Why we read it this way (6)
The role is a genuine hybrid of software/platform engineering (building APIs, SDKs, agentic frameworks, LLM gateway infrastructure) and SaaS platform operations (provisioning, license hygiene, runbooks, access governance for Portkey, Claude, Gemini, Devin, Glean). The primary day-to-day emphasis on building software frameworks and infrastructure code tips it to 15-1252; 15-1244 is the runner-up given the significant operational/administration component.
Location is not explicitly stated in the posting. Realtor.com's primary engineering offices are in Austin, TX and Scottsdale, AZ; Austin is used as the best-guess CBSA. The posting notes a hybrid in-office requirement (3+ days/week), so remote is set to false.
Python, Go, and TypeScript are listed together as interchangeable backend language options under the requirements section ('Proficiency in modern backend languages (Python, Go, TypeScript)'). They are emitted as three separate skills each listing the others as alternatives, since the JD treats them as a set of acceptable options rather than requiring all three.
No compensation figures are provided in the posting.
MCP (Model Context Protocol), A2A (Agent-to-Agent), and ARD (Agentic Resource Definition) are listed as protocols to implement. MCP is the most established; A2A and ARD are emerging/nascent standards with no widely recognized tooling name, so they are captured under MCP rather than emitted as separate skills.
Policy-as-Code is listed as a required practice ('Enforce Platform Governance via Code … directly into the platform fabric as code (Policy-as-Code)') under the responsibilities section, which aligns with the hard-gate requirements block.
