Senior Engineer II, Mechanical/Dispersion Systems at Flagshippioneeringinc

COMPANY DESCRIPTION Flagship Pioneering is a bioplatform innovation company that invents and builds companies that change the world. We bring together the greatest scientific minds with entrepreneurial company builders and assemble the capital to allow them to take courageous leaps. Those big leaps in human health, sustainability and beyond exponentially accelerate scientific progress in areas ranging from disease detection and treatment and nature-positive agriculture to novel applications of AI that are driving the creation of new technologies. What sets Flagship apart is our ability to advance science and technology by uniting innovation, company creation, and capital investment under one roof in a way that is largely without precedent. Our scientific founders, entrepreneurial leaders, and professional capital managers are each aligned around an institutionalized process that enables us to innovate and transform for the benefit of people and planet. Many of the companies Flagship has founded have addressed humanity’s most urgent challenges: vaccinating billions of people against COVID-19, curing intractable diseases, improving human health, preempting illness, and feeding the world by improving the resiliency and sustainability of agriculture. Flagship has been recognized twice on FORTUNE’s “Change the World” list, an annual ranking of companies that have made a positive social and environmental impact through activities that are part of their core business strategies, and has been twice named to Fast Company’s annual list of the World’s Most Innovative Companies. THE ROLE We are seeking a highly motivated, proactive, and detail-oriented Sr. Engineer II, Mechanical/Dispersion Systems to lead the design and development of aerosol dispersal systems. This role will be responsible for owning the mechanical design and performance of systems that control the release and distribution of particulate materials in real-world trials. The ideal candidate combines strong fundamentals in fluid/particle dynamics with hands-on experience building and iterating physical systems. The individual will work cross-functionally with scientists, engineers, and external partners to translate novel materials into robust hardware. Success in this role requires comfort operating in a fast-paced, experimental environment and the ability to independently drive complex engineering efforts from concept through deployment. KEY RESPONSIBILITIES • Lead the design and development of dispersion systems, owning mechanical performance from concept through prototyping and validation. • Design and optimize particle and fluid handling systems, including mechanisms for controlled release, flow regulation, and dispersal behavior. • Develop hardware intended for integration with mobile and diverse platforms, accounting for size, weight, power, and environmental constraints. • Rapidly prototype and iterate on designs using hands-on build methods (e.g. 3D printing, machining) with a strong emphasis on learning and designing through experimentation. • Design and execute bench-scale tests to evaluate system performance, including flow rates, particle distribution, and repeatability. • Work with external manufacturers and machine shops to fabricate components, refine designs for manufacturability, and scale builds. PROFESSIONAL EXPERIENCE & QUALIFICATIONS • Bachelor’s degree in mechanical, aerospace or related engineering discipline with 8+ years of relevant industry experience, or Master’s degree with 6+ years of experience, or PhD with 3+ years of experience. • Strong foundation in fluid dynamics and particle behavior with experience designing systems involving spray or particulate dispersion. • Demonstrated ability to own end-to-end mechanical design from concept -> prototype -> testing -> iteration. • Proficiency in 3D CAD tools (SolidWorks, Fusion, OnShape). • Must be available for onsite employment in North Denver/Boulder Metro, Colorado. • Initiative and ability to manage multiple, competing priorities, to think strategically and execute methodically. • Strong organizational and project management skills, with the ability to independently drive initiatives in a fast-paced environment. • Excellent communication and documentation skills, with the ability to clearly articulate design decisions and tradeoffs.
