Senior Product Engineer responsible for leading financial systems projects and technical leadership within FinOps team at Moxie.
Responsibilities
- We're looking for a Senior Product Engineer to own and deliver medium-to-large financial systems projects as a core contributor on our FinOps team — building the payments, billing, and financial-operations infrastructure that powers real med spa businesses at scale.
- You'll also be stepping into a broader technical leadership role: participating in Moxie's Engineering Architecture Process, mentoring IC1–IC2 engineers, and helping raise the bar on engineering practices across the team.
- This role is part of FinOps' build-out for H2 2026, and part of a broader shift toward direct-hire engineers in the Americas as we transition off contracted headcount. You'll join a team working on high-stakes financial workflows (Stripe, LayerFi, Cherry, and more), with real ownership over architecture and technical direction from day one.
- This role is fully remote and open to candidates based in Colombia, Brazil, the Dominican Republic, or Chile.
- Own and deliver medium-to-large FinOps projects end-to-end — from design through production — as a hands-on senior IC.
- Build deep expertise in FinOps systems and business context (Stripe, LayerFi, Cherry, and related billing/payments workflows), becoming a trusted technical resource for the team.
- Participate actively in Moxie's Engineering Architecture Process, contributing to and influencing technical decisions within your domain.
- Own at least one team- or domain-level non-project initiative — such as testing standards, documentation, or code review practices — that raises engineering quality beyond your own projects.
- Mentor IC1–IC2 engineers and act as a culture carrier for strong engineering practices, growing toward Staff (IC-4) scope over time.
Conditions
- Above all, we're in this to empower small business owners to own and grow their businesses. Med spa providers depend on financial systems that just work — this role gives you direct ownership over that reliability.
- This is a senior role with real scope and a clear path toward Staff (IC-4): you'll own systems, not just tickets, and help shape how the FinOps team builds.
- We have much left to build. Given the market feedback we're seeing and our team's experience, we believe we're writing the early chapters of a real success story — and this role gets to help write the financial-systems chapter of it.
- Working Hours Core overlap with 9 AM – 5 PM EST (flexible schedules between 7 AM – 8 PM EST).
Other
- At Moxie, we empower ambitious aesthetic entrepreneurs to build profitable, independent practices—without burnout, overwhelm, or guesswork. In just a few years, we've grown from an idea to a global, remote-first team now supporting 700+ practices nationwide.
- Our purpose is simple: to unlock sustainable success for aesthetic entrepreneurs, at every stage of their journey.
- Strong backend engineering experience, including schema/API design, data modeling, and async processing (Python/Django experience a plus).
- Deep PostgreSQL fluency — query optimization, schema design, migrations, and data-integrity patterns.
- Experience building and hardening third-party integrations, ideally in payments or financial systems, with strong attention to failure handling and idempotency.
- A track record of owning medium-to-large, sometimes ambiguous projects end-to-end as a senior IC, including tradeoff decisions and cross-functional coordination.
- Comfort influencing architecture and technical direction beyond your own immediate project scope.
- Experience mentoring engineers and raising the technical bar for a team.
- Excitement for high-ownership, early-stage environments where decisions matter and aren't buried under bureaucracy.
- Frontend: React, TypeScript, Next.js
- API: REST, GraphQL, Hasura
- Backend: Python, Django

- At Moxie, we believe in creating a workplace where everyone feels valued, trusted, and included. Our team lives by our values: act as owners, give more than we take, move with speed and care, and simplify and learn every day.
