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.

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
