Gemini
Senior Software Engineer, Money
$140,000–200,000 (New York)
New York / Miami / Remote (USA)
Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. The Money Team owns the financial infrastructure that underpins every dollar and crypto asset that moves through Gemini — the ledger platform (system of record for all crypto and fiat balances, settlements, fees, rewards), the payments services, and the reconciliation pipelines that connect Gemini to banks, payment rails, and external partners.
☑️ Responsibilities
-Design, develop, deploy, and support ledger and payments services that accurately record all crypto and fiat money movement across the platform
-Build and evolve bank settlement and reconciliation pipelines that connect Gemini to external payment rails and banking partners
-Apply sound engineering principles to identify correctness, consistency, and operational risks — and implement safeguards in software before they become incidents
-Partner with finance, reconciliation, and treasury teams to understand real-world workflows and translate them into robust, auditable system behavior
-Design scalable APIs and data models that support new transaction types, products, and regulatory requirements without increasing operational burden
-Write well-tested, production-grade code that other critical systems depend on
-Monitor and communicate the health of ledger and payment systems, proactively identify issues, and participate in incident response and remediation
-Mentor teammates; participate in on-call rotations as needed
☑️ Minimum Qualifications
-5+ years of experience building backend systems in a production environment
-Strong experience designing and operating distributed, stateful systems where data integrity is critical
-Proficiency in at least one backend language — we primarily use Scala and Go, but are open to candidates willing to learn
-Experience with unit testing, integration testing, and CI/CD pipelines
-Familiarity with cloud-based infrastructure (AWS, GCP, or Azure)
-Ability to reason about and debug complex system behavior across services and data stores
-Strong communication skills and the ability to work effectively with cross-functional partners

Ethena Labs
Senior/Staff Software Engineer
Remote
Ethena builds investment products that benefit from the speed, programmability, and compliance advantages of blockchain tokenization. This new engineering team owns a money-movement product built on top of Ethena's stablecoin infrastructure — payments, payouts, deposits, transfers, and reconciliation — plus the app-facing APIs and authentication backend the native mobile app depends on. This is a senior IC role with real design authority over the backend.
☑️ Role Responsibilities
-Design, build, and own complex backend systems for a high-usage consumer app
-Own the app-facing API contract as a product: versioned, backward-compatible endpoints with client idempotency keys, a consistent error model, and clean pagination, built in partnership with the iOS team
-Own the authentication and authorization backend, including the passkey/WebAuthn relying party, session/token lifecycle, and authorization enforcement at every API boundary
-Defend the auth surface against abuse through rate limiting, anomaly detection, and secure handling of PII and secrets
-Set patterns, tests, and documentation so the backend can be safely extended by any engineer
-Trace and document money-paths end-to-end, from API through wallet/executor/submitter/indexer, event streams, and on-chain settlement
-Ship fast, test-first, with test-driven and behaviour-driven development
☑️ Required Skills and Experience
-Proven experience building and operating backend systems that move real money in production — payments, exchange/settlement, lending, banking, or crypto
-Experience designing and owning client-facing APIs consumed by a mobile app at scale: contracts, versioning, idempotency keys, error models, pagination, rate limiting
-Experience building or operating an authentication/authorization backend — OAuth2/OIDC, JWT session/token lifecycle, RBAC/ABAC scopes, MFA/step-up — ideally a WebAuthn/passkey relying party
-Hands-on integration with real financial third parties end-to-end (card issuing, KYC/fiat ramp partners, or payments/settlement providers)
-On-chain settlement literacy from the backend — nonces, gas, reorgs, RPC failure, confirmation depth
-Strong TypeScript (or a fast path from Go/Kotlin/Rust/Java), with Postgres, an event/queue system (NATS/Kafka/SQS-class), and gRPC at production scale
-A test-first culture — BDD/integration testing with real dependencies — and fluency with agentic development workflows (Claude Code, MCP)

Keyrock
Senior Data Engineer
Remote (hubs: London / Brussels / Singapore)
Since 2017 Keyrock has grown into a leading market maker in the digital asset space — 250+ team members, 42 nationalities — with services spanning market making, options trading, high-frequency trading, OTC, and DeFi trading desks. The Central Data Team is a few months old and is building the Keyrock Data Platform to give Keyrockers and the AI agents working alongside them the data and context they need to act fast and autonomously.
☑️ What You'll Do
-Build streaming and batch pipelines that ingest, normalise, and distribute market, trading, and portfolio data, resilient to feed and exchange failures
-Build the self-serve tooling (SDKs, patterns, templates, AI agents) so other teams publish, consume, and build on data products without waiting on the team
-Own data contracts and schema evolution
-Design the lakehouse and time-series layer around consumer query patterns
-Build and evolve the Data Governance and Data Quality Framework: stale-feed detection, schema validation, range checks, idempotent writes, lineage, ownership, self-healing
-Build the derived analytics the business runs on: cross-exchange spreads, VWAP at depth, order book microstructure, portfolio views, exposure, performance
-Make observability, cost, and performance first-class from day one
-Treat infrastructure as code (Docker, Terraform, CI/CD)
☑️ What We're Looking For
-8+ years of building production data systems that other people rely on
-Strong proficiency in Python and SQL, able to reason about what the engine is doing
-Strong understanding of data modelling for both streaming and analytical workloads
-Designed and operated streaming systems on Kafka, Redpanda, MSK, or Kinesis, with opinions about partitioning, consumer groups, offsets, and schema registries
-Used a time-series store in production (ClickHouse ideally; TimescaleDB, QuestDB, or similar), can talk about table design as a function of query patterns
-Worked with a lakehouse architecture; reason about table layout, partitioning, and compaction
-Build for self-healing and idempotency; Docker, Terraform, and CI/CD are how you work
-Understand financial market data: order books, trades, reference data, portfolios, exposures. Crypto, TradFi, or both a strong plus
-Nice to have: Apache Iceberg or Delta Lake; DataHub or similar; Rust
