Research Associate, Analytical

About The CompanyAether Biomachines is a deep tech company building at the intersection of biology, machine learning and materials science. Our platform combines high-throughput biological screening with advanced materials development to get novel materials from lab discovery to real-world production faster than traditional R&D allows. We're starting starting in additive manufacturing and expanding into high-performance polymers. We operate out of Menlo Park and South San Francisco.About The TeamThe Materials team sits at the center of that bridge: translating what the biology platform discovers into materials that actually ship. It's a small, hands-on group, which means you'll be doing bench work and first-principles thinking in the same week. Everyone is close to the science.About The RoleWe’re looking for an Analytical Research Associate to support our materials and product development efforts through hands-on analytical testing, with a primary focus on gel permeation chromatography (GPC). This is an early career, lab-intensive role ideal for someone who enjoys running samples, maintaining instruments, and ensuring high-quality, reproducible data in a fast-moving research environment.In this role, you’ll spend the majority of your time preparing and running polymer samples on our GPC systems, working closely with an analytical scientist and collaborating with scientists across the materials team. You’ll also play an important role in instrument maintenance, calibration, troubleshooting, and documentation - helping ensure our analytical methods perform consistently and reliably.While this role is primarily execution-focused, it offers room to grow over time into deeper analytical ownership, including method development and expanded responsibility across chromatography-based techniques. This role is onsite at our South San Francisco facility.About YouYou’re someone who enjoys being in the lab, takes pride in producing reliable data, and thrives in a small, highly technical startup environment. You balance attention to detail with flexibility and creativity, communicate clearly with teammates, and aren’t afraid to flag issues early when something doesn’t look right.What You’ll DoPrepare and run polymer samples on GPC systems, following established methods and SOPsTrack method performance to ensure data quality, reproducibility, and consistency over timePerform routine instrument maintenance, calibration, and troubleshooting, escalating issues as neededIdentify clearly problematic or compromised data and communicate issues proactivelyCollaborate closely with an analytical scientist on scheduling, priorities, and technical problem-solvingSupport materials scientists and engineers by running analytical tests for ongoing experimentsMaintain accurate records of experiments, maintenance, and calibrationsContribute to writing or updating SOPs and best practices as the lab and team evolveOver time, take on additional ownership such as consumables management, method improvements, or expanded analytical scopeWhat We’re Looking ForRequired / Core SkillsHands-on experience running samples on a SEC/GPC or similar LC system (academic or industry)Strong fundamentals in chromatography and laboratory best practicesExperience working with polymers (synthetic and/or biopolymers)High attention to detail and commitment to data qualityComfort working independently while collaborating closely with othersAbility to recognize when data or samples are clearly problematic and speak upSafe lab practices, including handling chemicals, solvents, and glasswareNice to HaveIndustry experience (1-3 years preferred, but not required)Exposure to instrument calibration, maintenance, or troubleshootingExperience with multiple analytical techniques beyond GPCFamiliarity with rheology or interest in learning additional techniquesExperience contributing to SOPs or method documentationGrowth & DevelopmentThis role is designed to grow with the right person. As our analytical needs expand, strong performers may take on:Greater ownership of GPC methods and performance trackingInvolvement in method development and optimizationBroader analytical responsibilities across chromatography-based techniquesA longer-term path toward expanded scientific or technical roles, aligned with individual interestsNoteAether Biomachines is proud to be an Equal Opportunity Employer.
