Job Description

We are seeking a hands-on NPD & VAVE Mechanical Engineer, with 7-10 years of experience, to develop new products and implement value-engineering, redesign, and lifecycle improvements across fire suppression and nitrogen-generation products. The role combines mechanical system engineering for compressors, pneumatic and pressure circuits, tanks, membranes, filters, regulators, valves, tubing, and manifolds with detailed product design for sheet-metal enclosures, skids, brackets, mounting, vibration isolation, service access, and product integration. The candidate must be able to translate requirements into concepts, calculations, SolidWorks models, production drawings, BOMs, prototypes, verification evidence, and controlled engineering releases. Demonstrated hands-on contribution to both NPD and implemented VAVE or cost-reduction programs is required; this is not a teardown-only, costing-only, orCAD-documentation-only role.

Key Responsibilities

Value Engineering & Cost-Down Execution

Perform product teardown, functional decomposition, BOM/material analysis, benchmarking, and function-cost assessment, translate findings into NPD requirements and redesign opportunities.

Identify opportunities for part-count reduction, common components, alternate materials, simplified interfaces, target-cost achievement, platform reuse, and model-variant rationalization.

Develop VAVE and NPD concepts into complete mechanical designs, calculations, CAD models, prototypes, cost estimates, BOM and drawing updates, and release-ready engineering changes.

Ensure that new and redesigned products improve total value without compromising safety, performance, reliability, serviceability, installation, manufacturability, or compliance.

Pneumatic, Compressor & Pressure-System Engineering

Translate product requirements into pneumatic and mechanical architectures and analyse compressor packages, air and nitrogen flow paths, membrane interfaces, water separators, filters,

regulators, back-pressure regulators, solenoid valves, check valves, relief valves, gauges, pressure switches, drains, and unloaders.

Design and optimize tubing, hoses, NPT or equivalent fittings, manifolds, seals, receiver tanks, storage tanks, and Air Maintenance Device interfaces for new and existing products.

Perform engineering calculations for flow, pressure drop, fill time, compressor duty cycle, leakage, loads, forces, thermal effects, vibration, structural integrity, and safety margins as applicable.

Select and technically qualify compressors, valves, regulators, filters, fittings, tanks, and other mechanical or electromechanical components for NPD, redesign, and VAVE programs.

Mechanical Product Design, Packaging & DFMA

Develop and optimize sheet-metal cabinets, doors, frames, brackets, compressor and tank mounts, vibration isolators, guards, handles, and service-access features for new products.

Create SolidWorks 3D parts and assemblies, layouts, detailed drawings, GD&T, tolerance stacks, material specifications, finish requirements, critical characteristics, and mechanical BOMs.

Apply DFM and DFA from concept stage through release to reduce fabrication steps, welding, machining, fasteners, assembly time, handling, tooling, inspection, rework, and installation effort.

Drive modularity and standardize cabinet, skid, bracket, mounting, fitting, fastener, and tank accessory architectures across representative product platforms.

Own prototype fabrication, fitment checks, assembly trials, design reviews, root-cause analysis, design iterations, corrective actions, and engineering-release updates.

Cross-Functional Collaboration & Implementation

Own mechanical work packages on NPD, redesign, sustenance, and VAVE programs while working closely with the Senior Engineer, Electrical, Firmware, Validation, lab, and US stakeholders.

Define interfaces among compressor and motor packages, control panels, sensors, solenoid valves, controller enclosures, wiring, tanks, tubing, installation hardware, and field connections.

Release requirements, CAD models, drawings, BOMs, specifications, assembly requirements, test criteria, and ECO/ECN documentation through controlled PDM/PLM processes.

Provide technical support to US Supply Chain for supplier reviews, RFQs, component and process qualification, tooling, production trials, new-product launch, and VAVE implementation.

Quantitative Analysis & Business-Case Development

Build target-cost and fact-based cost breakdowns covering material, fabrication, machining, welding, coating, purchased components, tooling, assembly labor, test, packaging, installation, warranty, and lifecycle impact.

Prepare concept and design trade-offs, feasibility assessments .
