Job title: Full Stack Product Engineer (Mid-Senior)
Reporting to: Engineering Manager
Working hours: 40 hours per week (Monday- Friday) 08:00 - 17:00
Location: Hybrid (remote-first with a minimum of two days per week at our Canary Wharf co-working space). Candidates must be based within a one-hour commute.
Litta is an innovative and dynamic fast-growing VC-funded Waste-Tech Business that is digitally disrupting the UK's Bulky Waste Collection Sector. Our Mission is to become the UK's leading Bulky Waste Removal Service, using technology to ethically and sustainably collect our customers' waste using approved local waste collection partners.
We are Mac native and use Google Workspace products.
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.
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.
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.
