Working hours:

40 hours per week (Monday‑Friday) 08:00 – 17:00

Litta is building operational infrastructure for waste collection at scale.

This role is not a conventional feature‑delivery position. A large portion of the work focuses on improving the systems behind operations, reducing operational overhead, improving reliability, and making the business easier to run as volume grows.

• Ship end‑to‑end features, integrate external systems, and use AI‑assisted tooling to accelerate delivery and reduce manual work.
• Build and maintain frontend applications using Vue, React, and Type Script.
• Develop and deploy backend services using Node.js, Firebase, and Google Cloud.
• Design and evolve APIs, data models, and system boundaries.
• Integrate third‑party systems such as Stripe, Hub Spot, Airtable, and Slack.
• Build and maintain workflow automations using n8n and custom scripts; work with webhooks, queues, and asynchronous workflows as core primitives.
• Replace manual operational processes with reliable, observable systems; own features end‑to‑end, from schema and integrations through to UI and deployment.
• Work in a small, fast‑moving team with lightweight processes; translate rough ideas into working solutions without a dedicated design function.
• Take ownership, get up to speed quickly across multiple codebases, and work across whatever is needed to move things forward.
• Apply AI tools deliberately and appropriately; understand the code you write, apply sound engineering practices, and not rely on AI as a substitute for technical judgement.
• All code, including generated output, is subject to full code review; actively increase automated test coverage across the codebase.
• Importantly, monitor, debug, and improve system performance and reliability.

We use LLMs and modern AI tooling to accelerate development, automate workflows, and enhance product capabilities. You will have access to shared team AI tooling, including a Claude Team subscription, and are expected to incorporate these tools effectively into your workflow.

This is not a ticket‑driven role. You are expected to take ownership of problems end‑to‑end rather than just implementing predefined tasks. Write maintainable, production‑grade Type Script across the stack and ship continuously via CI/CD using tools such as Git Hub Actions.

• Familiar with modern AI tooling in a development workflow.
• Strong Type Script/JavaScript skills across frontend and backend.
• Experience with Vue or similar frameworks, Node.js, and cloud or serverless systems.
• Comfortable owning systems end‑to‑end.
• Experience integrating third‑party APIs and working with webhooks.
• Experience with Firebase or Google Cloud.
• Experience with workflow automation tools such as n8n.
• Background in startups or high‑velocity teams.
• Experience shipping mobile apps using React Native (Expo) or similar.
• Strong product intuition and a bias for simplification.
• 7 or more years building production web applications.
