The Markets Team sits at the intersection of institutional asset issuance and onchain liquidity operations within the M0 ecosystem. The team operates the infrastructure that transforms real-world collateral, such as U.S. Treasuries or tokenized money market funds, into M0-powered stablecoins: programmable, composable digital dollars used by builders across DeFi and beyond. The team operates and grows M0's liquidity orchestartion layer and partner flows across the growing network of issuers and stablecoin partners. The Markets Team is a critical bridge between institutional-grade financial infrastructure and the onchain economy and is now scaling into the future.
This is a hands-on operations role with a strong emphasis on governance, risk, and compliance. You’ll manage core workflows from minting and redemption to onboarding, reconciliations, and AML operations, while building the structures that ensure MXON operates with institutional rigor and audit and licensing readiness.
You’ll join at a formative stage where your ideas and systems design will directly shape next-generation financial infrastructure. We’re looking for someone who combines the discipline of traditional finance with the agility of digital assets, and who thrives on bringing structure to dynamic environments.
Working closely with Finance, Legal, and external partners, you’ll support audit preparation, risk assessments, and compliance planning. The role begins as an individual contributor but offers a clear path to build and lead a team as we scale globally and deepen our regulated footprint.
Based in the Americas (excluding the US) or Asia, this role covers a 11 AM–7 PM PT shift and works closely with global teams across regions.

We are seeking a hands-on Security Engineer who thrives in a startup environment.
You'll work alongside product owners and engineers with the objective to secure the products in Startale's ecosystem. Products include a next-generation decentralized exchange with a fully on-chain order book (Strium), a user-facing application (StartaleApp) and a stablecoin (USDSC). This is a hands-on, technical role. You'll be the person who actively tests our systems, hunts for vulnerabilities, models threats against our products, and works with engineers to close the gaps — not the person who writes policies and generates reports. You'll report to the Security Lead and collaborate daily with Backend, Frontend, DevOps, and Blockchain engineering teams.
Must-have
Strong plus
Domain plus
Decentralized exchanges, DeFi protocols, blockchain security firms, L1/L2 chain security teams, or fintech companies with trading infrastructure. We're also open to strong AppSec engineers from cloud-native startups who have genuine interest in web3.
You're a hands-on security engineer who finds real vulnerabilities, not just runs scanners. You've secured a trading platform or exchange and understand the threats specific to financial infrastructure — order book manipulation, transaction signing, wallet compromise, front-running. You can take a system, map the attack surface, and come back with findings that matter. You write clear reports that engineers act on, and you know the difference between a theoretical risk and a real one. You're comfortable working independently in a fast-moving team where there's no playbook — you write the playbook.

In partnership with SBI Group, we are building a next-generation decentralized exchange (DEX) aimed at bringing the majority of Japanese equities on-chain. Our goal is to create a secure, transparent, and high-performance trading infrastructure capable of supporting institutional volumes while remaining accessible to retail participants. The platform features a fully on-chain order book and is powered by a custom state transition function and consensus layer, purpose-built for low-latency, high-throughput trading.
As the Senior QA Engineer, you will be the quality champion for this system and cover core trading flows, order book behavior, matching logic, and backend services powering execution. As the first senior-level QA on the team, you will own the end-to-end quality strategy with a strong emphasis on automation, ensuring the correctness, reliability, and performance of both API and E2E layers under real-world trading conditions.
This is a hands-on role focused on building robust E2E and API test coverage, not manual testing.
Quality strategy & process: Define and evolve QA standards, release criteria, and quality metrics tailored to a trading platform. Establish best practices for validating execution accuracy, pricing, and API reliability.
Automation (E2E-first approach):
Design, build, and maintain a scalable end-to-end automation framework for the web app, covering critical user journeys.
API testing & validation:
Develop comprehensive automated tests for backend services and APIs. Ensure consistency between API responses and frontend behavior.
Trading logic validation:
Validate correctness of execution paths, price impact, and fee calculations across different trading pairs and liquidity sources.
Performance & reliability:
Drive API-level load and stress testing for high-throughput scenarios. Validate system behavior under peak traffic and degraded conditions (timeouts, partial failures, node issues).
Test data & environment strategy:
Design reliable test environments and datasets (mocked or real blockchain interactions), ensuring repeatability of E2E and API tests.
Cross-team collaboration & leadership:
Work closely with Engineering and Product to define testable acceptance criteria. Take ownership of QA processes, drive automation adoption, and set quality standards across the team.
