Job Specifications
We live in a world that runs on physical industries like energy, logistics, manufacturing. These sectors are essential to our economy and daily lives, yet they are held back by inefficiencies, fragile legacy systems, and decades-old ways of working. This is not just a business problem; it is a societal one. When grids fail, supply chains stall, or factories falter, entire economies are disrupted.
These companies face unique, complex challenges that typical software was never designed to solve. Cogna was founded to change this. Our mission is to give critical industries their own AI-powered Software Factory: a way to build and deploy bespoke digital tools that solve pressing operational challenges.
Since our launch in May 2023, we've seen incredible customer traction and revenue growth. We're backed by leading VCs, including Notion Capital and Hoxton Ventures, and we're building a world-class team to take on one of the most important challenges of our time.
Tackling challenges at this scale takes people who are curious, adaptable, and motivated by impact. If our mission resonates with you, we encourage you to apply, even if your experience doesn't match every requirement. We are committed to building a diverse team that reflects the industries and societies we serve.
Overview
Join a team that is redefining how software is built for critical industries. You will help build and maintain the backend services and integrations that power our SaaS applications, working with modern tech stacks and cutting-edge AI tools. This role is an opportunity to accelerate your growth: you will learn to build robust production systems and master AI-assisted development workflows, focusing on validating logic and delivering high-quality features that solve real-world problems.
What You'll Do
Build and maintain backend features and API integrations (Python, FastAPI, SQL)
Adapt and extend pipelines and front-end outputs, validating automated components
Build connectors for APIs, files, and external systems
Support the integration of LLM-based capabilities with robust evaluation and monitoring
Use AI-assisted development tools to scaffold, refactor, and test code
Collaborate with Solution Strategists, Data Platform, Platform and Support teams
What We're Looking For
We don't expect you to have deep expertise in all these areas. We look for a solid foundation in backend engineering and a strong curiosity to learn the rest.
Python/TypeScript experience (1+ years or strong personal projects); understanding of SQL and data modelling
Familiarity with (or keen interest in) agentic AI coding tools (e.g., Cursor/Codex/Claude Code) to plan, scaffold, refactor, and test
Experience with APIs (REST) required. Exposure to other systems like SFTP, SharePoint, or webhooks is a plus
Interest in or exposure to workflow orchestration (Temporal, Dagster)
Basic familiarity with git, CI/CD concepts, Docker, or cloud platforms (Azure/AWS/GCP)
Interest in AI and raising team AI skills
What We Offer
Competitive salary and share option plan
25 days annual leave, plus public holidays
Excellent pension scheme, fixed at 7.5%
Private healthcare, including family cover and pre-existing conditions
Flexible hybrid working with 2 days per fortnight in our Farringdon office

Access to a gym and fitness classes in our office building
About the Company
Overlooked and unaddressed inefficiencies are slowing down our most vital industries. Whether in utilities, construction, facilities management, logistics, or beyond - complex infrastructure and siloed legacy systems are hampering productivity.
Traditional off-the-shelf software can’t address these unique challenges—and few organisations have the resources for custom-built solutions.
