Job DescriptionCareer Renew is recruiting for one of its clients a Founding Data Lead - Fintech - this is a hybrid role in Jersey City. Salary range: 180-220K USD base plus benefits. Our mission is to transform how money moves. We believe stablecoins will underpin a new financial fabric, one that is faster, more global, and more efficient than today's siloed systems. That is why we are building AUSD and the stack, a full-service platform that makes issuing, managing, and integrating stablecoins seamless, whether you're a developer, fintech, or institution. With AUSD, stablecoins become programmable, composable, and ubiquitous by default. We believe digital dollars should be a public good: trusted, accessible, and built for real-world utility. Our mission is to drive adoption through customizable, user-friendly on-ramps that make stable, dollar-based value available onchain.

We're a small, mission-driven group of builders who move fast, sweat the details, and hold a high bar for excellence, in product, code, and culture. You'll be joining a tight-knit team that values clear thinking, extreme ownership, and high-velocity decision making. We operate in short feedback loops, support one another without ego, and are deeply motivated by the opportunity to build foundational infrastructure for the future of money. ABOUT THE ROLE As our Founding Data Lead, you'll build the analytics function from zero. You'll own the numbers the company runs on: how we define them, where they come from, and what they mean. High autonomy, high visibility, every part of the business. You'll map data across our stack (onchain, product, financial, operational) into a coherent picture and tell the story of how we run. Customer understanding is where you'll create the most leverage. You'll turn raw behavior into the insights that shape how we grow, where we invest, and what we build next. You'll stand up self-service analytics so every team moves faster on its own, partner with engineering to raise the ceiling on what our data can do, and bring product analytics to life across the surfaces that matter. BASIC QUALIFICATIONS 5+ years of experience in analytics, business intelligence, or data engineering, ideally as an early data hire at a high-growth startup. Strong SQL. You can write complex queries across joins, window functions, CTEs, and subqueries without thinking twice. Experience building and maintaining dashboards and metrics frameworks (Metabase, Looker, or similar). Ability to translate messy business context into clean data models. Comfort working with high-volume event data and the tooling to process it efficiently (Spark, Databricks, ClickHouse, or similar). Clear communication. You can present findings to an exec team and make data-driven recommendations that stick. Working knowledge of data orchestration tools (dbt, Airflow, Dagster, Prefect, or similar). Proficiency with a product analytics platform (Amplitude, Mixpanel, PostHog, Heap, or similar). PREFERRED QUALIFICATIONS Experience with blockchain data: onchain indexing, subgraphs, multi-chain analytics, or DeFi protocols. Background in fintech, payments, or financial services.

Experience with PostgreSQL or other relational databases. Familiarity with cloud platforms (AWS, Azure, or GCP) and containerization technologies (Docker, Kubernetes). Working knowledge of version control (Git), CI/CD pipelines, testing, and monitoring/observability tools. Strong communication and collaboration skills with both technical and non-technical teams. NICE TO HAVE Knowledge of query optimization and database performance tuning. Familiarity with concurrency control, distributed systems, and database transactions. Experience working on distributed systems and optimizing them for scalability and performance. Familiarity with event-driven architectures and messaging patterns (e.g., pub/sub, queues, streaming). Exposure to job queues, caching services, and data pipelines. Understanding of security best practices and a commitment to correctness in financial systems. Experience building and launching a product from zero to one. Background or interest in financial systems, payments, or blockchain/crypto technologies is a plus. THE HIFI CODE This is how we operate. Not aspirational — actual. Ownership If you touch it, you own it. Speed We bias toward motion. Clarity Confusion is a signal to act. Standards Quality matters always. Truth We value directness without drama. COMPENSATION & BENEFITS The expected salary range for this role is $135,000 - $160,000 USD. However, the starting base pay will depend on a number of factors including the candidate’s location, skills, experience, market demands, and internal pay parity.

Who We Are Solana is a high-performance blockchain that can deliver a fast and friendly user experience, without sacrificing security. Solana Labs, Inc. ("Solana Labs") is a technology company that builds products, tools, and reference implementations that can be used on the Solana blockchain. Location: Remote (US or EMEA time zones) Type: Full-time Level: Senior IC Solana Mobile is building the mobile platform for digital assets on Solana. We recently launched Seeker, a digital asset–first phone featuring Seed Vault, a hardware-backed security system for wallets, along with our own wallet and the dApp Store, a mobile distribution platform for apps built by the ecosystem of Solana developers, and the Solana Mobile Stack (SMS), which enables phone manufacturers to deliver these products on their own devices. We don't just provide infrastructure. We build the full stack across hardware, software, and platform services to deliver seamless, secure, and performant digital asset experiences on mobile. Our backend systems power the dApp Store, wallet services, event tracking, both on-chain and within apps, on-chain transaction systems such as staking, and the APIs that developers and users rely on every day. We're a lean, high-agency team. Engineers here own real scope: there's no large org to absorb the slack, and the decisions you make show up directly in the product. That also means we move fast and expect people to operate with a high degree of autonomy. We actively lean into AI-assisted development as a way to keep overhead low and give every engineer more leverage. That's not specific to any one role, it's how we work. We expect engineers to experiment with AI tools, integrate them into their own workflows, and share what works. A lot of what makes us effective is how we work, and there's meaningful room to improve.
