How You Hire Front-end Developers from ScienceSoft

Initial Request

You send us a request, specifying the number of front-end developers you need, their desired level of their 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 name the CVs you're most interested in and let us know the time you're available for interviewing the candidates.


We help arrange the interviews with our front-end 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

Fast team adjustments on demand

When choosing ScienceSoft’s services by front-end developers in a dedicated or an augmented team, you get the necessary resources in less than a week and can expect us to add or remove FTEs on your demand in 1-2 days.

KPI-controlled progress

Latest technology knowledge

To keep our front-end developers’ skills ahead of the curve, we endorse active participation in relevant tech conferences & webinars and organize internal & external training sessions on the use of front-end development tools.

Hire Front-End Developers: In-house vs. Outsourcing

  • On average, it takes 8-10 months to find front-end developers (2-3 talents) with necessary skills and experience and get them onboard. Vendors already have a pool of cherry-picked talents, who will be ready to join your project in a week.
  • Handling payroll taxes is a natural consequence of in-house hiring. By working with a vendor, you have them handle all taxes while you only pay the service fee according to the T&M model by hourly rate.
  • Hiring front-end developers to your in-house team, you take on long-term legal responsibilities. Vendor outsourcing lets you easily put the cooperation on hold whenever you need it or cancel partnership with a 1-month notice.

Choose Your Cooperation Model

Hire front-end developer(s) from ScienceSoft to address skill deficiency or bridge staff gaps in your project.

Go for team augmentation

Entrust the front-end part of your web/mobile project to a team of experienced front-end talents managed by ScienceSoft’s Team Lead/PM.
