Join Us and Lead the Real Estate Revolution!

At 99 Group, we're on a mission to revolutionise the real estate industry by seamlessly integrating cutting‑edge technology and innovation. If you're excited to be at the forefront of this transformation and are ready to tackle the industry's challenges head‑on, we want you to be a part of our dynamic team.

Your Role: Technical Lead

We are looking for a Technical Lead who can guide a cross‑functional engineering team while remaining deeply hands‑on. This role will involve around 70% hands‑on engineering and 30% team leadership, with a strong emphasis on backend architecture, cloud‑native systems, and building scalable solutions. You will oversee both backend and frontend engineers, ensuring strong technical direction while staying involved in day‑to‑day development.

Responsibilities

• Design, develop, and review backend services, APIs, and overall system architecture with a cloud‑native mindset.
• Work closely with engineers to diagnose and resolve scalability challenges, from service bottlenecks to database performance issues.
• Provide technical guidance and mentorship to backend and frontend engineers, helping them grow and operate more effectively.
• Set technical direction, ensure high engineering standards, and drive best practices in a pragmatic, context‑aware manner.
• Act as a multiplier by elevating the team’s technical capabilities, improving collaboration, and fostering a culture of ownership.
• Partner with Product Managers and Engineering Managers to plan, align, and deliver projects that meet business objectives.
• Participate actively in code reviews, technical design discussions, and solutioning sessions.
• Balance hands‑on contributions with leadership responsibilities, ensuring smooth execution while supporting team members.

Requirements

• 7+ years of professional software engineering experience, with at least 2 years leading or guiding a team.
• Strong backend engineering background, with working knowledge of frontend technologies.
• Experience building cloud‑native, scalable, distributed systems.
• Ability to incrementally solve scalability problems across all layers of the stack — application, service, and database.
• Pragmatic mindset: understands that technical decisions involve tradeoffs and avoids blindly applying “best practices.”
• Strong communication, mentorship, and technical guidance skills.
• Ability to work effectively with cross‑functional teams and stakeholders.

Good to Have

• Experience with Golang and JavaScript/TypeScript, though other language backgrounds are welcome.
• Familiarity with modern frontend frameworks and microservices architecture.
• Willingness to learn and adapt quickly, especially in adopting Golang for backend work.
