At X-Team, we provide Mocha engineers who act like long-term teammates — designing test frameworks, integrating with your CI/CD pipelines, and ensuring quality so your JavaScript applications ship reliably.
Our hiring process pre-vets every candidate for JavaScript proficiency, Mocha framework knowledge, and cultural fit. We ensure only the most qualified and compatible QA engineers are presented for your consideration.
In many cases, we can match you with a single engineer within a few weeks. Larger teams take longer, depending on the skill sets and number of engineers required.
Yes. You can start with one Mocha engineer or ramp up a dedicated QA team, then adjust headcount up or down as your testing requirements evolve.
The cost to hire a Mocha test engineer varies by location, seniority, and engagement model. Typical hourly rates start around $37 per hour for mid-level talent, with market rates ranging up to $70–80 per hour for experienced engineers. Full-time Mocha engineers generally earn $80,000–$110,000 annually, aligning with general test-engineer salaries.
Freelance platforms can connect you with Mocha engineers, but you're on the hook for sourcing, vetting, and managing the work. X-Team is different. We provide you with fully committed, pre-vetted engineers who integrate into your stack, tools, and culture for the long haul.
You do, as long as payment is current. All test suites and configurations created by X-Team engineers are fully yours, protected under clean work-for-hire and IP assignment agreements.
X-Team engineers adopt your repositories, boards, frameworks, and rituals from day one—joining stand-ups, code reviews, and sprint planning just like any in-house teammate.
We'll resolve the issue quickly, whether through feedback or replacing the engineer. Our goal is long-term cultural fit, not just quick placement.
X-Team’s model is async-first, but we prioritize overlap with your core hours and match you with engineers who can collaborate in real time where it matters most.
Mocha engineers provided by X-Team follow your existing review and testing pipelines, use secure company-issued devices, and comply with best practices for credentials and access.
X-Team manages the full operational layer so you can scale globally without the legal or logistical friction. We handle onboarding, contracts, NDAs, and background checks. We ensure every developer is properly classified and compliant in their country of residence. You receive a single, simple invoice — no paperwork overload, no surprises.
We’ll sign an MSA that covers the terms of our work together. After that, our minimum engagement for a contracted scope of work is 3 months.
