Senior Client Solutions Architect Location: Houston, TX area strongly preferred; remote candidates in North American time zones will be considered About OLI: OLI is the global standard for electrolyte chemistry simulation, with over 50 years of peer-reviewed science embedded in its platform. More than 500 enterprises and academic institutions across 35+ countries rely on OLI software to make confident, defensible engineering decisions—predicting scale formation, modeling corrosion, simulating extraction and refining processes, and optimizing water chemistry from reservoir to wellhead to facility. Our customers include energy majors, lithium producers, NASA, and leading water treatment operators. We are building the digital infrastructure that makes complex chemistry computable, accessible, and actionable in real time. Your Role: We are hiring a Chemical Engineer with hands-on upstream oil and gas experience who combines field-tested instincts with technical rigor and strong communication skills to design chemistry-driven solutions for complex industrial systems. As a Client Solutions Architect, you will apply predictive thermodynamics using OLI Studio and OLI Flowsheet to solve real-world water and electrolyte challenges in upstream O&G environments — from produced water management and scale inhibition to wellbore chemistry and flow assurance. You will work directly with customers and partner with Sales, Product, and Client Success to translate technical insight into measurable operational and commercial value. This is a market-facing technical leadership role that directly supports growth through credible, defensible solutions built on real field understanding. We’re Looking For: Chemical Engineer Committed to Excellence You hold a degree in Chemical Engineering and take pride in doing technically rigorous, defensible work. You care about getting the chemistry right — especially under the messy, variable conditions of real production systems. Endlessly Curious and Technically Disciplined You question assumptions, validate results, and pursue root causes. You are driven to understand how and why systems behave the way they do — in the lab and in the field. Driven to Apply Chemistry Differently You are energized by using predictive modeling and simulation to solve problems others approach with guesswork. You look for more rigorous, scalable approaches to upstream chemistry challenges. Structured Problem Solver with Long-Term Ownership Mindset You convert complex customer challenges into disciplined, repeatable modeling workflows. You think beyond one-off answers and build solutions that hold up across wells, fields, and operators. Customer-Obsessed, Collaborative Communicator You explain complex chemistry clearly to both engineers and operations personnel. You work effectively across customers, sales, research, and engineering teams, and you care deeply about delivering measurable impact in the field. If these five traits are not present, this role will not be a fit. Key Responsibilities: Design and Deliver Chemistry-Driven Solutions - Use OLI Studio and OLI Flowsheet to analyze produced water, brine, and electrolyte systems in upstream O&G contexts. - Build technically sound, defensible modeling workflows aligned with real production challenges — scaling, corrosion, flow assurance, and water handling. - Interpret plant and field chemistry data and reconcile operational observations with predictive results. - Clearly articulate modeling assumptions, constraints, and implications to technical and non-technical audiences. Support Commercial Engagements - Partner with Sales on technical discovery, qualification, and solution design for upstream O&G accounts. - Lead technical components of evaluations, pilots, and proof-of-concept engagements. - Deliver tailored demonstrations tied to operational outcomes: scale risk reduction, corrosion mitigation, treatment optimization, and cost control. - Contribute to proposals and technical value narratives. Build Vertical Expertise - Develop depth in upstream O&G chemistry — produced water, scale management, wellbore chemistry, and corrosion engineering. - Identify recurring chemistry pain points across the upstream segment and translate them into repeatable OLI-based solution frameworks. - Represent OLI in technical discussions with operators, service companies, and engineering consultants. - Influence Product and Solutions - Capture structured voice-of-customer insights from field and customer engagements. - Identify high-value modeling and chemistry gaps relevant to upstream operations. - Contribute to standardized solution templates and vertical offerings. Experience Required: - B.S. in Chemical Engineering, Chemistry, or related field - 7+ years of experience in upstream oil and gas, with direct exposure to produced water management, flow assurance, scale inhibition, or water injection systems - Experience using OLI Studio and/or OLI Flowsheet (or demonstrated ability and strong motivation to develop proficiency quickly) - Experience presenting technical content to engineering and operations audiences - Working knowledge of: - Aqueous and produced water chemistry - Scaling, precipitation, and mineral deposition - Acid–base and carbonate systems - Corrosion mechanisms in electrolyte and H₂S/CO₂ environments (preferred) We’re Offering: - A chance to be part of a visionary company that is solving complex global challenges. - A collaborative and dynamic work environment where innovation is at the heart of what we do. - Competitive compensation package, including incentives and bonuses based on performance. - Opportunities for personal and professional growth. Why This Role: This is a rare opportunity to sit at the intersection of rigorous chemistry modeling and real upstream operations — working with customers who face concrete, high-stakes problems every day and building solutions that translate directly into field results.
