Software Engineer

Our Company

Arch is a Series B financial technology company that automates the management of private investments, improving access, understanding, and the human experience of investing across asset classes. 

Private investments such as venture capital, hedge funds, and private equity, make up roughly 25% of the investment universe. Traditionally, investors, advisors, banks, families, and managers track hundreds of investments in complicated spreadsheets, file folders, and busy inboxes. Not only is this tedious and time-consuming, but it is rife with opportunity for manual data entry errors, inconsistent reporting, and lost information. Enter, Arch.

Arch delivers standardized data, documents, and insights in a single platform, avoiding the need to chase information across dozens or hundreds of ‘portals’. Our purpose is to save investors’ time while empowering them to make more informed investment decisions, leading to better financial outcomes. 

We are a fast-growing, dynamic team of 200+, serving over 400 clients, including several of America’s largest banks, families, and financial institutions. We’ve over doubled the size of the company every year since inception and we are looking to hire in all departments as we scale.

The Role

As a Software Engineer, you'll help develop and scale core components of our platform. Your work will support the automation of complex processes, the launch of new product offerings, and the growth of our infrastructure. This is an important role, as your contributions will directly enable technology that is powering billions in investments and driving meaningful impact for our clients. You'll collaborate closely with fellow engineers, product managers, and other team members to deliver solutions that make a difference in our clients' investment processes.

Your Responsibilities Will Include:

• Contributing to both user-facing interfaces and backend services using modern frameworks and technologies

• Helping develop reusable software components and APIs that connect front-end and back-end systems

• Writing clean, efficient, and reliable code, and learning how to optimize for performance and scalability

• Participating in code reviews and learning best practices from peers and senior engineers

• Assisting in designing and implementing systems that are scalable and maintainable across the stack

• Troubleshooting and fixing issues across front-end, APIs, and databases

• Gaining experience working with multiple programming languages, frameworks, and databases

• Taking responsibility for assigned tasks and features, developing an end-to-end understanding of how they work

Bonus Points If You:
