Who we are
A Bulgarian engineering company built by people who have run engineering companies
ECS.SDX provides software, hardware and mechanical design, development and testing. The team was assembled over twenty-five years across automotive, communications and consumer electronics, and averages more than fifteen years of experience per engineer.
Product level, not task level
We take a product from Request For Quotation to Start Of Production, including production support and model-year updates — not a stream of isolated tickets.
Teams that have already done it
Every engineer has years behind them at global corporations known for quality. The core team has worked together for more than fifteen years.
Commitments we keep
Our culture is close to a family one. Care for the customer, quality, and honouring what we agreed come first — in that order, every time.
Services
Complete product engineering, or the one discipline you are missing
We can own a product end to end, or plug a single team into an existing programme. Both are normal for us.
Software & Systems
Embedded and application software, system architecture and requirements engineering for automotive controllers — from bare-metal drivers and AUTOSAR stacks to Linux-based infotainment and in-house AI.
ExploreHardware
Automotive-grade electronics from architecture and power tree through schematic, worst-case analysis and EMC support, to plant industrialisation and post-SOP field analysis.
ExploreMechanical
Requirements-driven mechanical architecture, detailed 3D and 2D design, structural and thermal simulation, and validation through to supplier process capability.
ExploreVerification & Validation
Test architecture designed for reuse across platform and customer projects, the benches and simulation to run it, and coverage against ASPICE, ISO 26262 and NCAP.
ExploreSecurity & Safety
Security management, TARA and secure implementation for connected vehicles, alongside ISO 26262 functional safety work from concept through FMEA to verified implementation.
ExploreProgramme & Quality
Full-cycle steering of product programmes in classic and scaled-agile setups, with delivery responsibility, plus the quality function that automotive customers audit.

How we work together
From a five-person feature team to a hundred-plus engineer programme
The engagement is sized to the problem, and the commercial model follows the certainty of the scope.
5–10 engineers
Feature team
A focused squad owning a feature or supporting an existing product line.
20–50 engineers
Project team
End-to-end delivery of a medium-sized project with its own steering and quality function.
100+ engineers
Programme
Large multi-variant programmes run from RFQ through SOP and model-year updates.
Fixed price or T&M
Commercial terms
Flexible contracting: fixed price for defined scope, time and material for evolving work.
