Job description
As a Senior Backend Developer in our Primary Education team, you'll build Squla, the platform that helps hundreds of thousands of children learn through play every day, and you'll shape both its technical direction and the way our engineering team works. This is a role with real ownership, autonomy, and space for creativity. Your ideas and decisions will directly influence the product and how we build it. AI is changing what senior engineering means, and we're changing with it. As coding agents handle more of the implementation, the leverage shifts to judgment: deciding what to build, designing systems that stay healthy, and shaping ways of working that let a whole team get more from AI without lowering the quality bar. That last part is genuinely yours to define here: how we use agents, what our guardrails look like, what good engineering means in this new mode. You'll combine hands-on development with technical leadership, mentoring, and architectural decision-making. If you've already rebuilt your own workflow around delegating to agents, this is a chance to do the same for a team. Your role and impact o Lead backend planning and technical decision-making together with the PM and your multidisciplinary team o Define how we use AI in engineering: design workflows around agent delegation, parallel execution and review guardrails so the team gains speed without losing quality or accountability o Own significant technical areas and stay accountable for technical quality, system health and maintainability over time o Set up the guardrails, reviews and architecture that allow colleagues from other disciplines to contribute safely, including AI-assisted contributions headed for production o Work broadly across the stack where it keeps momentum high: backend first, frontend, data and infrastructure when useful o Take ownership of team results: you ship, measure whether it moved learning and business outcomes, and act on what you find o Act as a technical mentor and sparring partner for the team o Foster a strong engineering culture through code reviews, knowledge sharing, and collaboration Our stack is: o Python back-end o React front-end o AWS
Requirements
You enjoy taking ownership, making technical decisions, and helping others grow. You thrive in an environment where your ideas matter, your expertise is trusted, and your work has visible impact. You're energized rather than threatened by how fast AI is changing engineering, and you want to help define what good looks like. You bring: o Solid experience as a Senior Backend Developer building production systems o Strong Python experience and confidence owning technical decisions from idea to production and beyond o You've made agent-driven development your daily reality: you delegate complete tasks to coding agents, often several in parallel, you know where they shine and where they quietly fail, and you have ideas about what a team-wide agentic workflow should look like o Experience designing API-driven backend architectures and data modeling at scale, especially with relational databases like MySQL o A deep understanding of software design patterns, automated testing, and clean code practices o The judgment to balance speed against maintainability, security and technical risk o Experience mentoring engineers and reviewing production-bound work from others o Comfort working from goals and ambiguity in a multidisciplinary team o Fluency in English, written and spoken Nice to have: o Hands-on experience with AWS or other cloud platforms
