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)
