Lead Backend EngineerCQuel’s mission is to accelerate the decarbonisation of commercial real estate. We do this by providing a SaaS platform to help our consultancies and ESG teams transform themselves into an implementation engine. Our platform gives them the power to write briefs, tender and vet selected suppliers all in one place. This is sustainability but at its core it is engineering; we are focused on getting projects implemented. The world’s first DIY platform for light retrofits!We’re a small but highly skilled team of 9 FTEs working remotely from the UK, Barcelona and Berlin. Our team is multi-disciplinary with significant experience from tech startups, marketplaces and building engineering. All of these different expertises are needed to cope with our rapid traction. After commercial launch in the beginning of this year, we are currently tendering net zero technologies worth more than EUR 20m for 250 assets in the UK and Germany. Our clients are some of Europe’s biggest commercial real estate companies and most prestigious decarbonisation consultancies. To assure that we continuously deliver the best offers, we count on a rapidly growing network of hundreds of vetted suppliers.We’re searching for a Backend Engineer with experience in application development, database design, and a bit of devops to take charge of and own our stack. You’ll be supported by a frontend engineer (if you have some of these skills, great), but you’ll be the main protagonist in our architecture.You’ll be expected to drive decisions around system design, prioritisation, and be a trusted voice in the business for what the “right thing to do” is. This is the right role for someone who wants to feel like they genuinely have a stake in what and why we’re building things, but you must have experience in knowing what to do and with what technology, given limitations.This role is fully remote, although we do have co-working spaces we use in Manchester, UK, and in Barcelona, Spain and a few team members in those areas. We meet at regular intervals throughout the year as a team. We work 9-6 UK time, but have flexibility within that, with team members across Europe. You must be able to work UK/European time.RequirementsExtensive knowledge of Python/Django (our current stack)Deploying, debugging and scaling deployments of full-stack applicationsWorking with Github Actions or similar CI/CD platformsPostgreSQL experience, or similarAt least a good stint working in a B2B product environmentYou want to work here, because our mission matters to youThings we look forCollaborative; you can work with teams within and outside software engineeringSelf-starting: you know how to take an early concept and get an API up quicklyArchitecture savvy: you know how to make pragmatic choicesBroad skills: you’re comfortable with A WS, CI/CD, and integrating with someone’s React app on the same dayCommunication: you raise issues and thoughts earlySelf-aware: you understand your strengths and limitsIdeallyYou’ve worked within a small team and know how to mark your own homework sometimes German speaking (many of our customers are in Germany)Experience working with AI/ML driven productsUnderstanding of decarbonisation and/or the building industryUnderstanding of SAML / SSO authentication workflows
