A Materials Science Engineer studies and develops materials to improve their performance, durability, and efficiency in various applications. They work with metals, ceramics, polymers, and composites to create new materials or enhance existing ones for industries such as aerospace, automotive, healthcare, and electronics. Their work involves research, testing, and developing manufacturing processes to ensure materials meet required standards. They collaborate with scientists, engineers, and manufacturers to solve material-related challenges.
To thrive as a Materials Science Engineer, you need a strong grasp of materials characterization, thermodynamics, and engineering principles, typically supported by a degree in materials science, chemistry, or a related field. Familiarity with lab testing equipment, materials modeling software, and certifications such as Six Sigma or Lean Manufacturing can be highly valuable. Effective teamwork, problem-solving, and clear communication skills enable you to collaborate across disciplines and convey complex findings. These abilities are crucial for driving innovation, ensuring product quality, and meeting project goals in materials development and engineering environments.
Materials Science Engineers often encounter challenges such as optimizing material properties for specific applications, troubleshooting manufacturing defects, and staying current with rapidly evolving material technologies. They may need to balance theoretical research with practical implementation, all while ensuring compliance with industry standards and project deadlines. Working in this role often involves close collaboration with product designers, engineers, and production teams to integrate new materials into existing or novel products. Overcoming these challenges requires both technical expertise and the ability to communicate complex information effectively within multidisciplinary teams.

About Ceres Caribe
Ceres Caribe was founded in Puerto Rico in 1998 after Hurricane Georges. It has since grown to be one of the largest employers by providing careers on the island. Ceres Caribe is recognized for its rapid disaster recovery including debris removal, demolition, and blue roofs. We perform resiliency services, including vegetation management and utility line clearing for the Puerto Rican power grid. Ceres Caribe is also nationally recognized for creating natural parks and an aviary center on the island. The company is expanding its efforts to assist in securing the power grid for the Island.
Driven by Purpose, Powered by People
At Ceres Caribe, we believe you're more than just an employee; you're part of a team with a purpose and a meaningful mission. Whether in management, field operations, or behind the scenes, every team member plays a vital role in restoring hope, helping communities recover and rebuild.
We value initiative, respect diversity, and give our people the freedom to lead. We offer competitive pay, travel opportunities, and a culture built on resilience and teamwork. If you show up with compassion, share the commitment, react with urgency, and deliver solutions, you'll fit right in. We don't just respond to challenges; we rise to them.
What We Are Looking For
We are seeking a highly skilled Project Engineer with a proven background in civil construction and project management to oversee day-to-day activities on one or more construction sites. This role ensures projects progress on schedule while adhering to contract specifications, contributing directly to the reliability and sustainability of Puerto Rico’s power generation and resiliency infrastructure.
The Project Engineer fits within the operations team, reporting to the Project Manager, and may provide work direction to junior engineering staff or contractors as needed, though it does not involve full people management.
Success in the first 12 months looks like effectively managing site activities to meet budgets and timelines, building strong partnerships with clients and teams, resolving on-site issues proactively, and delivering high-quality results on at least one major project phase, while demonstrating compliance with safety and quality standards.

What to Expect
As a Project Engineer at Ceres Caribe, expect a dynamic, hands-on role where you’ll oversee daily operations on civil construction sites focused on power generation and resiliency infrastructure across Puerto Rico. You’ll start your day with site inspections, coordinating with teams and contractors to ensure smooth progress on tasks like concrete pouring, pipe installations, and earthworks. Mornings may involve analyzing progress against budgets using tools like HeavyJob-HCSS and MS Project, followed by updating blueprints and preparing pay estimates.
Afternoons often shift to problem-solving—resolving resource shortages, conducting feasibility studies, or implementing technology solutions—while maintaining safety protocols and quality controls, such as density tests and SWPPP reports.
The work environment is primarily outdoors on job sites, exposed to weather, dust, noise, and mechanical parts, requiring long hours (including weekends) and occasional overnight travel locally or nationally. Schedules are project-driven, often 10–12 hour days to meet deadlines, with a focus on urgency and teamwork. You’ll collaborate closely with clients, junior staff (whom you may train), and external partners, building relationships that drive project success.
Challenges include adapting to variable site conditions and tight timelines, but success means delivering on-time, on-budget projects that enhance Puerto Rico’s energy resilience and community recovery.
