Job description

PhysicsX is a deep-tech company of scientists and engineers, developing machine learning applications to massively accelerate physics simulations and enable a new frontier of optimisation opportunities in design, engineering, and systems control.

We help our customers fundamentally improve their concepts and designs, transform their engineering processes and drive operational product performance. We do this in some of the most advanced and important industries of our time – including Renewables & Sustainability, Space, Aerospace, Medical Devices, Additive Manufacturing and Energy. Our work creates positive impact for society, be it by improving the design of artificial hearts, reducing CO2 emissions from aircraft and road vehicles, or increasing the performance of wind turbines.

Position Overview:

As People Operations Assistant, you'll be a vital part of our People team, managing administrative and operational HR tasks. You’ll gain exposure across the employee lifecycle and play an active role in supporting our global team — including coordination of onboarding, employee records, systems, compliance, and visa processes.

We know that innovation doesn’t just happen in code - it happens in how we build our teams, culture, and operations. As we scale, we’re looking for someone who is organised, proactive and excited to help us shape the foundations of a international deep-tech company.

What you'll do

• Maintain and update employee data in our HR systems and internal tools (e.g., HRIS, Notion etc)
• Assist the coordination of onboarding and off-boarding processes globally, ensuring smooth documentation, systems setup, and transitions
• Support the creation and tracking of HR documents — employment verifications, probation letters, and more
• Deal with employee queries about policies, systems, time-off, or HR documentation
• Assist with benefits administration, including tracking enrolment, supporting claims, and liaising with vendors
• Manage internal visa processes — supporting new hires with visa applications, renewals, or relocation documentation, this includes coordinating visa-related support for project-based travel or cross-border assignments, working with external immigration providers as needed
• Maintain and organise HR documentation to ensure legal and audit compliance
• Assist with preparation of regular HR reports and dashboards, ensuring clean and accurate data
• Take part in scaling and optimising People Ops processes as the company grows.

What the ideal candidate looks like

• 1-2 years prior administrative experience in HR, People Ops, or visa/mobility support
• A strong interest in HR and operations, with a willingness to learn and grow
• Excellent organisation and attention to detail
• Strong communication and interpersonal skills
• Ability to manage confidential information with discretion
• Tech-savvy and eager to learn systems like HRIS platforms, Notion, Slack, etc.
• Self-motivated and adaptable in a fast-paced, globally distributed environment

What we offer

• Be part of something larger: Make an impact and meaningfully shape an early-stage company. Work on some of the most exciting and important topics there are. Do something you can be proud of
• Work with a fun group of colleagues that support you, challenge you and help you grow. We come from many different backgrounds, but what we have in common is the desire to operate at the very top of our fields and solve truly challenging problems in science and engineering. If you are similarly capable, caring and driven, you'll find yourself at home here
• Experience a truly flat hierarchy. Voicing your ideas is not only welcome but encouraged, especially when they challenge the status quo
• Work sustainably, striking the right balance between work and personal life.
• Receive a competitive compensation and equity package, in addition to plenty of perks such as generous vacation and parental leave, complimentary office food, as well as fun outings and events

We value diversity and are committed to equal employment opportunity regardless of sex, race, religion, ethnicity, nationality, disability, age, sexual orientation or gender identity. We strongly encourage individuals from groups traditionally underrepresented in tech to apply. To help make a change, we sponsor bright women from disadvantaged backgrounds through their university degrees in science and mathematics.
