Job description

An established engineering organization serving the industrial water and wastewater treatment sector is seeking a Senior Process Engineer to lead the development, implementation, and optimization of engineered treatment systems. This opportunity is suited to an experienced process engineering professional who can independently translate complex treatment requirements into practical, technically sound solutions. The position offers substantial ownership across the project lifecycle, from initial process design and engineering analysis through field implementation, commissioning, and ongoing system optimization.

Professional Responsibility and Scope

The Senior Process Engineer will take technical ownership of process design decisions, evaluating customer requirements, water chemistry, flow characteristics, and treatment objectives to develop effective system configurations. The role requires strong analytical judgment in process calculations, mass balances, equipment selection, system sizing, and performance evaluation. The successful candidate will independently identify and resolve complex technical challenges, balancing treatment effectiveness, operational reliability, capital requirements, and long‑term system performance. Responsibilities also include contributing to process flow diagrams, piping and instrumentation diagrams, engineering documentation, project estimates, and design standards. The engineer will support system startup, commissioning, field troubleshooting, and performance validation while working directly with customers and cross‑functional project teams.

Location and Lifestyle Context

The position offers the potential for flexibility in work arrangements, depending on the candidate's experience, location, and project requirements. Some travel will be necessary to support customer engagements, system implementation, commissioning, and technical troubleshooting. This is an opportunity for an engineer who values a combination of focused technical work, customer interaction, and practical field experience. Specific location and working arrangement details will be discussed confidentially during the recruitment process.

Long-Term Professional Growth

This role provides an opportunity to deepen technical expertise while expanding influence over engineering decisions, project execution, and system performance. The Senior Process Engineer will contribute to increasingly complex applications, establish repeatable engineering practices, and help strengthen the technical capabilities of other engineers. Over time, the position can support broader technical leadership, increased project responsibility, and greater involvement in evaluating engineering approaches and improving system design methods.

Compensation

The anticipated base salary range for this opportunity is $150,000 to $220,000, depending on relevant experience, technical expertise, and overall qualifications. Additional compensation may include performance-based incentives, subject to the applicable compensation structure. Benefits and other employment details will be discussed confidentially during the recruitment process.

Team Environment and Leadership Approach

The engineer will collaborate with professionals across engineering, project management, and customer-facing functions to develop solutions that meet technical and commercial requirements. The environment favors sound engineering judgment, direct communication, accountability, and practical problem solving. The successful candidate will be comfortable taking ownership of technical decisions while remaining engaged with colleagues, customers, and project stakeholders. Sharing knowledge, supporting developing engineers, and contributing to consistent engineering practices will be important aspects of the role.

Organizational Stability and Industry Position

The organization operates in the industrial water and wastewater treatment market, where customers rely on engineered systems to address demanding process requirements and maintain dependable operations. The position offers exposure to a range of industrial applications and opportunities to contribute to projects that require specialized engineering knowledge, effective implementation, and ongoing performance improvement. Candidates can expect work centered on practical engineering outcomes and the continuing need for effective water and wastewater management solutions.

Experience and Qualification Summary

Qualified candidates will bring substantial experience in industrial water or wastewater treatment, supported by a strong foundation in process engineering and treatment system design. Approximately eight to ten years of relevant experience is preferred, along with the ability to develop process designs independently and make informed decisions about system operation. Candidates should demonstrate a thorough understanding of water chemistry and treatment processes, with practical capability in flow calculations, mass balances, equipment sizing, technical troubleshooting, commissioning, and field performance evaluation. Experience working directly with customers and managing technical responsibilities in a fast-paced project environment is important. A bachelor's degree in Chemical Engineering or a related engineering discipline is preferred, as is familiarity with process flow diagrams, piping and instrumentation diagrams, project estimating, equipment costing, and budgeting.
