Institutional rental housing is entering a new era. Legacy CRMs, point solutions, spreadsheets and fragmented workflows are no longer fit for purpose. Lette is building an AI-native, agentic back office that automates property operations end to end. Think Rippling plus Anthropic for rental portfolios.

We are shipping daily and already powering live operations. With ambitious goals for 2026 and beyond, this is your chance to shape the product, team and company from the start.

What you will be building

You will work closely with the founders and early customers to design, build, and scale the core platform. This is not a narrow IC role. You will influence architecture, product direction, and how we work as a team.

You will:

Work across the stack using TypeScript, React, Node.js, Prisma and PostgreSQL
Help deliver intelligent, agentic operations across leasing, rent reconciliation, maintenance, compliance, and finance
Integrate with core systems, fintech providers, and industry APIs
Leverage our distilled LLMs and predictive models through tools like SageMaker, Bedrock, Arcade, and other AI-native infrastructure to power smarter workflows
Own features end to end with full autonomy from design to deployment

We do not expect you to be familiar with all the tools we use. What matters is your curiosity and ability to learn fast.

We move fast, cut scope ruthlessly, and ship value daily via feature flags. You will be instrumental in shaping both the product and engineering culture from day one.

What you'll bring

8+ years in fast-paced engineering environments, ideally at a startup or scale-up
Strong experience with TypeScript/JavaScript, React (or similar), and Node.js
Exposure to infrastructure and backend (we use Prisma + PostgreSQL, hosted on AWS Fargate via CDK)
Product-mindedness: you care about what you build and why it matters
AI-native thinking: excited about what AI can do and how to use it practically (e.g. prompt chaining, function calling, semantic search)
High agency: you find problems, fix them, and communicate clearly
Generalist mindset: happy to jump between frontend, backend, infra, and debugging
Strong collaboration: async and remote-first experience via Slack, Notion, Linear, GitHub

Nice to have:

Experience with scheduling systems, workflows, or proptech
Familiarity with Anthropic, Pinecone, or vector databases

Experience building internal tools or agentic flows using LangChain, LlamaIndex, or similar

What you will get

Founding-level equity
Highly competitive salary depending on location and experience
Work from anywhere
35 days paid leave (incl. Bank Holidays)
Quarterly team off-sites to connect, build and reset
