What it’s like to work at Topsort

At Topsort, we communicate openly and move fast. We say things as they are, challenge each other early, and embrace feedback with curiosity—it’s how we build better, faster. Every experiment has a purpose, and every outcome helps us make the next decision smarter. There’s no single formula for success here; we find what works, improve it, and scale it.

We’re collaborative internally and competitive externally—never the other way around. The pace is quick, sometimes a 100-mph kind of fast, and that’s what keeps it exciting. We act with intent, lift each other up, and turn bold ideas into real results. No endless meetings here—if it can be done today, it gets done today.

What is this role like

We’re hiring an HR Generalist based in our São Paulo office to support our growing team in Brazil and work closely with our global People function. This is a hands-on role for someone who enjoys being close to the business—supporting hiring, people operations, and office life while helping a fast-growing tech company scale with intention.

What you will do

• Support recruiting efforts, including sourcing coordination, interviews, and offer processes.
• Own employee onboarding and create a strong, welcoming first experience for new hires and visitors.
• Manage core HR operations in Brazil, including contracts, compliance, labor law requirements, and policies.
• Partner with the People team on employee programs, tools, and process rollouts.
• Plan and support internal events, trainings, and workshops.
• Help keep the office running smoothly by supporting day-to-day office operations and coordination.
• Act as a trusted point of contact for employees, ensuring a positive and well-organized people experience.

What we’re looking for

• Degree from a strong academic institution
• 4+ years of experience in HR, People Operations, or a similar role.
• Experience in a tech or high-growth environment is a plus.
• Comfortable working across recruiting, operations, and employee experience.
• Organized, proactive, and able to juggle multiple priorities with a sense of urgency.
• Strong knowledge of Brazilian labor law, compliance, and HR best practices.
• Clear communicator with a collaborative mindset.
• Adaptable, curious, and motivated to build and improve processes.
• Comfortable working onsite 4 days per week in São Paulo.

• Deep dive into details: Professionals who are not content with superficial answers and dive deeply into the details to uncover root causes and optimal solutions.
• Team first: A low need for individual recognition, always prioritizing collective results over personal credit.
• You thrive with ambiguity: Exceptional ability to tackle open-ended problems in unstructured environments, turning chaos into structured innovation.
• Adaptability: Willingness to learn, mentor, lead, and follow as the situation demands, fostering growth at all levels.
• Urgency: A disproportionate sense of urgency in execution, while keeping scalability and the creation of replicable processes in mind to ensure long-term success.
• Curiosity: Genuinely curious individuals who can quickly learn difficult concepts and apply them effectively.

Topsort is an equal-opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
