Job Description
Senior Software Engineer
From internal tools to company-wide workflows, Noloco turns your data into a custom, AI-powered app your team will love to use. We empower teams running complex operations to create custom portals, such as internal tools, client portals, and CRMs. Changing the way small and medium-sized businesses grow and work together.
Backed by Y Combinator, Frontline and other top-class investors, Noloco is a fast-moving, remote-first company with a team spread across Ireland, Spain, and North America.
Our Mission
Our mission is to let businesses of all sizes build truly custom software, without writing code. As a Senior Full Stack Software Engineer, you’ll be a key driver of this mission, working across both the frontend and backend to deliver an exceptional product experience. You’ll shape our AI Co-Builder, APIs, workflow engine, data models, and user interfaces, ensuring performance, reliability, and beautiful UX for customers.
About Us
We pride ourselves on a culture of autonomy, speed, and craft. At Noloco, you’ll join a team that trusts each other to take ownership and execute. You’ll work closely with our founder and product designer and collaborate across product, growth, support, and engineering to ship meaningful improvements end-to-end, from design and implementation to measurement and iteration.
This is a unique opportunity to own entire features in a fast-growing SaaS company and help shape the future of how software is made.
What You’ll Be Doing
- Building end-to-end features across our stack: backend services, GraphQL APIs, and React-based UI
- Advancing the capabilities of Nola, our AI Co-Builder, leveraging the latest improvements from frontier models
- Designing and improving reusable React components and design systems that power Noloco’s app builder experience
- Scaling our backend systems and APIs to handle growing customer demand
- Collaborating with Product and Design to deliver intuitive, polished user experiences
- Improving analytics, observability, monitoring, and alerting across the stack
- Driving technical discussions and mentoring other engineers to raise the bar
What You’ll Actually Be Doing
- Adding new components or improving existing ones to the Noloco App Builder
- Adding more tools/logic to our AI Co-Builder so users can interact with the Noloco platform through chat, or MCP
- Extending our native data tables with new field types, UX improvements, and performance enhancements
- Building integrations with external data sources and APIs to open up new workflows
- Extending Noloco's workflows and automations to let customers connect and automate their tools
- Owning full-stack performance: optimizing queries and frontend rendering
- Monitoring and improving end-user experience from first click to final API call
We'd Love to Hear From You If You Have:
- Significant experience (4+ years) working as a full stack engineer on complex web applications
- Strong JavaScript/TypeScript skills across Node.js and React.js
- Experience designing clean, scalable APIs (GraphQL experience a plus)
- Experience building and improving AI powered agents, workflows and user-experiences
- Solid understanding of frontend performance, state management, and design systems
- A product mindset — you care about the user experience, not just shipping code
- Comfortable working without PM overhead; you want to help to shape the problem, not just implement a spec
- Experience at a startup or a company with a genuinely high engineering bar
