Top Tech Jobs & Startup Jobs

Develop and scale the process chemistry for continuous production of ion-exchange media. Responsibilities include reactive bath formulation, conversion, washing, drying, QC methods, process operating windows, bench and pilot trials, mass balances, reagent recovery, waste treatment, SOPs, and hazard reviews. The engineer will translate laboratory recipes to a demonstration roll-to-roll line and collaborate with chemical process engineering on equipment and production scale-up.

Design and integrate an automated roll-to-roll production line for ion-exchange media, including web transport, unwind/rewind systems, tension control, drives, PLCs, HMI/SCADA, recipes, data logging, safety systems, and commissioning. The role leads line-level controls integration and troubleshooting across sensors, actuators, electrical components, drying, baths, and connected unit operations, with frequent extended hours during critical project milestones.

Summer engineering intern assigned to electrical and instrumentation, controls, mechanical, or chemical process engineering. Responsibilities include owning an engineering deliverable, producing technical documents and calculations, supporting pilot commissioning, calibrating instruments, analyzing pilot data, and coordinating with vendors on specifications and quotes. The role is based in Chattanooga for approximately 12 weeks during summer 2027 and may lead to a full-time opportunity.

Summer commercial intern supporting critical-mineral project development. Responsibilities include sourcing candidate resources, contacting mines and industrial partners, arranging samples, maintaining resource databases, modeling project and process costs, analyzing assay and mass-balance data, and preparing partner briefing materials. The role works directly with the CEO and engineering team in Chattanooga, includes occasional domestic travel, and may lead to full-time employment.

Leads finance for a venture-backed industrial technology company, overseeing close, GAAP accounting, cash and runway, government contract accounting, FP&A, tax, controls, board reporting, fundraising, deal structuring, project finance, and finance team development. The role is intended to progress to CFO, with responsibility for joint ventures, royalties, offtake agreements, debt financing, and Series A capital strategy.

Chief of Staff supporting the CEO across partnerships, negotiations, contract structuring, hiring, and administrative coordination. Responsibilities include preparing deal materials, researching counterparties, tracking contract redlines, managing executive and team searches, triaging inbound requests, coordinating schedules, and tracking commitments across multiple ventures. The role requires frequent travel, extended hours, discretion, exceptional writing, modeling skills, and comfort operating in a fast-paced early-stage environment.

Owns mechanical engineering for a modular chlorination and metal recovery plant. Responsibilities include specifying process equipment, piping, valves, materials of construction, and skid layouts; evaluating vendors; supporting factory acceptance testing; and overseeing installation, testing, pre-commissioning, and mechanical completion. The role requires corrosive-service equipment expertise, coordination with process engineers and contractors, site travel, and leadership across multiple future capital projects.

Own the electrical and instrumentation scope for a chlorination and metal-recovery plant. Develop the electrical basis of design, load list, single-line diagrams, hazardous-area classification, instrument index, I/O list, and safety instrumented system requirements. Specify and review MCCs, drives, panels, instruments, cabling, and contractor designs. Support HAZOP, factory acceptance, energization, loop checks, interlock testing, commissioning, and future capital projects, with potential leadership across multiple projects.

Leads a DARPA-funded nanocrystal catalyst research program, including experimental design, sample preparation, testing, metrology, data analysis, milestone reporting, and mentoring an Engineer II. Also develops metal recovery processes from bench and pilot testing through mass and energy balances, process design bases, P&IDs, and equipment specifications. Oversees laboratory safety, SOPs, cross-functional coordination, and government sponsor presentations.

Lead process engineering for hydrometallurgical metal recovery projects from flowsheet development through plant commissioning. Develop mass, energy, and water balances; create techno-economic models; author PFDs, P&IDs, equipment specifications, and operating procedures; size unit operations; run pilot campaigns; support scale-up, FEED, detailed engineering, commissioning, and startup. The role requires close collaboration with metallurgy teams and EPCM partners in a high-autonomy startup environment.
