Injection Molding Process Engineer

About the role

This role leads and optimizes injection molding operations for a global precision plastics team. The position provides technical leadership for molding systems and equipment in Fort Worth. Success in this role requires a mechanical engineering background and comfort with fast-paced, precision-driven environments.

Software engineers turn product ideas into working code. Engineers work in small teams, review each other's work, and ship in small batches. Most teams follow agile practices such as sprints and daily standups. Engineers also write tests, fix bugs, and improve performance. The field values clear communication as much as technical skill. Engineers spend part of every week on planning, code review, and debugging, not just writing new code. The ability to explain a technical decision in plain words separates strong engineers from the rest.

Key facts

What you'll do

Machinery and equipment are tested and developed under engineering direction to validate performance.

Process adjustments, new tool introduction, test runs, molding procedures, and machine conversions are standardized to drive consistency.

Communication expectations are standardized, including startup notifications and issue tracking, to align cross-functional workflows.

Production priorities and scheduling are determined with shift leads to balance throughput and operational constraints.

Requirements

A Bachelor's degree in mechanical engineering is held as a baseline qualification for the role.

Experience with lot number traceability, engineering-grade resins, and specification-driven processes is demonstrated to ensure quality compliance.

Expertise in injection molding equipment, including specifying, upgrading, repairing, and maintaining core systems and tooling, is shown.

The ability to develop and implement preventative maintenance (PM) programs is used to reduce unplanned downtime and support reliability.

Knowledge of auxiliary equipment such as mold water/oil heaters, hot manifold systems, screws, barrels, ceramic heater bands, material drying and conveying systems, and dew-point meters is applied to optimize process stability.

Troubleshooting, documentation, and communication skills convey technical findings to diverse stakeholders.

A safety-first mindset and collaborative approach is used to work with teams and partners across operations.

Nice to have

Experience in STEM outreach and community engagement initiatives that connect technical work with broader audiences.

Practical notes

Typical interview steps

Hiring for engineering roles usually starts with a recruiter screen, followed by one or two technical rounds. Candidates often solve a coding problem, discuss past projects, and answer system design questions. Some loops include a take-home task. Final rounds typically cover team fit and give candidates a chance to ask questions. Interviewers look for how you break down an unfamiliar problem, not just whether you reach the answer. Practicing a few problems aloud and reviewing your own past projects are the best preparation.

Good to know

Injection molding is a core plastics manufacturing process that relies on precise control of temperature, pressure, and timing.

Mechanical engineers often use CAD tools, simulation software, and data analysis to guide process improvements.

Process optimization in manufacturing focuses on quality, cycle time, and equipment reliability.

Technical documentation and clear communication are essential for coordinating with production and engineering teams.

Continuous improvement methods help teams reduce waste and enhance throughput in production environments.

Career growth

Engineering careers usually progress from individual contributor to senior, staff, and principal levels. Some engineers move into management and lead teams of five to twenty people. Others stay on the technical track. Growth follows demonstrated impact, not tenure alone. A typical engineering ladder has clear levels with defined expectations for scope, quality, and mentorship. Moving up usually requires owning outcomes end to end rather than completing assigned tickets.
