Senior Mechanical Engineer - MWD/LWD/RSS (Houston, TX)We''re partnering with a top-tier drilling technology company to hire a Senior Mechanical Engineer to lead design and qualification of MWD/LWD tools and Rotary Steerable Systems (RSS). You''ll own ruggedized mechanical architectures for HP/HT drilling environments - delivering reliability under shock, vibration, and high rotational speeds while meeting tight packaging constraints around sensitive electronics and sensors.What you''ll doLead end-to-end design for MWD/LWD subs, mud-pulse/EM telemetry modules, sondes, sensor housings, and RSS actuation/mechanisms (push-the-bit / point-the-bit).Perform structural, fatigue, thermal, and dynamic analysis (rotor-bearing systems, rotary bending, stick-slip/whirl, bit bounce) and correlate with lab/field data.Engineer pressure housings, feedthroughs, hermetic sealing, potting/encapsulation, vibration isolation, and thermal paths for electronics in (Apply online only) C and 20k+ psi service.Design flow control valves, bypass/dump valves, turbines/PDM interfaces, high-speed bearings and seals, and wear/erosion-resistant features for drilling fluids.Create drawings/BOMs, GDandT (ASME Y14.5), test plans, and design dossiers; lead FMEA/DFR and cross-functional reviews.Support assembly/FAT/SIT, root-cause field issues, and mentor junior engineers.What you''ll bringBS/MS in Mechanical Engineering (or related).7-12+ years designing MWD/LWD or RSS hardware (sensor collars, telemetry tools, s
