About The Team
Roundtable was founded by an experienced and well-matched team:
Evan

Simon
(CTO) who has been an entrepreneur for more than 10 years now.

About The Role
We are looking for a highly skilled
Senior Software Engineer
to join our tech team.

As a small team, collaborative building is at the core of how we operate—not just within the engineering team but across all departments. We are developing a product that offers an incredible opportunity to co-invest in the Private Equity sector. To achieve our vision, we need to establish both a premium brand and platform.

As our tech team continues to scale, you'll wear many hats. Your responsibilities will include:

Collaborating closely with the team on product strategy, assessing the effort required for various features, and making key technical decisions

Supporting the overall decision-making process and the company's sustained growth

Developing, deploying, and maintaining new features

Conducting code reviews and facilitating knowledge sharing within the team

Technical environment
We handle sensitive financial data, which presents us with the following challenges:

Security
: Data is extremely sensitive, making security a top priority.

Accuracy
: Computations must be exact down to the cent at all times.

Code Quality
: Our tech stack must be robust enough to pass regulatory audits.

Scalability
: Both the data and IT architecture must be functionally and technically scalable. For example, one challenge in our data model involves complex equity flows through multiple layers of intermediaries. The data model must accurately compute ownership and be flexible enough to adapt to different countries' legal contexts.
