Hire A Senior React Developer — NYC, Onshore

Hiring Through NextGen vs Posting on a Job Board

The math on posting a Senior React Developer role directly on LinkedIn, Indeed, or Wellfound: 8–14 weeks of calendar time from posting to first productive week, roughly 120–200 inbound applications to filter, 15–25 first-round interviews for your engineering managers to run, and — for NYC financial and professional services firms — a 30–50% offer-decline rate against competing bulge-bracket, fintech, and Big Tech packages.

The math with NextGen: 2–3 candidate profiles delivered within 5 business days, you interview only pre-vetted engineers with signed availability, and the first productive week starts 10–14 days after signature. Zero recruiting overhead on your side, no job-description writing, no sourcing, no first-round screening burden. If the engagement is going well at month three, contract-to-hire converts to full-time for a fixed conversion fee.

Post on a job board when the role is permanent, budget for it is set for FY, and you have an in-house recruiter with capacity. Use NextGen when the work needs to start this quarter, the scope is well-defined but the permanent-headcount decision isn't, or your engineering managers cannot afford 40–60 hours of interview loop time this month.

Frequently asked questions

How are React developers vetted?

Every engineer clears four gates before they see a client codebase: (1) 60-minute technical screen with a senior engineer covering React internals (reconciliation, hooks rules, concurrent rendering), TypeScript, and modern tooling; (2) live coding round on a real component-composition and state-management problem — no take-homes, no leetcode; (3) system-design round on a frontend architecture problem (routing, data layer, auth boundaries); (4) reference calls with two prior engineering managers from the last 24 months. Fewer than 8% of applicants clear all four.

Do you offer contract-to-hire?

Yes. Standard structure: 3-month embedded contract at hourly rate, then a fixed conversion fee (typically 20% of annualized base) if you extend a full-time offer and the engineer accepts. No conversion fee at 12 months of engagement. We do not restrict engineers from taking direct offers — the fee covers our sourcing and vetting cost, not a non-compete.

What's the rate structure?

Senior React developers: $140–$185/hr depending on seniority band and engagement length. Staff/principal-level: $175–$225/hr. Monthly retainers available at a 10–15% discount against hourly for 6+ month commitments. Rates are all-in — no separate recruiting fee, no markup for benefits, no per-diem for NYC on-site days. Billed monthly against timesheets you approve.

Are engineers actually onshore?

Yes. Every engineer is US-based, works in Eastern or Central time, and is W-2 with NextGen or a long-term US contractor with a signed NDA and IP assignment. We publish city of residence for each candidate in the profile — most are NYC, Boston, Philadelphia, or NC/TN tech hubs. No offshore subcontracting, no rotating pools, no pass-throughs. This is written into the engagement contract.

What seniority level should we expect?

The typical placed engineer has 7–12 years of production React experience, has led at least one greenfield frontend build to launch, and has shipped in one or more of: financial-services trading UIs, healthcare provider tooling, legal or accounting SaaS, or B2B fintech. Junior and mid-level engineers are available on request but are not the default — most NYC firms we work with are hiring because they need judgment, not throughput.
