Chief of Staff

Chief of Staff (CEO) 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). Responsibilities Work closely with the CEO and leadership to execute on the biggest (and smallest) priorities at Arch. Help the CEO and Arch do more – pick up ideas and turn them into initiatives, run projects, propose solutions, and generally think 2 steps ahead. Grow the Arch business – help Arch reach, build relationships with, and close key stakeholders. Identify and reduce efficiency blindspots and operational bottlenecks; spearhead improvements that ultimately help Arch scale faster. Support the CEO in formulating and implementing strategies to meet revenue goals and drive business growth. Oversee strategic business initiatives, from development through successful execution, under the guidance of senior leadership and department heads. Execute on hundreds of other priorities and tasks that we haven’t yet defined. Serve as a force multiplier for the CEO: triage inbound requests, decide what to take on, and ensure top priorities move forward. Turn ambiguous asks into clear, repeatable processes: document workflows, operationalize insights, and reduce blind spots. Execute small but critical tasks with accuracy—nothing is beneath you, and the bar for quality is high. Qualifications Want a fast‑paced, hands‑on learning experience to deepen your expertise in wealth and asset management. Have 4‑8 years of experience working for a top investment bank, consulting firm, or private equity firm. Startup/portfolio company operating experience is a nice‑to‑have. Can context switch quickly, between cranking out an Excel model / building a deck, to meeting with a high‑profile client or partner. Are a low‑ego, highly intelligent, quick learner eager to roll up your sleeves and tackle any task—even though this is not an admin assistant role, no task is too small. Can juggle and prioritize dozens of things at a time; you’ll be integral in executing on some of the biggest (and smallest) priorities of the firm. Thrive in ambiguity, adapt quickly to new opportunities, and take initiative to get things done. Have exceptional communication, organizational, and problem‑solving skills with a proactive problem‑solving attitude. Know that a high‑growth company often means solving problems at 10 pm, and that excites you. Have financial fluency—can read a balance sheet, interpret financials, and build lightweight models. Thrive in an environment where priorities shift quickly and nights/weekends are sometimes part of the work. Location and work style All of our full‑time roles are based onsite at our New York City office, where our team thrives on in‑person collaboration and dynamic teamwork. Being onsite daily enables us to build strong connections, collaborate effectively to solve challenges, and foster an engaging environment focused on shipping product and delivering exceptional service to our clients. We encourage applicants currently located in or willing to relocate to the NYC area to join us in this exciting, hands‑on workspace. Benefits Strong Team – You’ll be backed by a strong team that consistently exceeds client expectations and ships new products quickly. Your work is high impact – Being part of a small team means you have real responsibility and impact from day one. You'll be involved in discussions that drive the growth and direction of our platform from the very beginning. Product Market Fit – We have strong product market fit, exceptionally low churn, and have grown mostly organically through word of mouth. Team community and camaraderie – We have enormous trust in each other and always do what we can to support one another. We're always ready to step in to help. Great office – We’ve invested in a great space for the Arch team to come together, at 18th and Park in Manhattan (the old Buzzfeed / NYT headquarters). Lunch is on us – Grab lunch on us while you’re in the office and take a break to laugh, brainstorm, or just hang out with your teammates over a meal. #J-18808-Ljbffr
