How to Hire DeepSeek V4 Pro Inference Engineers in Tokyo — the 7-Step Playbook for SusHi Tech 2026 Week

Following DeepSeek V4-Pro release on April 24, 2026 and the start of SusHi Tech Tokyo 2026 on April 27, Tokyo employers are racing to hire senior inference engineers. Here is the 7-step playbook to win that race in 4 to 11 weeks.

Step 1 — Build a V4-Pro-specific scorecard (week 1)

Generic ML engineering JDs lose time. Build a V4-Pro-specific scorecard with these must-haves:

• vLLM or TensorRT-LLM production experience.
• GPU quantization (FP8, INT4) and MoE routing optimization.
• Triton or KServe deployment on Kubernetes.
• Capacity planning on H100/H200 or MI300X.
• Latency budget understanding (P50/P95/P99 under load).
• Hugging Face ecosystem familiarity.
• Japanese LLM evaluation awareness if your product targets domestic users.
• On-call discipline and post-mortem culture.

Step 2 — Source via 4 SusHi Tech-aligned channels (weeks 1-2)

Run 4 sourcing channels in parallel:

1. SusHi Tech booth presence at Tokyo Big Sight April 27-29.
2. LinkedIn Boolean search: "DeepSeek" OR "vLLM" AND "production" AND Tokyo.
3. Hugging Face top contributors to inference endpoints.
4. Tokyo AI meetups: ML Tokyo, Tokyo MLOps, Sakana Open Source.

Average channel mix that wins in Q2 2026: 30 percent SusHi Tech contacts, 35 percent LinkedIn, 20 percent Hugging Face, 15 percent meetups.

Step 3 — Pre-screen with a 60-min H100 live coding (weeks 2-3)

Replace whiteboard with a real H100 live coding session with V4-Pro loaded. Three measurable tasks:

• Reduce model load time from 8 minutes to under 3 minutes.
• Diagnose a P95 latency spike on a real query.
• Argue an FP16 vs FP8 quantization tradeoff cleanly.

Candidates who do not address two of three in 60 minutes do not progress. Saves an average of 12 hours interview time per loop.

Step 4 — On-site architecture interview (weeks 3-4)

The on-site moves beyond coding. Run a 90-min architecture interview with these scenarios:

• Capacity planning for V4-Pro on Sakura Internet at 2,000 RPM peak.
• MoE quantization for multi-tenant deployment.
• Incident: model returns 500 errors on 0.3 percent of requests — what next?
• Japanese LLM evaluation strategy if relevant to your product.

Score on judgment, risk awareness, and communication, not only code quality.

Step 5 — Compensation and HSP visa pre-package (week 4)

Have an offer template ready before the on-site. Components:

• Base JPY 14M-22M for senior IC.
• Annual target bonus 15-25 percent.
• Equity (scale-ups) or special allowance (large enterprises).
• Sign-on JPY 3M-6M plus relocation logistics for international.
• Highly Skilled Professional (HSP) visa pre-vetted documentation.
• Japanese language tutoring stipend (JPY 200K-500K per year).
• GPU cluster access: personal H100 or shared quota.

Compare with Singapore comp: nominal total is higher, but Tokyo wins on cost of living for senior IC roles, especially with HSP visa benefits.

Step 6 — Reference check by phone with 2 ex-managers (week 5)

Phone references, not Glassdoor. Ask 2 ex-direct managers about:

• Operational discipline during incidents.
• Japanese-language collaboration with stakeholders.
• On-call behavior and post-mortem culture.
• Ownership and initiative.

Step 7 — 90-day onboarding with V4-Pro stack (weeks 6-13)

A senior inference engineer should be operating semi-autonomously by day 75. Plan:

• Day 1-15: codebase tour, V4-Pro stack architecture, on-call shadow.
• Day 16-30: first incident scenario in simulation environment.
• Day 31-60: first production change ownership (small scope, supervised).
• Day 61-75: first solo deployment with rollback rehearsal.
• Day 76-90: review, calibration, Q3 target setting.

This onboarding cadence aligns with our DIFC and Singapore playbooks.

FAQ

How long does it take to hire a senior V4-Pro engineer in Tokyo?

Domestic candidate: 7-11 weeks. International with HSP visa: 10-16 weeks. SusHi Tech week candidates with HSP pre-package: 4-6 weeks.

What is a fair compensation package?

Senior IC: JPY 14M-22M base, 15-25 percent bonus, equity or special allowance. Sign-on JPY 3M-6M for relocation. Staff/principal: JPY 24M-34M total.

Should I prioritize Japanese-fluent or English-only candidates?

Depends on team language. English-only unlocks 4x larger candidate pool. Bilingual JP-EN: 12-15 percent premium, worth it for staff/principal stakeholder roles.

How does SusHi Tech 2026 affect my hiring strategy?

Set up booth or meeting room, fast-track interviews within 5 calendar days, pre-packaged offer templates ready by April 30. Companies that wait until May lose to faster competitors.
