Own the system design – you decide how data is modeled, where state lives, how components talk to each other, and how the whole system behaves under load
Design and own our data layer from the ground up – tables and relationships, indexing strategy, and query/load optimization that holds up as data and traffic grow
Design queues, background jobs and long-running workflows that stay correct and reliable under heavy load and partial failure
Make the hard, hard-to-reverse design decisions early – and reason explicitly about the trade-offs behind them
Develop and maintain our web application
Contribute to architecture decisions, the direction of our stack, and the overall product vision
Build robust pipelines for document
& email processing and 3rd-party-integrations that handle volume spikes gracefully
Build and optimize agents for our growing template-library
Extend our RAG / knowledge base system (embeddings, semantic search, reranking)
Operate in an AI-first development setup powered by Claude/Cursor
Manage version control and team collaboration via GitHub

A genuine systems-design background – you can design a database from scratch (tables, relationships, indexes) and reason about database load, query performance and data growth, not just write CRUD against an existing schema
The instinct to think in terms of consistency, throughput, failure modes and bottlenecks – you know where the system will hurt before it does
Comfort designing queues, background jobs and long-running workflows, and the judgment to make the hard design trade-offs they involve
You treat reliability, scalability and maintainability as default concerns. If you've read "Designing Data-Intensive Applications" (Kleppmann) – or simply think that way – you'll feel right at home here
