Senior Engineering
Senior engineers who work inside your day.
When the need really is capacity and you already have delivery leadership, Sonatafy provides individual senior engineers from the US or Latin America, working in your business hours and integrated with your team.
Our approach
Capacity, when capacity is the answer.
More engineers isn't always the answer. When delivery accountability is in question, we recommend a Managed Delivery POD instead.
When your delivery leadership is in place and the constraint really is capacity, senior engineers integrate directly into your teams, workflows, and standards. Sonatafy does not place junior engineers on client engagements.

FAQ
Senior Engineering FAQs
Individual senior engineers from the US or Latin America who integrate into your existing team. It fits companies that already have delivery leadership and need engineering capacity, not delivery accountability.
Senior Engineering is Sonatafy's version of staff augmentation, with senior engineers only. The difference from a Managed Delivery POD is ownership: with Senior Engineering, your leadership owns delivery. When delivery accountability is in question, we recommend a POD.
Sonatafy does not place junior engineers on client engagements. Client-facing engineers are hired to a senior experience standard, generally 8 to 10+ years of production software engineering, and each engineer's background is shared with you before approval.
Yes. You interview candidates and have final approval on every engineer placed on your account. Sonatafy will not place an engineer over your objection.
Our target is 30 days or less from an approved role specification to start date. Highly specialized roles or extended interview cycles can take longer, and we share the projected timeline at role intake.
Senior engineers are based in the US and Latin America, including Mexico, Colombia, Argentina, Costa Rica, and Brazil, and work during US business hours.
Every Sonatafy team member is tested for English proficiency through live conversational interviews and technical discussions. The bar for client-facing engineers is fluent professional communication suitable for daily work in US-based engineering teams.
You do. The client owns 100% of all code, designs, documentation, and other work product created under the engagement, and source code stays in your repository.
No. Sonatafy engineers remain full time Sonatafy team members throughout the engagement, which protects delivery continuity.
Fee and scope are set in a scoping conversation. Snapshots are complimentary if you want a senior read on whether capacity is really the constraint.
