How to Hire iOS Developers from ScienceSoft

Initial Request

You send us a request, specifying the number of iOS experts you need, their desired level of experience, as well as the model of cooperation you're interested in.

CV Scanning

ScienceSoft performs preliminary scanning of our experts' CVs in the database and sends you the most relevant ones.

Interview Scheduling

You choose the CVs you're most interested in and let us know the time you're available for interviewing candidates.


We help arrange the interviews with our iOS developers within 1-2 days.

SLA Preparation

After you confirm the experts' competence, ScienceSoft works with you to compose a service level agreement (SLA).


Once you sign, the experts (lead by ScienceSoft’s or your PM – you decide) immediately start working on your project.

How We Ensure Successful Cooperation

Smart resource allocation

A pool of experienced iOS developers allows us to provide the best candidates or assemble an outstanding self-managed team in 2 days -1 week. ScienceSoft guarantees fast team scale up/down and – in case of rare emergencies – risk-free staff replacement.

KPI-controlled progress and performance

ScienceSoft uses a well-established KPI-based reporting system to monitor the performance and productivity of its iOS developers. We share our metrics and reporting tools with customers to ensure 100% transparency of cooperation.

Employee motivation and growth

We provide our iOS developers with safe and comfortable working conditions, offer them various training opportunities for professional growth, and financially support Apple Developer Program certification. We encourage effective collaboration and continuous knowledge sharing on iOS projects.

Hire iOS Developers: In-house vs. Outsourcing

  • Assembling the right in-house team of iOS developers takes 8-10 months on average. Meanwhile, cooperation with a vendor gives you the necessary resources in under 1 week.
  • Your choice of talents is always limited if you hire in-house. Today’s online collaboration tools let you leverage the skills of professionals from all over the world, and vendors’ assistance in hiring talents make this option fast, cost-effective, and easy (legal-wise).
  • The differences in geolocation of outsourced developers usually create differences in their hourly rates, which can help you optimize the costs of an iOS development project.
