Office Assistant

About Modo Energy

The energy transition is the biggest infrastructure buildout in human history. Modo Energy is the data platform at the centre of it.

We build the benchmarking, forecasting, and valuation tools that the world's most serious energy investors, developers, and operators depend on to make decisions. If a battery gets financed, built, or traded anywhere in the world, there's a good chance Modo data was in the room.

Founded in 2019, we're 75+ people across London, New York, Sydney, and Madrid; $30M Series B, AI-native, and moving fast.

This is a rare chance to join a category-defining company at the moment it's scaling globally.

The Role

This is a part-time, in-person Office Assistant role based in our Euston office in London. You'll be in the office Tuesday, Wednesday, and Thursday, ~8:30am–6:30pm, with additional availability expected for events, team offsites, and the occasional weekend ask.

This is not a quiet role. No two days are the same. You'll be handed things with minimal context and expected to figure them out. You'll get direct, honest feedback — often — and you'll need to both welcome it and act on it immediately.

The ceiling here is genuinely high. Do the job well and it becomes whatever you're capable of making it — full-time EA, events lead, Chief of Staff. But you have to earn it.

What You'll Do

• Own the day-to-day running of the London office — cleanliness, facilities, Wi-Fi, vendor relationships, and anything that keeps the space functioning


• Manage the cleaning team and all facilities contractors


• Keep the office stocked with snacks, drinks, and supplies


• Plan and coordinate team social events


• Maintain and update office information for new hires and the broader team


• Coordinate on-site interviews — logistics, hospitality, scheduling


• Manage guest visits from arrival to departure


• Support team offsites and leadership events


• Pick up whatever else needs doing — and there will always be something

What We're Looking For

The Essentials

• Some experience in an administrative, operations, or office management role — you've done something like this before and you were good at it


• Direct, concise communication style — you say what you mean and you mean what you say


• High ownership mentality — you don't wait to be told twice, and you don't let things fall through the cracks


• Composure under pressure — fast-paced environments don't rattle you, they energise you


• Strong organisational instincts — you track details, follow through, and close loops without being chased


• Comfortable picking up new technology quickly — you actively seek out tools, including AI, that make you faster and better at your job

Nice To Have

• Experience at a startup or high-growth company


• Familiarity with tools like Slack, Notion, Google Workspace


• Interest in growing into a broader operations or EA function

Equal Opportunity & Legal

Modo Energy is an equal opportunity employer. We welcome applicants of all backgrounds and do not discriminate on the basis of race, gender, age, disability, national origin, or any other protected characteristic. This is an in-person role based in London. You must have the right to work in the UK — we are not able to offer visa sponsorship.

What You Can Expect From Us

• Competitive hourly pay


• A direct line to senior leadership and real operational responsibility from day one


• Genuine room to grow — in scope, hours, and seniority — based on your performance


• A high-quality team that takes the work seriously and each other seriously


• An environment where good work is noticed and rewarded, and where your career can go in directions you haven't thought of yet

What You Can Expect From Us

At Modo Energy, we believe that exceptional work deserves exceptional reward. We're a high-performance team; ambitious, collaborative, and genuinely motivated by the scale of what we're trying to build.

You'll have real ownership from day one, work alongside some of the brightest people in the industry, and be part of a company that's defining a new category in the global energy market. We're hybrid: everyone works Tuesday to Thursday in office, with Monday and Friday flexible. We offer top-of-market compensation, equity for every employee, and the space to take your career wherever you want it to go.

We're looking for people who want to do the best work of their careers. If that's you, we want to talk.
