Sr. Manager, Events - Houston

Position Overview

Greentown Labs is seeking a strategic, hands‑on Sr. Manager, Events to own the strategy and execution of our Houston event portfolio. Reporting to the Director of Strategic Programs and Events, this role leads the planning and delivery of all Houston‑based programming — including the annual Climate Tech Summit, member‑facing events, pitch days, ecosystem conferences, third‑party rentals, tours and executive engagements.

You’ll bring a portfolio‑level lens to our Houston events: setting strategy and KPIs, owning budgets and vendor relationships, and partnering across Houston and Boston to make sure our Houston presence reflects the ambition of Greentown’s mission. You’ll also own our Houston site‑level social media (Instagram) and serve as our on‑the‑ground content lead, surfacing the moments worth amplifying across our member community.

This is a role for an operator who has run large‑scale events end‑to‑end, who can move between strategic planning and on‑the‑ground execution without missing a beat, and who is energized by working in a fast‑paced, mission‑driven environment.

• Own the Houston event strategy, calendar, and KPIs — from member mixers and pitch days to large‑scale climate tech summits and executive engagements
• Lead end‑to‑end planning and execution of the annual Climate tech Summit, including speaker outreach, sponsorship logistics, volunteer coordination, and on‑site operations
• Own budget development and tracking across the Houston event portfolio; negotiate vendor contracts and identify opportunities to drive cost efficiency without compromising on quality
• Develop post‑event reporting and continuous‑improvement loops — what worked, what didn’t, and what to standardize across the portfolio

• Serve as the senior operational lead for all Houston events and tours — public programming, member‑hosted events, and third‑party rentals — owning the full lifecycle from intake to wrap‑up
• Direct venue, vendor, catering, AV, and run‑of‑show coordination using Greentown’s Asana event templates; level up the templates where the system can carry more weight
• Manage event registration, check‑in, and data integrity on Greentown’s Luma platform
• Evaluate inbound third‑party event requests and ensure every hosted event is mission‑aligned with Greentown’s climate tech focus
• Track event KPIs — attendance and registration rate, attendee satisfaction, social impressions and engagement, budget adherence, on‑time program execution — and report quarterly to leadership

• Own Greentown Labs Houston’s site‑level Instagram: strategy, content calendar, posting cadence, voice, and community engagement
• Lead pre‑event buzz, live coverage, and post‑event content; produce photo and video on the ground at events and contribute to HQ Linked In coverage
• Surface moments worth amplifying across our member community — bring an editorial eye to the day‑to‑day
• Partner with the Marketing & Communications team in Boston to align voice, brand, and cross‑channel storytelling

• Direct Greentown’s participation and presence in external conferences and ecosystem events — booth coordination, registration, team briefings, and executive prep
• Manage end‑to‑end speaker and panelist support for events Greentown hosts or participates in: logistics, materials, A/V requirements, run‑of‑show, and on‑site green room operations
• Coordinate executive speaking engagement preparation and follow‑up across the Houston leadership team
• Partner with Boston‑based events and marketing colleagues to build a coherent Greentown event experience across both sites
• Develop the Houston event ops playbook — repeatable processes, templates and standards that scale with our team
• Mentor and direct future hires or contractors as the Houston events team grows

You are a seasoned events operator who can hold strategy and execution at the same time. You are mission‑driven, calm under pressure, and energized by being in the room. You are:
