Why we read it this way (7)

The title 'Software Engineer' carries no level modifier; advertised seniority is Unspecified. The stated 2–4 years of full-stack experience and scope of work (end-to-end feature delivery on a small team) align with a Mid-level band.

LangGraph and LangChain are listed under 'Bonus' and are therefore preferred. LangGraph is the primary name with LangChain as an alternative since the posting treats them as interchangeable agent frameworks.

LiveKit, Daily.co, and Twilio Voice are listed under 'Bonus' as real-time voice/audio options — marked preferred with the others as alternatives.

Langfuse, LangSmith, and Helicone are listed under 'Bonus' as LLM observability tooling — marked preferred with the others as alternatives.

Salesforce and ServiceTitan appear in the responsibilities narrative as CRM integrations the engineer will work with, not in a requirements section — marked preferred.

Supabase and PostgreSQL are mentioned together in the responsibilities section describing the production environment ('multi-tenant Supabase/Postgres'); they appear as core stack context rather than in a formal requirements block. However, given the role's explicit end-to-end ownership framing and the centrality of this environment to the described work, they are marked as required.

Compensation includes equity on top of the stated base salary range.
