The posting, as the company wrote it
Employment: Full-time
Experience: Associate
Education: Bachelor's Degree
Join our dynamic team as a Senior Planner/Buyer. You'll play a key role in building our foundation, working with cutting-edge technologies, and supporting new product development. This position is ideal for a self-starter who thrives in a fast-paced, engineering-driven environment and enjoys working closely with technical teams to ensure material readiness for complex products. You will execute planning and procurement activities that support rapid product iteration, evolving Bills of Materials (BOMs), and demanding technical requirements. This role is an experienced individual contributor position with significant cross-functional exposure. Your key responsibilities are as follows:
Develop and maintain material requirements plans (MRP) to support engineering builds, prototype development, and low-rate production. Partner closely with Engineering to manage BOM releases, revisions, and Engineering Change Orders (ECOs).
Execute procurement against the Master Production Schedule (MPS) and ensure materials are aligned to cost, schedule, and performance objectives. Collaborate with Engineering, Quality, Program Management, and Finance to ensure material alignment with program milestones.
Monitor and manage long-lead-time components to prevent schedule risk. Proactively identify alternate parts or suppliers for long-lead or at-risk components.
Track and report key supply chain metrics, including OTIF, supplier lead times, purchase price variance (PPV), inventory accuracy, and material availability.
Maintain accurate planning parameters (lead times, safety stock, order policies) within the ERP system.
Identify, qualify, and manage suppliers capable of meeting technical specifications and quality requirements.
Lead RFQs, perform cost analysis, and negotiate pricing, terms, and delivery schedules.
Establish and manage supplier relationships to ensure on-time, quality performance.
Requirements
This position requires access to export-controlled information. Employment is contingent upon the applicant being a U.S. person as defined by 8 U.S.C. § 1324b(a)(3).
Experience:
Bachelor’s degree in Supply Chain, Engineering, Business, or related field; or equivalent experience.
5–8 years of experience in production planning, procurement, or planner/buyer roles.
Experience supporting new product introduction (NPI) or low-volume, high-mix manufacturing environments.
Experience in high-tech hardware sectors such as photonics, electronics, aerospace, or precision manufacturing preferred.
Skills:
Ability to read and interpret technical drawings and specifications.
Strong ERP/MRP system experience; advanced Excel skills required.
Familiarity with demand planning, MRP logic, and inventory control principles.
Understanding of supplier negotiations, RFQs, and basic contract terms.
Working knowledge of ISO9001 or AS9100 environments preferred.
Strong organizational skills with the ability to manage multiple priorities in a dynamic environment.
Startup Mindset:
You're creative, flexible, and eager to wear multiple hats.
You're passionate about building systems from the ground up and comfortable with ambiguity and change.
