From Volume to Precision

Most hiring flows stop at keyword matching. Our AI hiring software evaluates capability—mapping applicants to role-aware checkpoints so only production-ready Web3 engineers make the shortlist.

How We Evaluate

Each applicant is scored 0–10 across six checkpoints calibrated for Web3 backend roles:

Checkpoint Score Distribution

This Marimekko-style chart summarizes 259 applicants by checkpoint and score band. Each column is a checkpoint; stacked colors show score brackets (0–2, 3–4, 5–7, 8–9, 10). Taller stacks mean more candidates scored at that checkpoint; more color at the top (8–10) means stronger proficiency.

What it reveals at a glance:

• Smart Contracts & Integration trend strong: Large 8–9 bands, with a meaningful top 10 slice—solid delivery depth on-chain and at the interface layer.
• Architecture is mid→upper band: Most candidates sit 5–9; truly senior (10) architects are scarcer.
• Security is the thinnest at the top: Lower bands (0–4) are sizeable, with relatively few 8–10 scorers—security remains a hiring gap.
• API & Data skew mid: Heavy 5–7 with fewer perfect 10s—competent, but fewer experts in data modeling and performance.
• Backend seniority is polarized: Noticeable presence in both lower and top bands—many developers, fewer seasoned platform engineers.

Top 10 Hands-On Skills

• Solidity — Core language for authoring secure, production smart contracts.
• Smart Contracts — Practical design, testing, deployment, and lifecycle management.
• Ethereum — Target network and tooling ecosystem for most dApps.
• Node.js — Runtime for APIs, indexers, and blockchain integration services.
• TypeScript — Type-safe code for reliability and maintainability at scale.
• Web3.js — Programmatic chain interactions: providers, wallets, events.
• Express.js — Lightweight framework to expose blockchain logic via APIs.
• MongoDB — Flexible off-chain storage for unstructured dApp data.
• PostgreSQL — Structured storage for analytics and transactional workloads.
• Hardhat — Testing, debugging, and deployment workflows for contracts.

Why It Matters

• Production over buzzwords: Shortlists center on engineers who can ship secure contracts and stable services.
• Fewer mis-hires: Role-aware scoring exposes gaps in security, testing, or backend rigor early.
• Time-to-value: Teams start faster with developers already fluent in the target stack.
