You can find App developers on job boards like Indeed, Glassdoor, and professional social networks like LinkedIn. Freelance platforms are another great place to look—post your job description or find specialists open to new opportunities there. Networking events, tech meetups, and conferences are fantastic for meeting talented engineers in person.

Can I test the developer skills during the no-risk trial period?

Yes, you can test the developer skills during the extended evaluation period, typically of up to 20 paid hours. Besides, you are welcome to assign tasks or arrange an interview. If the fit isn’t right, we’ll promptly find a replacement. No stress, no hassle. For this, open a dispute in your account via the “Report a problem” button. We’ll assign your project to another App developer or issue a refund within 40 hours

Are App developers in demand?

Yes, App developers are in demand. Businesses invest in App development to engage customers or equip their staff with flexible tools. That’s why skilled engineers are more sought after than ever. To be more specific, these jobs are expected to grow 25 percent by 2031, according to industry projections. Bringing on top talent now sets your business up for long-term success and a strong market presence.

How quickly can I hire an App developer through Lemon.io?

You can hire an App developer through Lemon.io in 24 to 48 hours. Generally, it depends on how quickly you pick among the offered candidates and whether you decide to interview them. From our side, we ensure a quick turnaround time.

The entire hiring process looks like this. You tell us what you’re looking for in a candidate and review the CVs we provide. We’ve already vetted these specialists, but if you want to interview them yourself, feel free to do so. Once you make your decision, we sign an agreement. After this, your expert is ready to start.

What is the vetting process for developers at Lemon.io?

Developers at Lemon.io have four stages of vetting.
1. There is pre-screening. The candidate fills out the profile, and the system selects only those with relevant experience, tech stack, English level, and location.
2. Our recruiters hand-check CVs, LinkedIn profiles, and other open sources that may hint about the engineer’s professional background. We look for devs with a proven track record and experience in remote work.
3. Next comes a friendly call with HR. In English, of course. They make up their mind about how it may feel working with you and conduct a technical screening via Coderbyte.
4. Hard skills interviews and live coding tasks are the final stage of our vetting flow.

If a candidate fails any stage, even the last one, we don’t hire them. We’re committed to bringing only the best talent to our platform.

Why should I use Lemon.io for hiring developers?

You should use Lemon.io to hire developers because this saves you time. We are so good at this that 70% of our customers hire the first candidate we offer, and another 20% choose the second one. We emphasize vetting, so you get top-tier talent, not just anyone with a keyboard. Plus, our prices are affordable because we hire most developers from Eastern Europe. But no worries. There is a vast talent pool for any location, budget, and project scope. We also support our clients throughout the entire working process. You won’t be left hanging once you’ve hired your specialist.

How much does it cost to hire an App developer?

The cost of hiring an App developer involves the salary itself, which ranges from $69K to $110K for junior developers and goes up to $215K for lead mobile engineers in the USA. Then, you have recruitment costs: job postings, recruitment agencies, and interview processes. There are benefits and perks to think about. Health insurance, retirement plans, or paid time off increase the total cost. Once you hire someone, you need to invest in onboarding and training. Don’t forget about laptops, software licenses, and other tech resources.

Hiring with Lemon.io is more cost-effective because we handle most of these additional expenses. We find and vet top global talent, so there are candidates for any budget, time zone, and project specifications.

How are Lemon.io App developers different?

Lemon.io App developers are different because they make only the top 1% of talent from over 500 job boards. Before joining our pool, they undergo a multi-faceted screening. This means you get specialists who are technically proficient, great communicators, and team players Also, misunderstanding is unlikely to be an issue since we check English proficiency. Our devs have an average of seven years of experience, so they’re ready to tackle any project.
