About Arch

At Arch, our mission is to build world class financial products for the next generation of investors.
In January 2023, we launched our first product, cryptocurrency-backed loans. This has provided our users with access to credit while retaining the upside in an asset class that we believe is playing a crucial role in modernizing the outdated financial infrastructure of today. Today, our customers include individuals across the country, high net worth individuals and family offices, small and medium business owners, Bitcoin miners, hedge funds, energy companies and publicly traded corporations.
This is just the initial phase of a longer journey towards becoming a single financial hub for all our users’ assets. A lot of work remains to be done to realize our mission, and we’re looking for people enthusiastic to march towards it with us. By joining us at this stage you’re not only looking to build products, but also to help build a company.
Arch is a close-knit team from best-in-class fintech and consumer companies including Brex, Snapchat, Google, Tinder, Bridgewater Associates and more. We are well funded with $7.75m in backing from top-tier venture capitalists in both traditional finance and crypto including Galaxy Digital, Castle Island Ventures, Morgan Creek Digital, and more. We’ve also raised a $XXXm scalable loan financing facility.

About the role

Arch is looking for a Senior Software Engineer to join our small, ambitious team and help build the future of financial infrastructure. As an early engineer, you’ll play a foundational role in designing, developing, and scaling new products — from Zero to One.
This is a high-impact role that involves everything from collaborating with users to deeply understand their workflows, to architecting backend systems, integrating with vendors, and building resilient, observable software. Your technical decisions will shape our platform, development practices, and long-term scalability.
We especially value experience in fintech — whether building lending platforms, financial data infrastructure, payments, or anything where trust, accuracy, and reliability are paramount.

What you will do:

Define and scope new products alongside engineers, designers, and business stakeholders
Architect scalable services, APIs, and frontend applications
Own end-to-end execution of features — from idea to deployment and iteration
Collaborate closely with design to create clean, intuitive user experiences
Evaluate and adopt the best-fit tools, frameworks, and vendors
Develop internal tooling that accelerates our pace and increases reliability

Qualifications

5+ years of software development experience at a top tech company or fast-moving startup
Strong proficiency in TypeScript, React, and Next.js (or similar frontend frameworks)
Demonstrated ability to independently drive complex projects to completion
Strong systems thinking and an ability to break down complex product problems
Excellent communicator, comfortable working across disciplines and with external partners
Passion for building in the open: rapid prototyping, iteration, and user feedback
Ownership mindset: you thrive in ambiguous environments and don’t wait to be told what to do
Strongly preferred: Experience building fintech products — lending, payments, trading, or financial data systems
