What the job involves

• Job title: Full Stack Product Engineer (Mid‑Senior)
• Reporting to: Engineering Manager
• Working hours: 40 hours per week (Monday‑Friday) 08:00 – 17:00
• Litta is building operational infrastructure for waste collection at scale
• This is not a conventional feature‑delivery role
• A large part of the work is improving the systems behind operations
• The focus is on systems that reduce operational overhead, improve reliability, and make the business easier to run as volume grows
• We are hiring a Full Stack Engineer who is comfortable operating across product engineering, internal tooling, and automation
• You will be expected to ship end‑to‑end features, integrate external systems, and use AI‑assisted tooling to accelerate delivery and reduce manual work
• We are a small, fast‑moving team
• Processes are lightweight and not everything will be fully defined or documented
• You need to be comfortable operating in that environment
• You are product‑minded and able to make sensible decisions without heavy oversight
• There is no dedicated design function and few layers of management, so you will be expected to translate rough ideas into working solutions
• You take ownership, get up to speed quickly across multiple codebases, and are willing to work across whatever is needed to move things forward
• Build and maintain frontend applications using Vue, React, and TypeScript. 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, HubSpot, 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
• AI‑Augmented Engineering
• We use LLMs and modern AI tooling to accelerate development, automate workflows, and enhance product capabilities. We identify areas where AI meaningfully reduces cost or improves user experience and implement solutions
• AI is expected to be used deliberately and appropriately. You should 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, and we are actively working towards increasing automated test coverage across the codebase
• 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
• Engineering Quality and Delivery
• 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 TypeScript across the stack. Ship continuously via CI/CD using tools such as GitHub Actions
• Monitor, debug, and improve system performance and reliability
