iO Associates, Houston, Texas, United States, 77246
Senior Mechanical Engineer - Intervention Tools (Houston, TX)
We're engaged by a market-leading intervention tools manufacturer to hire a
Senior Mechanical Engineer
to lead design and qualification across a broad
well intervention
portfolio -
coiled tubing (CT) BHAs, slickline/wireline running & pulling tools, mechanical/hydraulic jars, disconnects, stroking tools, fishing/overshots, milling & cleanout tools, jetting/nozzles, e-line interfaces, and remedial/thru-tubing systems . You'll take concepts from whiteboard to field trial, balancing robustness, reliability, and rapid manufacturability. What you'll do
Own end-to-end mechanical design: requirements capture, concept trade studies, detailed design, prototyping, verification/validation, and release.
Model dynamic loads and pressure-driven actuation for CT and wireline duty cycles; perform fatigue, impact, torsion, and flow/erosion analyses (hand calcs + FEA/CFD).
Develop and execute qualification plans: pressure/burst/collapse, torque/tension, jar impact energy, sealability, erosion, vibration, and thermal cycling - incl.
HP/HT and sour service .
Select materials, heat treatments, coatings, elastomers, and springs for high-cycle and corrosive environments; author BoMs, drawings, routings, and test procedures.
Lead DFM/DFA with machine shops and suppliers (tight-tolerance rotating assemblies, threaded connections, sealing stacks).
Run structured reviews (FMEA, HAZOP), root-cause field failures, and implement design for reliability.
Mentor junior engineers; support shop builds, FAT/SIT, and occasional
rig-site trials .
What you'll bring
BS/MS in Mechanical Engineering
(or related).
7-12+ years
in mechanical design of
intervention tools
(coiled tubing, slickline, wireline/e-line, fishing/milling, disconnects/jars, stroking tools, cleanout BHAs, etc.).
Proficiency with
SolidWorks or Inventor ,
ANSYS (or similar FEA) ; strong GD&T per
ASME Y14.5 .
Demonstrated success qualifying tools for
HP/HT and H₂S (ISO 15156/NACE MR0175) ; deep knowledge of high-strength alloys, Ni-based materials, and elastomer compatibility.
Hands-on test rig experience and a data-driven approach to fatigue life and reliability.
Clear communicator comfortable with cross-functional teams and field personnel.
Nice to have
Experience with
pressure-control equipment interfaces
(CT BOPs, lubricators) and e-line service connections.
CFD for nozzle/cleanout optimization; experience mitigating erosion and debris ingestion.
Knowledge of
API Q1/Q2
quality systems, gated NPI, PPAP, and supplier qualification.
Familiarity with dissolvables, metal-to-metal seals, and non-explosive actuation.
Exposure to digital telemetry/tractor interfaces and toolstring shock/vibration mitigation.
Why join
Ship rugged tools that see immediate field impact across land and offshore interventions.
Empowered, fast-cycle engineering culture with ownership from concept to commercial launch.
Competitive base + bonus, strong benefits, and growth path to
Lead/Principal
or
People Manager .
Relocation to
Houston
available for exceptional candidates.
Location & work setup
Houston, TX (onsite hybrid).
Eligibility
US work authorization required - No sponsorship avaliable
