xAI Forward Deployed Engineer jobs
One req, one wild band: $180k–$440k base to build on the X developer platform.
The Forward Deployed Engineer, X API role
xAI’s sole FDE opening serves enterprise customers of the X API — production integrations and prototypes with agentic Grok use cases, developer tooling (SDKs, MCP servers, CLIs), and ecosystem guides. A developer-platform FDE role, not an enterprise Grok deployment org.
No formal FDE org; xAI merged into SpaceX in February 2026 and rebranded as SpaceXAI in July 2026.
xAI FDE salary
Base: official posting, updated July 2026 — the widest posted FDE band anywhere. Equity on top; no published totals.
