(Senior) Backend Web Developer Shopify

Sanity

At Sanity.io, we’re building the future of AI-powered Content Operations. Our AI Content Operating System gives teams the freedom to model, create, and automate content the way their business works, accelerating digital development and supercharging content operations efficiency. Companies like SKIMS, Figma, Riot Games, Anthropic, COMPLEX, Nordstrom, and Morningbrew are using Sanity to power and automate their content operations. Sanity Content Agent is where AI meets structured content - an intelligent assistant that deeply understands each customer's content model, follows references like an experienced team member, and combines web research with internal content knowledge in a single conversation. Sanity is uniquely positioned for this moment: we already have a scaled Content Lake holding our customers' structured content, which becomes rich context that generic AI tools simply can't match. Your team will push the boundaries of what's possible when AI truly understands content: auditing thousands of documents in seconds, surfacing inconsistencies before customers do, and generating perfectly structured documents that respect complex validation rules. With a strong and growing team of 4 engineers and room to scale as the product grows, you'll shape the AI capabilities that turn hours of content work into minutes. You'll balance the technical challenges of LLM integration and agentic workflows with the product sensibility to make AI that content teams actually trust.

We also seek someone with strong organizational and planning skills. Leading an engineering team at Sanity is about working with the product manager and designer of the team, to own the strategy, roadmap, and execution. This is achieved by working with great people and creating an environment where your team can shine. As a senior engineering management leader, you’ll be responsible for growing a strong and engaged team to meet these challenges. WHAT YOU WOULD DO: * Helping a team of talented engineers to organize and prioritize their work for the highest impact. * Balance technical excellence with shipping velocity in a fast-moving environment. * Experience working at a product/SaaS company. * Champion developer experience while building for non-technical content creators. * Influencing the direction of both Sanity and of modern web development and content operations. * Work closely with the Head of Engineering, along with leadership in product management and design, to facilitate teamwork and establish processes that can scale as we do. * Supporting the growth and development of your team and team members. ABOUT YOU: * Based in London, UK, or Oslo, Norway, and able to work at least 2-3 days per week in the office. * 1+ years of engineering management experience & 4+ years of engineering experience, ideally in developer tools or content platforms * Strong technical background in TypeScript/JavaScript and modern web technologies * Ability to navigate ambiguity and drive clarity in product direction * Working knowledge of prompt engineering, evaluation frameworks, and techniques for improving model reliability * Understanding of embedding models, vector search, and how to ground AI outputs in structured data * Ability to distinguish AI capabilities that genuinely solve user problems from those that just demo well * Track record of shipping user-facing products at scale * Experience leading teams building complex, extensible applications * An ability to understand software architecture design considerations Not sure you’re exactly what we’re looking for in this role? Apply anyway! WHAT WE CAN OFFER: * A highly-skilled, inspiring, and supportive team * Positive, flexible, and trust-based work environment that encourages long-term professional and personal growth * A global, multi-culturally diverse group of colleagues and customers * Comprehensive health plans and perks * A healthy work-life balance that accommodates individual and family needs * Competitive salary and stock options program WHO WE ARE: Sanity.io is a modern, flexible content operating system that replaces rigid legacy content management systems. One of our big differentiators is treating content as data so that it can be stored in a single source of truth, but seamlessly adapted and personalized for any channel without extra effort.
