Home / Compensation / xAI / Software Engineer
Total compensation for a xAI Software Engineer ranges from about $450K at the entry level to $950K+ at the most senior bands, with a typical mid-level package around $620K. Below is the full breakdown by level - base salary, annual equity, and bonus - from public-source data.
Public-source estimates (Beta). Last updated 2026-10. Figures are annualized USD.
| Level | Years | Base (p50) | Equity/yr (p50) | Bonus (p50) | Total (p25-p90) |
|---|---|---|---|---|---|
| MTSMember of Technical Staff / Software Engineer (all levels pooled) | 2-12+ YOE | $220K | $400K | - | $450K - $950K |
Sparse public data - directional. Only the p50 is published (Levels.fyi median $620K; highest report $1.04M); p25/p75/p90 are widened estimates around it. H-1B filings put MTS base at $280K-$400K, above the Levels.fyi median base, so base runs wide. Equity is annualized grant value at the price used when granted.
xAI does not publish a level ladder and Levels.fyi shows no per-level split, so this is one pooled band across all experience levels - not a level. Posted base ranges are very wide ($180K-$440K on most roles), which reflects that one posting covers many seniorities. Equity is the larger half of the reported median.
5 rounds. 5 of them can be practised here - each one below links the rep that trains it.
Application review
Your CV plus a short written statement of exceptional work - the most impressive thing you have built or done. Earlier xAI postings named this statement as the first filter; current postings do not describe the process, so ask the recruiter whether it still applies.
Free rep: What this round looks for →Phone screen
About 15 minutes with a member of the team (an engineer, not only a recruiter), per xAI's published process. Basic technical questions and a walk through your background; candidates report the exceptional-work statement can come up here.
Free rep: Coding challenges with a real sandbox →Technical: Coding
Live coding in your strongest language, or in a language the team names (some infrastructure postings have specified Rust or C++). Candidates report applied problems - implement a cache, iterator, or key-value store - that grow as the interviewer adds requirements, scored on complete, working code more than on the optimal algorithm.
Free rep: Coding challenges with a real sandbox →Technical: Systems design
Distributed systems design, sometimes with implementation in the same session per candidate reports. Reported prompts include rate limiters and batching for model inference. Prompts are open-ended; scope the problem before you design.
Free rep: Design walkthrough: Design an LLM Inference / RAG Platform →Additional coding / team rounds
Candidates describe 2-3 onsite rounds in Palo Alto for some teams - more applied coding, or filling in a partly implemented codebase - followed by a call with the hiring manager or a team member. Round count varies by team.
