Trading Engineer - Execution

IMC

We are looking for a multi-talented and passionate Trading Systems Engineer to join our execution development team. In this role, you will take ownership of systems that sit directly in the critical path of live trading, handling everything from hardware and network connectivity to application performance and exchange interactions. This is not a pure support role — and it’s not purely project-based engineering either. It’s intentionally both. You will split your time between: * Operational support of live trading systems, ensuring stability and rapid resolution of production issues.  This portion of the role is fast-paced, highly visible and requires strong troubleshooting instincts, clear communication, and the ability to remain calm under pressure.  If you enjoy solving real-time problems and seeing immediate impact from your work, this is for you. * Project-based engineering work, improving the reliability, performance, and automation of those same systems.  The goal is simple: fewer incidents, faster recovery, more proactive monitoring, and stronger systems over time. We believe production ownership and engineering improvement go hand in hand — the best way to improve a system is to deeply understand how it behaves under real-world pressure. Our execution systems are fundamental to our success and require dedicated ownership to ensure continuity throughout the trading day. You will play a key role in both optimizing today’s trading and building a continuously better platform for tomorrow. You’ll join a team of experienced engineers committed to rigorous operational excellence and continuous improvement, with a high degree of responsibility over complex, real-time system interactions across trading and technology. Your Core Responsibilities: * Participate in structured support rotations to provide real-time coverage for critical execution systems * Ensure continuity of trading operations, prioritizing and resolving system issues with urgency and composure * Diagnose novel production incidents, often coordinating across trading, development, infrastructure, and external exchanges * Monitor system performance and proactively identify risks before they impact trading * Build automation tools for system orchestration and operational efficiency * Eliminate recurring issues through root cause analysis and durable fixes * Partner with technology and trading teams to refine and deploy system architecture * Enhance monitoring, observability, and resiliency * Support and optimize core market connectivity Your Skills and Experience: * Passion for problem solving and new technologies. * 2-5+ years of experience in Site Reliability Engineering, Systems Integration, Production Engineering, or a related role in a heavily on-prem environment * 2-5+ years of hands-on experience with Linux operating systems, network configuration, and server management * Strong understanding of network fundamentals, including routing protocols, TCP/UDP, multicast, network offload, and kernel bypass technology * Proficiency in Python and Bash * Demonstrated curiosity and hands-on experimentation with technology—whether through personal projects, home labs, open source contributions, or deep-dive exploration of operating systems and networking * Bachelor’s degree in Computer Science, Information Technology, or related engineering discipline (or equivalent practical experience) Preferred Experience: * Experience with MySQL, MongoDB, and NoSQL technologies What You'll Gain: * Deep exposure to cutting-edge, low-latency trading infrastructure * Direct impact on live trading—your work matters immediately * Broad technical growth across hardware, networking, systems, and application layers * Collaboration with elite traders and engineers * Ownership and autonomy over critical systems The Base Salary range for the role is included below. Base salary is only one component of total compensation; all full-time, permanent positions are eligible for a discretionary bonus and benefits, including paid leave and insurance. Please visit Benefits - US | IMC Trading for more comprehensive information.

Founding Rust Engineer

Twin Labs

FOUNDING RUST ENGINEER PARIS OR REMOTE (EUROPE) ABOUT TWIN Twin is building fully autonomous AI agents that run real business operations. You give a goal. Twin figures out the steps. It executes them end-to-end through APIs when they exist and through the browser when they don't. This is not another chatbot. This is not another workflow builder. We are building systems that can operate companies. In the first months of beta, users have already deployed more than 100,000 agents running lead generation, customer support, operations, trading systems, e-commerce workflows, reporting, and entire service businesses. Twin was founded by Hugo Mercier , CEO (founder of Dreem, $60M raised, 150+ employees, acquired) and João Justi, CTO (cryptography, compilers, virtual machines, distributed systems, ex-Zama) but also Julius de Bruijn, creator of Tiberius (3.3M downloads) and Patrick Tourniaire We raised a $10M seed round led by LocalGlobe and are building with a small team of senior engineers. WHY JOIN TWIN? * Work on one of the hardest problems in software: making AI agents reliable enough to run real businesses. * Build from first principles: many of the core abstractions don't exist yet. * Small team, massive ownership: your decisions directly shape the product, architecture, and company. * Rust at the core, product at the center: not infrastructure for infrastructure's sake. * Design systems for both humans and AI agents: a new software paradigm that barely exists today. * Early enough to matter: every engineer has outsized impact on what Twin becomes. WHAT YOU'LL WORK ON Most AI companies are focused on generating text or code. We are focused on making AI systems reliably execute real work. You will work on some of the hardest problems in autonomous agents: * Browser execution at scale * Low-latency communication between agent subsystems * Reliable orchestration of long-running workflows * Memory systems that improve over time * Self-healing execution architectures * Agent infrastructure that survives failures * Product features used directly by customers * Internal systems that AI coding agents can understand, operate and extend Part of the challenge is not simply writing software. The challenge is designing systems that remain understandable and modifiable by AI coding agents themselves. The way we build software internally increasingly assumes that both humans and coding agents will interact with the codebase. WHAT WE'RE LOOKING FOR We're not looking for a "Rust developer". We're looking for engineers who can own problems from idea to production. You should probably have: * Significant production Rust experience * Strong systems thinking * Experience building and operating real products * High autonomy * Ability to navigate ambiguity * Interest in AI systems and LLMs * Curiosity across the entire stack You may come from: * Infrastructure * Databases * Distributed systems * Developer tools * Browsers * Networking * Compilers * Runtime systems * AI infrastructure What matters most is your ability to build robust systems and make good product decisions. WHAT TENDS TO WORK WELL HERE The engineers who thrive at Twin usually: * Ship fast * Take ownership without waiting for permission * Care deeply about product outcomes * Prefer building over discussing * Enjoy working close to users * Can move between infrastructure and product work Many of the strongest engineers we know have backgrounds as founders, open-source maintainers, systems engineers, or product-minded infrastructure builders. WHAT WON'T WORK This role is probably not for you if: * You need detailed specifications before starting * You prefer working on isolated technical components * You only want to work on backend infrastructure * You are uncomfortable making product decisions * You dislike ambiguity * You expect large-company processes EXAMPLES OF BACKGROUNDS WE FIND EXCITING * Engineers who built widely-used open-source infrastructure * Early engineers from highly technical startups * Systems engineers who became product builders * Founders who built technical products from scratch * Developers who combine deep technical expertise with strong product intuition COMPENSATION Package 200 - 250 K We're building for the long term and want people who think like owners. LAST WORDS The software industry spent the last decade building SaaS. The next decade will be about autonomous companies. We believe AI agents will not just assist people. They will operate businesses. If that future sounds inevitable to you, we'd love to talk.
