What You'll Do

Executive support

• Own making the leadership's travel and calendar manageable: sharp calendar judgement, end-to-end travel coordination (itineraries, accommodation, contingency plans), and the instinct to protect their time without being asked.
• Support inbox management, correspondence, and follow-ups, and act as a reliable point of contact between leadership and internal or external partners.
• Handle expense reporting and reconciliation accurately and on time.
• Prepare and coordinate materials for leadership, board, or all-hands meetings: agendas, pre-reads, minutes, and follow-up on action items.
• Track action items, deadlines, and workflows across ongoing projects, so nothing falls through when priorities shift.
• Spot friction before it becomes a problem, and fix the process behind it, not just the one instance.
• Handle confidential and sensitive information with discretion, as standard.

Workplace experience and culture

• Serve as the primary point of contact for our Camden office: employees and guests, with a warm and professional welcome.
• Make our Camden office a place people want to come into: weekly catering, a stocked snacks section, and the everyday moments that build a team.
• Run our offsites. Keep the leadership team's workshops and room bookings sorted so their time together isn't wasted on logistics.
• Support internal communications and culture initiatives, and look for opportunities to improve the day-to-day experience of the office.

Office operations and administration

• Own the day-to-day running of the office: supplies, equipment, and the space itself, so it's always functional, tidy, and well stocked.
• Maintain basic office administration: mail, deliveries, and correspondence.
• Own new team member onboarding and offboarding end-to-end. A new starter's first week should feel looked after, and someone leaving should have the smoothest farewell.
• Build and maintain our SOPs in Notion, so how CarbonChain actually works lives somewhere real, not in one person's head.

What We're Looking For

• 5+ years of experience in an EA, office management, workplace experience, or operations role.
• Strong judgement: you can tell what's urgent, what can wait, and what needs to be escalated, without needing to be told, and you're comfortable with ambiguity rather than waiting for step-by-step direction.
• You already use AI tools, e.g. Claude or scheduling agents, as part of how you work. You are comfortable using AI day to day to move faster on the transactional tasks, so you can spend your own time on what actually needs a human - judgement, prioritisation, and reading the room.
• Excellent written and verbal communication, comfortable with executives, colleagues, and external partners alike.
• Discretion and maturity with confidential information.
• A proactive mindset: you spot what's needed before it's asked for, and you deal with the cause rather than just the symptom.
• Care about culture and the small details that make an office a good place to work

Nice to have

• Experience in a high-growth start-up, scale-up, or another fast-paced professional environment.
• Exposure to budgeting, vendor negotiation, or basic bookkeeping.
• Experience supporting a founder or C-level executive directly.
