Ashish Ranjan.
Some people appear to walk naturally into the spotlight, making it seem as though they were always destined to achieve exceptional things. But a closer look at their journeys often reveals a fair share of challenges, difficult choices, and persistent effort. One such example is Ashish Ranjan. He graduated in Mechanical Engineering as a university medalist with a GPA of 9.57 out of 10. His first job after college was in India's nuclear program under the Department of Atomic Energy. After qualifying through the competitive national-level screening process conducted by the Bhabha Atomic Research Centre, he entered the BARC Training School, the official training program of the Department of Atomic Energy in nuclear science and engineering. Completing this program led him to the highly sought-after position of Scientific Officer in India's nuclear program.
However, Ashish's passion rested in India's space program and the Indian Space Research Organisation. In 2018, the young engineer qualified through ISRO's highly competitive entrance examination and stringent interview process, securing All India Rank 4. At ISRO, he began contributing to space technology through his work on the Vikas engine, a liquid-propulsion rocket engine that uses earth-storable propellants. Ashish worked on several ISRO missions, with key responsibilities involving the assembly, integration, testing, and reliable functioning of Vikas engines used in the lower stages of major launch vehicles such as the PSLV, GSLV, and LVM3. He worked closely on the assembly, integration, and flight readiness of the engine associated with PSLV-C46, which successfully launched RISAT-2B, a 615-kilogram radar-imaging Earth-observation satellite, into an orbit approximately 555 kilometers above Earth. Unlike an ordinary optical camera, radar imaging can collect useful observations independently of daylight and is less restricted by cloud cover. Such Earth-observation capabilities support crop and land monitoring, forest assessment, and the rapid observation of areas affected by floods, cyclones, and other natural disasters.
Ashish further served in an important engineering role at the ISRO Propulsion Complex testing facility, where he worked on the ground hot-fire testing and flight-readiness validation of High-Thrust Vikas liquid rocket engines at the Principal Test Stand. The Vikas engine is a foundational propulsion system used across ISRO's principal launch vehicles, while the High-Thrust Vikas represented a significant improvement over the earlier engine configuration. Its combustion-chamber pressure was increased from approximately 58 bar to 62 bar, generating nearly six percent greater thrust. Before an engine could be approved for integration into a launch vehicle, it was required to undergo a controlled hot-fire test at the Principal Test Stand. These tests replicated actual engine-operating conditions and verified engine performance, combustion stability, thrust regulation, mixture-ratio control, thermal behavior, and the integrity of both the propulsion system and the test facility. Mr. Ranjan participated in multiple High-Thrust Vikas engine tests and was responsible for leading test preparation activities, verifying system readiness, monitoring engine and facility parameters in real time, evaluating performance, and contributing to post-test engineering analysis. What made these responsibilities particularly notable was that Ashish was only 25 years old at the time.
The next stage of his career took him to the United States, where he earned a master's degree in Mechanical Engineering from the University of California, Riverside. Although Ashish received a Dean's Scholarship to pursue a Ph.D. in Mechanical Engineering, he decided instead to strengthen and broaden his experience by applying his skills in the automotive industry. He later joined Lucid Motors, an electric-vehicle startup known for its industry-leading EV powertrain technology. At Lucid, he worked on vehicle architecture and helped address the complex engineering challenges involved in making next-generation electric vehicles production-ready. After further broadening his engineering skills by gaining experience in the automotive industry, Ashish went on to establish his own technology company, Raste, which has developed a platform that monitors vehicle health using operating telemetry data. The technology has the potential to change how individual vehicle owners and commercial fleets approach maintenance by transforming raw vehicle data into understandable and actionable information.
Raste has begun demonstrating its value to its early customers, particularly high-mileage users such as rideshare drivers and last-mile delivery fleets, for whom unexpected vehicle problems and downtime can directly affect their income and operations. Led by Ashish Ranjan as Chief Technology Officer, the Raste team aims to reduce vehicle owners' annual maintenance and breakdown-related expenses by as much as 40 percent by identifying developing problems early and helping users make more informed maintenance decisions. From nuclear engineering to aerospace, automotive development, and now a startup focused on improving maintenance efficiency and detecting vehicle issues before they become expensive breakdowns, Ashish's career is a strong example of continuous growth. It also demonstrates how skills developed across different industries can come together to create technologies that improve efficiency, reliability, safety, and sustainability.
