Office Manager

Lydian is developing the lowest cost sustainable fuels from waste CO2, water, and renewable electricity to decarbonize the aviation industry. Our breakthrough technology replaces oil and gas refining with fully electrified, modular, and flexible reactor systems that produce fuel with 95% lower emissions than traditional jet fuel.

Since our founding in 2021, Lydian has achieved key milestones in record time, including the production of our first liquid fuel from our pilot system, capable of producing ~10,000 gallons of fuel per year for a fraction of the capital and time of alternative approaches. Lydian is backed by top climate investors including Congruent Ventures, Galvanize Climate Solutions, Union Square Ventures, Voyager Ventures, Grok Ventures, and Overture. We are building a motivated, diverse, and collaborative team that is passionate about addressing the growing climate crisis and is committed to excellence in their work. In particular, we look for tenacious people who are energized by solving the hardest, highest impact problems that come their way.

We are hiring a highly organized and proactive Office Manager to serve as the operational backbone of our Boston headquarters. This role is central to keeping our team moving, ensuring our financial workflows are seamless, and maintaining a world-class physical workspace. You will own the gears of the office - from managing accounts payable and procurement to orchestrating team culture and facility logistics. We are looking for someone who takes pride in "setting the stage" so that the technical team can work without operational friction, and is as comfortable auditing a spreadsheet as they are assembling a whiteboard or moving packages.

This role is fully onsite. Because you are the primary point of contact for physical operations, mail, and facility improvements, a consistent onsite presence is required.

• Manage vendor setup (NDAs, tax forms), collect competitive quotes, and maintain all digital records in Notion and SharePoint

• Direct all incoming/outgoing mail and equipment returns

• Audit and restock office, kitchen, and snack inventories

• Serve as the primary POC for Hood Park management and operational vendors (cleaning, security, and utilities)

• Lead physical office improvements, including space measurements, furniture assembly, and layout optimizations

• Orchestrate internal company events, team-bonding activities, and happy hours

• Provide Administrative Assistant support to our CTO

• Execute the "Day 1" experience for new hires, including desk setups, hardware deployment, and building access

• 4+ years in office management or operations, ideally in a startup or industrial environment

• Proficient in tools like Ramp, Notion, SharePoint, and DocuSign

• Familiar with Boston-based vendors and shipping/courier logistics

• Able to identify operational bottlenecks and solve them autonomously

• Able to handle sensitive financial data and executive signatures with total discretion

• Alignment with our mission, vision, and virtues

• Challenging, collaborative, and meaningful work and an important voice in company development

• Competitive salary commensurate with experience

• Meaningful equity compensation

• Flexible PTO and expectation that all employees take significant time off to rest, recharge, and enjoy life outside work

• Excellent health insurance with 100% of healthcare, vision, and dental premiums covered

• 401(k) with company match
