Job Description:

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: We’re hiring a Chief of Staff to the CEO to take on the work - big and small - that drives Arch forward. You’ll act as an extension of the CEO, picking up strategic projects, producing insights from data, unblocking operational bottlenecks, and ensuring the company moves faster and with more focus. No two days will look the same. You’ll combine strategic thinking with tactical execution, moving from building a model or board deck to coordinating an investor intro or running down a legal item. If you’re low-ego, detail-obsessed, and excited by intense, hands-on work at a high-growth company, this is the role. This is likely a 2 year role – after this role, we’ll look to deploy you functionally into the business (i.e. find a function or larger project to run) At Arch you will: Work closely with the CEO and leadership to execute on the the biggest (and smallest) priorities at Arch Help the CEO and Arch do more – your role is to pick up ideas and turn them into initiatives, run projects, propose solutions, and generally think 2 steps ahead Grow the Arch business – helping Arch reach, build relationships with, and close key stakeholders.
