After completing her B.Tech in Electrical Engineering from the University of Calicut in Kerala, she pursued a DRDO-sponsored M.Tech in Guided Missiles from the Institute of Armament Technology (now Defence Institute of Advanced Technology), Pune. Initially, she aspired to become an IAS officer. She even wrote the exam, but she got through the DRDO interview the same day and changed her trajectory. Thereafter, she obtained a PhD in Missile Guidance from Jawaharlal Nehru Technological University (JNTU), Hyderabad, Telangana, and an MBA in Operations Management from Indira Gandhi National Open University (IGNOU), New Delhi.

She started her career in the DRDO under Dr APJ Abdul Kalam’s stewardship in 1983. Tessy joined DRDO when it was not considered the domain of women, with only five women working in the organization. In 1986, she joined the Institute of Armament Technology (IAT), Pune (now Defence Institute of Advanced Technology) as a faculty member in Guided Missiles. In 1988, she joined the Defence Research & Development Laboratory (DRDL), Hyderabad. Thomas was a junior in the lab when Kalam took over as its director for a couple of years before moving on. At DRDO, from the beginning, she was associated with the ambitious project of developing the Agni Programme right from its developmental flights, contributing in various fields such as Guidance, Control, Inertial Navigation, Trajectory Simulation and Mission Design. She has designed the guidance scheme for long-range missile systems which is used in all Agni missiles. In 2001, she was conferred with Agni Award for Excellence in Self-Reliance. She spearheaded the project AGNI-4 as its Project Director, which displayed a number of new technologies and significant improvements in missile technology. Tessy Thomas with her team prepared and integrated the missile system and launched the missile successfully.
Thomas was also appointed as the project director of the 5,000 km range Agni-V, which was successfully tested on 19 April 2012. While serving as the Director of Advanced Systems Laboratory at DRDO, she held multi-dimensional roles and responsibilities, leading the development of a strategic missile system from 2014 to 2018. On 1 June 2018, she became Director General-Aeronautical Systems.
