What the job involves

  • 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
  • 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
