Selective by design.
We are selective by design. Arcseer is built for individuals who have invested seriously in their craft — whether in security research, exploitation, systems engineering, or applied AI. The work demands more than familiarity with tools or frameworks; it requires judgement, discipline, and the ability to reason about complex systems under real-world constraints.
Much of what we do reflects the expectations of organisations operating at scale, where failure has material consequences. We value people who take ownership of problems, who are comfortable with ambiguity, and who hold themselves to a higher standard than is typically required.
"This is not an environment optimised for comfort or speed alone, but for those who want to do work that will endure scrutiny and deliver meaningful impact."
Current openings.
We're looking for a progressive, hands-on People Operations Manager to help build and scale our people function from the ground up. This is a true generalist role for someone who thrives in early-stage environments, enjoys wearing multiple hats, and is passionate about creating a high-performing, people-first culture.
As our People Operations Manager, you will play a pivotal role in shaping the employee experience as we grow. This is not a siloed HR role – you will be a jack-of-all-trades, owning everything from hiring and onboarding to culture, performance, and compliance.
In an early-stage environment, priorities will evolve quickly, so adaptability, pragmatism, and sound judgement are critical. You will partner closely with leadership to design and implement scalable people practices while also rolling up your sleeves to execute day-to-day operations.
Key responsibilities include:
- Building and refining hiring processes to attract high-quality talent
- Designing onboarding experiences that set employees up for success
- Supporting managers with performance management and development frameworks
- Establishing core people policies and ensuring compliance with relevant regulations
- Driving employee engagement, culture, and internal communication initiatives
- Managing HR operations including contracts, benefits, and employee records
- Acting as a trusted advisor to leadership on people-related decisions
You will thrive in this role if you:
- Enjoy working across a broad range of people topics rather than specialising in one area
- Are comfortable operating with ambiguity and limited structure
- Take ownership and execute with a bias for action
- Balance empathy with commercial awareness
- Are motivated by building something from scratch and seeing it scale
This is an opportunity to define the people function in a growing company and have a meaningful impact on how we hire, develop, and support our team.

You will be responsible for building rapport with customers, understanding their challenges, and helping communicate how Arcseer can support them. You will also play a key role in feeding customer insights back into the business, helping shape product development and positioning.
Key responsibilities include:
- Engaging with prospective customers via outreach, events, and inbound enquiries
- Building strong, trust-based relationships with customers
- Understanding customer needs and articulating Arcseer's value proposition
- Supporting senior sales team members in progressing opportunities
- Maintaining accurate and up-to-date records in CRM systems (e.g. HubSpot)
