Job Description
Senior Process Engineer - Proposals and Bid Engineering
Department
Process and Proposal (P&P) Engineering
Reports to
Head - Process and Proposal Engineering
Location
Gurugram (Corporate HO), on-site, with travel to project and client sites as required
Role Purpose
The Senior Process Engineer is a senior individual contributor in the Process and Proposal Department, owning end-to-end process engineering for incoming RFQs, tenders, and pre-bid technical engagements across W.O.G.'s domestic and international pipeline. The role sits at the front end of the project lifecycle, converting client tender documents, raw water and wastewater characteristics, and discharge or reuse norms into technically compliant, commercially competitive, and bid-winning process solutions.
This is a high-visibility role with direct exposure to Business Development, Engineering, and Senior Leadership.
What This Role Is, and What It Is Not
This is a proposal and bid engineering role. The core of the job is solutioning and costing winning technical proposals against live tenders, not running plants.
This role IS for candidates whose recent and primary work is:
- Proposal / bid / tender / estimation engineering with an EPC, OEM, or system-integrator company.
- Front-end process design and technology selection for ETP / STP / WTP / ZLD / SWRO / MEE / MBR / UASB bids.
This role is NOT suitable for, and applications will not be progressed from, candidates whose primary experience is:
- Plant operations and maintenance (O&M), plant or process in-charge, or shift operations roles.
- Commissioning-only or site-execution-only profiles with no proposal ownership.
- Laboratory, water-chemistry, or quality-control roles.
- Academic, R&D, or product-development roles without a tendering track record.
Candidates from the above backgrounds who wish to move into proposals should not apply against this senior role; relevant junior openings, where available, will be advertised separately.
Must-Have Screening Criteria (all required)
An application must satisfy every point below to be shortlisted. These are non-negotiable and will be checked at CV stage.
- Engineering degree (B.E./B.Tech) in Chemical, Environmental, Mechanical, or Process Engineering.
- Minimum 10 years in water and wastewater process engineering, of which at least 4 to 5 years in a dedicated Proposal / Bid / Tendering / Estimation function with an EPC, OEM, or system integrator.
- Current or most recent job title clearly reflects proposals, bid, tender, estimation, or front-end process design (not O&M / plant in-charge / operations).
- Demonstrable ownership of submitted techno-commercial proposals across ETP / STP / WTP / ZLD / SWRO / MEE (candidate should be able to walk through specific bids at interview).
- Hands-on process and hydraulic sizing, mass and energy balance, and costing in Excel.
- Working knowledge of at least one membrane design tool: WAVE, IMSDesign, ROSA, Toraywater, or Winflows.
- Exposure to both industrial and municipal water / wastewater projects.
Key Responsibilities
A. Proposal Engineering and Bid Support (primary focus, about 60 percent)
- Lead the technical solutioning of incoming RFQs / RFPs / tenders for ETP, STP, WTP, SWRO desalination, ZLD, MEE/MVR, reuse and recycle, leachate, spent caustic, and resource-recovery projects.
- Study tender documents, scope of work, raw water and effluent characteristics, and treated-water or discharge norms (CPCB, MoEFCC, USEPA, WHO, local regulators), and convert client requirements into an optimized treatment scheme.
- Develop technology selection studies comparing biological (MBBR, MBR, SBR, IFAS, UASB, AnMBR), membrane (UF/NF/RO/EDI), thermal (MEE, MVR, ATFD), and advanced oxidation options on CAPEX, OPEX, footprint, energy, recovery, and sludge generation.
- Prepare Process Basic Engineering Packages for bids: Process Design Basis, block flow and process flow diagrams, mass and energy balance, hydraulic flow diagrams, process descriptions and control philosophy, tentative P&IDs and layout inputs, equipment list with key sizing parameters, and utility consumption summary.
- Carry out equipment and hydraulic sizing across pumps, blowers, clarifiers, DAFs, screens, MBBR/MBR tanks, UASB/EGSB reactors, RO/UF skids, evaporators, crystallisers, ATFDs, sludge handling units, dosing systems, DM/SAC/WAC, EDI, and disinfection systems.
- Generate process calculations: aeration and oxygen demand, sludge generation, RO recovery and flux modelling, evaporation duty, hydraulic gradelines, retention times, and biogas potential.
- Prepare techno-commercial offers with Sales, Mechanical, Civil, Electrical, I&C, and Costing teams; build optioned costing scenarios where required.
- Float vendor RFQs for major equipment packages, technically evaluate offers, and recommend selections to the bid lead.
- Prepare clause-by-clause technical compliance statements, deviation lists, and bid clarifications.
- Drive bid submission timelines and own the technical quality of every proposal that leaves the department.
- Participate in pre-bid, technical clarification, and negotiation meetings with clients, consultants (for example DCPL, EIL, MECON, PDIL, Tata Consulting, Jacobs), and PMC firms, and represent W.O.G. on technical questions.
B. Engineering Documentation and Design Reviews (about 20 percent)
- For awarded projects, support handover to Detailed Engineering: author or review Process Design Basis, PFDs, P&IDs, equipment data sheets, control philosophy, and line lists.
- Participate in and document HAZOP, SIL, HAZID, design reviews, and constructability reviews.
- Approve vendor technical submissions and GADs for process equipment.
- Ensure process deliverables comply with applicable codes and standards: CPHEEO, MoEFCC, CPCB, IS/BIS, ASME, API, ISO 14001, and client-specific specifications.
C. Cross-Functional and Client-Facing Support (about 15 percent)
- Provide technical inputs to Business Development for enquiry qualification, market mapping, and target-account strategy.
- Deliver technical presentations to clients, EPC contractors, government bodies, and consultants.
- Support trade fairs and seminars (for example IFAT India, WaterEx, Aquatech, Chemtech) with technical representation and white papers.
- Provide commissioning and process troubleshooting support to I&C and O&M teams when escalated.
- Conduct plant audits for prospective O&M opportunities and develop revamp or upgrade proposals.
D. Knowledge Management and Innovation (about 5 percent)
- Build and maintain the department's proposal library: reference designs, sizing templates, cost benchmarks, vendor records, and lessons learned.
- Stay current on emerging technologies relevant to W.O.G.: AnMBR, electro-coagulation, electrodialysis, granular sludge, MABR, PFAS destruction, digital twins, and AI-based water quality prediction.
- Contribute to thought leadership through case studies and technical articles.
Qualifications and Experience
Education
- B.E./B.Tech in Chemical, Environmental, Mechanical, or Process Engineering - mandatory.
- M.Tech in Chemical, Environmental, or Water Engineering - preferred.
- Diploma holders considered only with significantly higher experience and a demonstrated proposal-engineering track record.

Seniority note: this specification is pitched at a senior, lead-grade individual contributor. If the approved band and CTC are for a mid-level engineer, retitle to "Process Engineer - Proposals" and reset the experience bar to 6 to 8 years total with 2 to 3 years in proposals, so that title, years, and pay stay aligned.
