Office Manager / Generalist & Executive Assistant

HydroNeo is an international smart aquaculture technology company based in Bangkok and the market leader in Thailand, with an expanding footprint across Southeast Asia, including a growing subsidiary in Indonesia.

We are a young, fast growing company, and our Bangkok office is where our standards are set for the rest of the group. That means the bar here is high. Process discipline, confidentiality, and reliable execution are not optional extras, they are the foundation everything else is built on.

We are hiring an Office Manager & Generalist to run our Bangkok office day to day, own our administration with Thai authorities, banks, and external partners, and keep the operational engine of the company running properly. As part of this role, you will also act as the direct assistant to the CEO, the one person he can rely on without exception, including when he is traveling or in another country.

What we need most is stability of character. This is a rock in the surf role: someone calm and steady under pressure, a fixed point the office can orient around no matter what is happening around them. No drama, no gossip, no politics, and absolute discretion with confidential and sensitive matters. In exchange, you get real professional authority in your area and the CEO's full trust.

If you are at your best when you can take a messy situation and turn it into something organized, on time, and properly documented, this is a senior, high trust, long term role with broad exposure and real career stability. This role goes beyond standard office hours: as part of supporting the CEO directly, you will occasionally handle a message, a call, or a quick coordination matter outside working hours, not as routine overtime, but as part of being a trusted right hand. In return, you will have genuine flexibility when you need it as well.

Office Manager & Generalist

• Run the Bangkok office day to day: supplier coordination, logistics, mail, document flow, office supplies, visitor handling, and general upkeep.
• Take personal, hands-on responsibility for the office itself: a clean, tidy, well presented space at all times, small issues fixed or flagged before they become problems, plants and common areas looked after, and the office always ready to receive a visitor or client on short notice.
• Handle all interactions with Thai authorities, banks, and external service providers: company bank accounts, BOI compliance and reporting, work permit and visa processes for foreign staff, Social Security Office registrations and reporting, and Department of Business Development filings.
• Manage all company paperwork and administration: contracts, filings, licenses, employment documents, and a clean, well organized digital filing system on SharePoint.
• Uphold and strengthen the operational structure of the Bangkok office: internal processes, filing systems, expense and invoice workflows, onboarding routines, office policies. Where a process is unclear or starting to slip, your job is to fix it and make it hold, not let it drift.
• Support local HR matters: onboarding new hires, day to day employee questions, and making sure company rules and standards are understood and followed, including knowing what needs to be escalated to the CEO rather than handled quietly on your own. Listen when needed, but also enforce the line.

Executive Assistant to the CEO (second part of the role)

• Act as the direct assistant to the CEO: expense reports, diligent follow ups on open items, ad hoc special projects, meeting preparation and minutes, correspondence, and translations during meetings, including coordination with our Indonesian office when needed.
• Hold the fort confidently when the CEO is traveling, with clear judgment about what can be decided locally and what must be escalated immediately, and absolute discretion with confidential, legal, and HR matters.

• 5+ years in office management, general administration, or senior executive assistance, including direct support of a senior executive or founder.
• Solid working knowledge of Thai business practice: how to deal with banks, the Revenue Department, BOI, the Social Security Office, immigration, and the Department of Business Development. You understand the reporting cycles, you know what documents are needed and when, and you know how to push a process to completion without it sitting in someone's inbox for three weeks. Experience with a BOI promoted company is strongly preferred.
• Absolute discretion with confidential, legal, and financial information. You do not discuss company matters outside a strict need to know circle, and you know what must be escalated to the CEO immediately rather than held back or handled quietly.
• Comfortable working in a young, fast growing company environment. You can take ownership of a messy area, design a sensible structure, and put it in place without being told how, and you know when to ask before deciding.
• A demonstrated track record of reliability. Colleagues and partners can set their watch by your follow through, and issues raised with you do not need to be raised twice.
• Comfortable with the natural flexibility of a senior support role. You understand that occasional contact outside office hours is part of working closely with a founder, and you handle it with maturity rather than counting hours. We respect your time and your boundaries, and we expect the same professional judgment in return.
• Fluent Thai and strong professional English (written and spoken). You will translate between the CEO and Thai partners, employees, and authorities regularly.
• Genuinely advanced Microsoft 365 skills: Excel (pivot tables, XLOOKUP/VLOOKUP, structured tables, formulas, not just data entry), Outlook, Word, Teams, and SharePoint. Comfortable building and maintaining a digital filing system used by the whole team.
• Confident communicator who can be polite and firm in the same sentence, and comfortable holding suppliers, partners, and colleagues to deadlines.
• A track record of running things independently. You do not wait to be told twice, and you do not drop balls.

• Experience in a startup, tech company, or international SME.
• Experience working directly with foreign founders or international executives.
• Experience supporting a BOI promoted company.
• Familiarity with HubSpot, Xero, or similar business systems.

Personality fit
We are looking for someone who brings genuine seniority to how they work: organized to a high standard, calm under pressure, and confident enough to push back, follow up, and keep things on track without drama. Picture the rock in the surf, steady and dependable no matter what is churning around it. You do not gossip, you do not get pulled into office politics, and colleagues always know exactly where they stand with you. Your loyalty to the CEO and to the company is absolute, and so is your professionalism when things get busy or stressful.

You take pride in a tidy office, a clean inbox, a well prepared meeting, and paperwork that is always ready before it is needed. You are comfortable saying "let me set up a proper process for this" rather than letting things continue chaotically.
