Working with an engineering team in Brazil: time zones, language, NDAs and file security

Nearshore engineering usually means Mexico or Eastern Europe. Brazil is less obvious and, for many teams, a better fit: a large base of mechanical engineers, a time zone close to both North America and Europe, and a manufacturing industry that uses the same CAD tools and standards. Here is what working with a team in São Paulo looks like in practice.

Time zones: the real overlap

São Paulo is UTC−3 all year; Brazil ended daylight saving time in 2019. So the difference to you changes when your clocks change.

You are in	Winter (your standard time)	Summer (your DST)	What it means
New York, Toronto (Eastern)	São Paulo +2 h	+1 h	Almost the same working day
Chicago, Houston (Central)	+3 h	+2 h	Same working day; Brazil starts earlier
London, Dublin	−3 h	−4 h	Your afternoon is their morning
Amsterdam, Stuttgart (CET)	−4 h	−5 h	Handover at the end of your day

For US teams: questions get answered during your shift. For European teams: use the overlap in your afternoon for questions, and send revisions at the end of your day for the next morning.

Language

Work in English: emails, drawings, notes and meetings. Brazilian engineers who serve international clients are used to it. Ask for written answers to anything that affects a drawing; it removes ambiguity regardless of language.

Contracts and NDAs

• NDA first, before files. Use your template if you have one.
• Governing law and courts: state them. Many international clients choose their own jurisdiction; agree it explicitly.
• Ownership of deliverables on payment, written in the scope.
• Language of the contract: English is common; if a Portuguese version exists, say which one prevails.

Data protection and file security

Brazil’s general data protection law (LGPD) covers personal data, such as names and emails of your team, and works in a way similar to the GDPR. Your drawings and models are usually not personal data; they are protected by the NDA and the contract. Agree in writing:

• which channel files travel through (your SharePoint, Box, a PDM, or a link the supplier provides);
• who at the supplier has access;
• that files are not used for anything else, including training AI models;
• deletion at the end of the project on request.

If the data is export-controlled (ITAR, EAR, dual-use), check authorization before sending anything abroad.

Invoicing and payment

Agree in writing which currency you will be invoiced in, how payment is made (an international transfer is the usual route) and the payment terms, and put it in the scope. Fixed-price scopes make budgeting across currencies simpler.

How does the day-to-day work look?

A typical engagement settles into a simple rhythm:

When	What happens
Kick-off	Video call: scope, standards, template, who answers questions
Daily	Questions in a shared channel; answers in writing
Weekly	Short written status: done, in progress, blocked
Per package	Delivery, your review comments, one revision round, release

The time zone makes the daily part easy for US teams: questions asked in the morning in São Paulo reach you at the start of your day. For European teams, questions sent in the São Paulo morning arrive in your early afternoon, and you can answer before you leave.

Standards, units and software

Brazilian engineering practice follows ISO and ABNT standards and uses the metric system, but engineers who work for North American clients draw in inches and to ASME Y14.5 as a matter of routine. State the standard, the units and the CAD version in the scope, and send your template. The common CAD packages used in North America and Europe are used in Brazil too, so native file exchange is usually straightforward.

Communication habits that make it work

Distance amplifies ambiguity. A few habits remove most of it:

• one named contact on each side;
• decisions confirmed in writing, even after a call;
• marked-up PDFs for drawing comments instead of long email threads;
• questions numbered and answered by number.

None of this is specific to Brazil; it is how distributed engineering teams work well anywhere.

Costs and expectations

Outsourcing to Brazil is often chosen for cost, but the better reason is capacity in a compatible time zone. Judge a supplier by the clarity of their questions and the quality of the first package, not only by the rate. A cheaper drawing that needs three review rounds costs more than a correct one.

Holidays and planning

Brazil’s national holidays (and Carnival, which in practice closes many businesses for several days) do not match the US or European calendars, and neither do yours for the supplier. Ask for a project calendar with both sides’ holidays marked when a package crosses them, and plan releases around them the same way you would with any distributed team.

A practical start

Send one real drawing. The way a supplier handles the first review (questions asked, clarity of the scope, response time) tells you more than any sales call.
