About the role
About the role
As Founding Software Engineer, you will sit at the intersection of product, infrastructure, and AI. You will take part in building Arcline's agentic legal platform, which automates 80% of legal work and manages communication between lawyers and clients.
This is a high-impact role for someone energized by building from zero to one, owning hard technical problems end-to-end, and shipping reliable, scalable systems that power complex AI-driven workflows. You will work in a team of highly talented designers, software engineers and AI engineers, reporting directly to the CTO.
What You'll Do
Product Engineering
- Build and ship full-stack features end-to-end, from data model to UI, with a high bar for reliability and code quality
- Work directly with founders and customers to turn ambiguous problems into shipped product
- Own features through the full lifecycle: scoping, implementation, testing, and iteration based on user feedback
Platform and Infrastructure
- Design and maintain the backend systems and APIs powering our agentic workflows
- Build document processing pipelines that ingest, parse, and structure legal documents at scale
- Own search infrastructure that makes an entire case history instantly queryable
- Own infrastructure and observability for the systems you build, on AWS
AI Engineering
- Build the intake agent that gathers and structures client information before a lawyer ever gets involved
- Build document generation pipelines that draft legal documents from firm playbooks
- Build the systems that generate those playbooks — learning from historical documents to codify how elite lawyers approach recurring work
- Integrate LLM capabilities into product surfaces: streaming responses, inline editing, human-in-the-loop review flows
