When staff augmentation is appropriate

Augmentation can address a defined capacity or capability gap while technical ownership remains with the client organization.

The hiring challenge

Finding experienced mobile engineers in North America is hard. When you do find them, the process is slow:

  • 3-6 months to hire a senior mobile engineer
  • High salaries plus benefits, equity, and overhead
  • Risk of mis-hire after months of interviewing
  • Ramp-up time before they're productive
  • Difficult to scale down when the project ends
  • Competition for engineers with relevant production experience

Engagement characteristics

Embedded engagements are structured around:

  • Start within 1-2 weeks of agreement
  • Senior engineers with 8 to 15+ years mobile experience
  • Engineer profiles and client interviews before engagement
  • An onboarding period based on codebase access and complexity
  • Scale up or down as project needs change
  • North American time zones, Canadian rates, Canadian payroll

Case study · CLEIO

Embedded Android engineering for CLEIO

CLEIO is a Quebec neurotechnology company building EEG headset companion apps. They needed senior Android capacity to keep shipping while they evaluated a permanent hire. Hiring takes 3+ months, plus a ramp month. They didn't have that runway.

CLEIO engaged DEVSFLOW for embedded Android engineering. The work ran in the same repo, standups, and sprint cadence as their internal team. The first ticket started in week one, and delivery followed the client's cadence rather than a separate agency workflow.

The engagement used the client's existing technical ownership, review process, and delivery cadence.

“…a dependable, communicative, and professional consultant…integrated smoothly into the project team, ramped up on the project context efficiently, and consistently delivered against the cadence set by the client.”

Case study · Trackforce

Embedded into Trackforce's engineering team to ship critical fixes

Trackforce runs Tracktik, the mobile platform used daily by thousands of physical security guards across North America. They were facing revenue-impacting stability issues. Hiring permanent Android engineers fast enough wasn't an option. They needed senior capacity inside the existing team, immediately.

Under DEVSFLOW's staffing model, the engineers worked within Trackforce's repository, delivery process, and sprint cadence. They handled high-priority tickets through the stabilization cycle and completed a structured handover.

The engagement remained within Trackforce's existing engineering workflow through stabilization and handover.

“…for the work you've done resolving revenue-impacting issues from the Tracktik mobile app.”

Frequently asked questions

How is this different from a typical outsourcing agency?

Our engineers are full-time employees. DEVSFLOW handles employment and administrative support while the client retains day-to-day technical direction. If the role or fit is not appropriate, the agreement includes a replacement process.

Can I interview the engineer before they start?

Yes. We provide relevant engineer profiles, and clients may conduct a technical interview or pair-programming session before confirming an engagement.

What's the minimum engagement length?

We ask for a 3-month minimum to make the onboarding investment worthwhile for both sides. After that, it's month-to-month with 2 weeks notice to scale down.

Can I hire the engineer full-time after the engagement?

Yes, we offer a conversion path after 6 months of engagement. We'll work out a transition that's fair to everyone involved.

How quickly can an engineer start?

The typical target is one to two weeks from agreement, subject to engineer availability, client interviews, contracting, and access requirements.

Do you provide part-time engineers?

Yes. We offer both full-time (40 hours/week) and part-time (20 hours/week) engagement models. Part-time works well when you need specialized expertise but don't have a full-time workload.

What if the engineer isn't a good fit?

If the technical or working fit is not appropriate within the first two weeks, we provide a replacement at no additional cost under the engagement terms.

Who manages the engineer day-to-day?

You do. They report to your engineering lead or PM, attend your ceremonies, and follow your processes. We handle administrative/HR aspects and periodic check-ins to ensure satisfaction on both sides.
