Location: Remote - European Based Candidates

Remote | Full-time

Compensation: Competitive

We are hiring on behalf of our client who is focused on building institutional-grade DeFi operations infrastructure. They are seeking a Senior Operations Engineer. This organization develops the systems, automations, and security layers required to make on-chain asset management reliable at scale. Operating across Ethereum, Arbitrum, and multiple other chains, the client manages vaults, multisigs, and treasury systems where precision is paramount.

This is not a "build-and-hand-off" role. The successful candidate will own the full lifecycle of critical automation infrastructure—from architecture and implementation to monitoring, failure handling, and continuous hardening. This individual will be responsible for the reliability, security, and observability of systems where the standard is absolute: operational errors result in real financial loss.

Key Responsibilities

About LawnStarter

LawnStarter is the nation's leading on-demand marketplace for lawn care and outdoor services, with over $100M in annual bookings. We connect homeowners with vetted local service professionals (Pros) who handle everything from weekly mowing to pool cleaning. We're profitable, growing 30%+ YoY, and expanding beyond lawn care to become the one-stop shop for all outdoor home services.

About the Pro Experience Team

Our marketplace only works when Pros succeed. We have 10,000+ active service providers across the country, and their quality directly determines whether customers stay or churn. The Pro Experience function owns everything that helps Pros get better at their jobs and more engaged with the platform—gamification, training, and the feedback loops that drive continuous improvement.

This is a new function. You'd be the first dedicated hire focused on Pro success and engagement.

The Role

You'll own the programs that help Pros progress from new signups to high-performing Gold and Platinum tier providers. This means designing and running gamification programs, building training initiatives, and partnering with Support to improve the Pro experience.

What makes this role different:

- You're building the function. You'll own it end-to-end and shape what Pro Experience means at LawnStarter.

Senior Product Manager (Crypto-Native Payments)

Location: Europe or up to GMT-3

Compensation: $90K - $110K

We are the global leader in crypto commerce, enabling millions of users across 180+ countries to use cryptocurrency for everyday needs—from gift cards and mobile top-ups to subscriptions and bill payments. For over a decade, we have operated profitably as a distributed team of 90+ people who believe that crypto should be money for everyday use.

As the market shifts from speculation to real-world utility—driven by stablecoin salaries, DeFi yield, and airdrop proceeds—we are looking for a Senior Product Manager to bridge the gap between complex onchain mechanics and seamless consumer experiences. You will join a focused squad of 5-7 engineers and designers in a high-agency, low-meeting environment where product decisions are made close to the work.

What You’ll Do:

Quant / Trading Engineer

Location: US remote preferred, open to Europe for strong candidates

Compensation: Competitive

We are building a foundational layer for the next generation of financial markets: perpetual markets based on onchain economic activity. Instead of merely pricing assets or narratives, our platform allows traders and autonomous agents to take directional exposure to the growth or decay of applications, protocols, and infrastructure within the onchain economy.

We deploy directly into the Hyperliquid ecosystem, optimizing discovery and execution through our dedicated application. As a member of our early-stage team, you will work at the intersection of quantitative finance, crypto market structure, and high-performance onchain data systems.

Your mission is to build the signal layer and APIs that make autonomous trading agents materially more effective. You won’t just be moving data; you’ll be converting raw market behavior into high-fidelity, agent-readable signals.

Smart Contract Engineer (EVM + Rust)

Location: European timezones

Compensation: Up to £65 per hour

We are looking for a highly skilled Smart Contract Engineer with deep expertise in both Solidity (EVM) and Rust to join our elite engineering team at MLabs. In this role, you will be subcontracted to work directly with one of our premier clients—leading innovators in the DeFi space—building next-generation financial infrastructure on Base, Arbitrum, and other EVM-compatible networks.

As a bridge between the smart contract layer and high-performance systems, you will architect, develop, and secure complex DeFi protocols. You aren’t just writing code; you are building the "money legos" of the future, ensuring they are gas-efficient, battle-tested, and capable of handling significant TVL (Total Value Locked).

Staff Quantitative Engineer (Onchain Market Primitives)

Location: Remote - US remote preferred, open to Europe for strong candidates

Compensation: Competitive

About the Company We are building a foundational layer for perpetual markets centered on onchain economic activity. Instead of pricing speculative assets or narratives, our platform allows traders and autonomous agents to take directional exposure to the growth or decay of the onchain economy—including protocols, infrastructure, and capital flows. Our markets are deployed directly into the Hyperliquid ecosystem, with discovery and execution optimized through a dedicated application suite. This is early, foundational work at the intersection of quantitative finance, crypto market structure, and onchain data systems.

Role Overview We are seeking a Staff Quantitative Engineer to own the design and evolution of our core market primitives. This is not a research-only or support role; you will own markets end-to-end, from first-principles design and specification to post-launch iteration based on real trading behavior. As a technical lead and thought partner to the founders, you will set the standard for how we design indexes, oracles, and market integrity systems.

What You’ll Own

Senior Data Engineer (Monitoring & Parameter Systems)

Location: Porto, Portugal (Full-Time)

Category: Engineering / Data Science

Compensation: $140K - $300K

We are on a simple mission: to make it possible for anyone with a digital wallet to trade stocks, commodities, currencies, and crypto with full transparency. We are replacing the opaque, offshore brokerage model with a transparent, permissionless trading stack built entirely on-chain. Every trade, deposit, and withdrawal on our platform is verifiable through open, auditable code.

To date, we have raised $27.9M+ from top-tier investors including General Catalyst, Jump, Susquehanna (SIG), Alliance DAO, and Balaji Srinivasan.

We are seeking a Data Engineer (Monitoring & Parameter Systems) to architect and operate the analytics, observability, and parameter-proposal infrastructure that keeps our protocol safe and economically sound. You will serve as the critical bridge between protocol mechanics—such as fees, spreads, and liquidations—and production-grade data systems. Your mandate is to translate complex economic models into reliable pipelines and monitoring services that ensure the protocol remains healthy across all markets.
