Cyient vs QuEST Global: overview
Cyient
Cyient was established in 1991 in Hyderabad, India as Infotech Enterprises Ltd and was rebranded to Cyient in 2014. The company delivers engineering services with particular strength in aerospace and defense, including embedded avionics systems such as fly-by-wire, actuation systems, collision avoidance, and autopilot controls, alongside a broader Design-Build-Maintain strategy that has included several acquisitions (including CERTON Software in the avionics software space) over the years. Cyient reports a workforce in the 12,000-15,000+ range across operations in India and the US, with embedded avionics as one specialization within a wider engineering services portfolio.
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, having grown into a large product engineering and lifecycle services company operating in more than 18 countries with over 90 delivery centers. The firm serves a very broad range of industries — aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors — with embedded engineering as one capability within end-to-end silicon and embedded engineering services offered to chipmakers and industrial clients. Reported employee counts vary substantially by source, from roughly 21,500 to over 32,000, reflecting the difficulty of pinning down an exact figure for a firm this size.
