Senior Mechanical Design Engineer - Completion Tools

Senior Mechanical Engineer - Completion Tools (Houston, TX)

We're partnering with a leading completions manufacturer to hire a Senior Mechanical Engineer

to own new product design and sustaining engineering across a mature and growing

completion tools

portfolio (e.g.,

packers, plugs, frac sleeves, liner hangers, cementing/float equipment, and sand control tools

). You'll be the technical driver from concept to commercialization - balancing reliability in HP/HT and sour environments with manufacturability and cost.

What you'll do

- Lead end-to-end mechanical design for downhole completion tools: requirements, concept generation, detailed design, prototyping, validation, and launch.

- Run advanced analysis (stress/fatigue/thermal) and verification using FEA and classical hand-calcs; correlate models with test data.

- Define and execute qualification test plans (pressure/burst/collapse, torque & tensile, sealability, flow/erosion, thermal cycling) including HP/HT and sour service testing.

- Apply

API/ISO

and company standards (e.g., API 11D1, API 19 series, ISO 15156/NACE MR0175) and author engineering documentation, BoMs, and design dossiers.

- Drive DFM/DFA with Manufacturing & Supply Chain; select materials/coatings/elastomers for harsh service.

- Lead design reviews, mentor junior engineers, and provide field deployment/forensics support as needed.

- Partner with Product Line, Reliability, and Quality to deliver on cost, performance, and schedule.

What you'll bring

- BS/MS in Mechanical Engineering

(or related).

- 7-12+ years

of mechanical design experience with

completion tools

(any major product line from OEMs or service companies-packers/plugs/liner hangers/frac sleeves/etc.).

- Proficiency in

SolidWorks or Inventor

,

ANSYS (or equivalent FEA)

, and GD&T per ASME Y14.5.

- Demonstrated success qualifying tools for

HP/HT

and

sour

environments; strong materials & elastomer knowledge.

- Hands-on test/rig experience and a data-driven approach to failure analysis and reliability improvement.

- Clear, concise communicator who can influence cross-functionally and mentor others.

Nice to have

- Knowledge of additive/manufacturing automation, hardfacing, and wear/erosion mitigation.

- Exposure to wireline/coiled tubing deployment or sand control screens.

- Familiarity with downhole hydraulics and sealing mechanics.

Why join

- High-impact role shaping a flagship completions portfolio used globally.

- Lean, empowered engineering culture with real ownership from concept to field.

- Competitive base + bonus, strong benefits, and growth path to Lead/Manager or Principal Engineer.

- Relocation support to Houston available for the right candidate.

Location & work setup

- Houston, TX (onsite hybrid).

Occasional shop/field and test lab time expected; limited travel for trials and customer support.

Eligibility

- US work authorization needed - No Sponsorship offered
