Job description

Moonshot is the “Robinhood for DeFi”—an iOS and Android app that lets anyone trade cryptocurrencies on-chain through a user-friendly interface.

Since our launch in July 2024, we’ve attracted 2M+ users.

Our mission: Make moonshots possible for everyone.

Our vision: Make a world where life-changing financial outcomes are within everyone's reach.

Everyone on our team is both a decision‑maker and an implementer—united by a sense of urgency and driven by the conviction that our work can transform global finance. If you thrive on curiosity, welcome tough challenges, and aspire to leave a meaningful mark on the world, Moonshot is the place for you. You’ll run toward the hardest problems alongside high‑caliber teammates who consistently push each other to excel and who share your dedication to shaping the future of decentralized finance.

This role is full‑time, preferably located in NYC. Open to remote for the right candidate.

The Opportunity

As a Staff Backend & Platform Engineer at Moonshot, you’ll own some of the most critical systems in our stack: identity and access, funds movement and ledgering, and the blockchain infrastructure that powers our on‑chain trading. This role is similar to staff engineers at leading crypto wallets and exchanges who own authentication stacks, key management, and high‑scale financial backends. You’ll design, build, and operate systems that must be both highly reliable and extremely secure, enabling product teams to move quickly on a solid foundation.

What You’ll Do

  • Design, build, and operate Identity & Access Management services:

    • Authentication flows, sessions, device trust.

    • Authorization and entitlements (roles, permissions, policies).

    • Security controls such as MFA and key management (working with security teams).

  • Own financial operations systems:

    • Transfers and payments orchestration.

    • Ledgering and reconciliation flows.

    • Limits, risk controls, and transactional correctness.

  • Build and maintain blockchain infrastructure:

    • Node and RPC management.

    • Transaction submission, monitoring, and retry logic.

    • Indexing and streaming of on‑chain data into internal services and data stores.

  • Define and uphold reliability and observability standards:

    • SLOs and error budgets for core services.

    • Dashboards, alerts, runbooks, and incident management practices.

  • Lead large, cross‑functional technical projects from design through rollout, collaborating with Product, Security, and Ops.

  • Mentor and guide other engineers, contributing to engineering standards, design reviews, and documentation.

  • Stay close to industry best practices in auth, key management, and secure infrastructure for crypto and trading.

What We Look For in You

  • 5–12+ years of backend or product or platform engineering, including experience with high‑scale, high‑availability systems in fintech, crypto, or similar domains.

  • Deep expertise in at least one of:

    • Identity & access / security engineering

    • Financial systems / ledgering / payments

    • Blockchain infrastructure / on‑chain data

  • Strong experience designing and operating distributed systems (datastores, queues, streaming, background workers).

  • Track record driving architecture decisions and seeing them through implementation and adoption.

  • Strong operational mindset: monitoring, on‑call, incident response, and postmortems.

  • Excellent collaboration skills, especially with Product, Security, and Ops.

Nice to Haves

  • Experience with Flutter, React Native, React, Headless CRMs

  • Experience with Go, Rust, Solana

  • Experience with Google Cloud or Amazon Web Services

  • Experience with crypto wallets, exchanges, or onchain protocols including DeFi, L2s, ZK

  • Exposure to data warehousing and analytics for financial reporting.

  • Contributions to open‑source projects.

Location

  • NYC preferred (with periodic in‑person sprints).

  • Remote-friendly within the United States and Canada; travel ~1wk/quarter

Compensation & Package

  • Competitive salary and meaningful equity.

  • 5% 401(k) match.

  • Health benefits with employer‑covered premiums, plus life insurance coverage.

  • One‑time office setup stipend.

  • Flexible PTO.
