latency and resilient components able to scale up and cope with high traffic volume.
·       Log and monitor all services. Implement processes to react quickly to unexpected issues, with the goal of maintaining record uptime metrics.
Desirable Skills/Attributes:

·      4+ years of experience as Backend Engineer or equivalent role;
·       Academic credentials in computer science, computer engineering or equivalent experience;
·       Experience with cloud-based architecture (we use AWS);
·       Experience building cloud-based data engineering solutions;
·       Experience working in Agile/Scrum methodologies and frameworks;
·       Experience implementing automated testing platforms;
·       Team player with strong motivational skills;
·       Excellent communication skills, fluency in English;
