Company: 39k Group – India's Largest Crypto Trading Firm

39k Group is hiring a hands-on Quant Developer to help scale and optimize the infrastructure behind our high-frequency crypto trading strategies. This is a technical, high-impact role designed for someone who wants to work closely with traders, solve real-time problems, and build systems that directly contribute to trading performance.

What You'll Do

Build and maintain connectivity to global trading venues, optimizing systems from both software and infrastructure perspectives.
Write internal tools for real-time risk monitoring, strategy control, and operational oversight.
Enhance and maintain the firm's reporting and analytics infrastructure, making PnL and trading behavior more transparent and actionable.
Build customized applications that help solve day-to-day trading and operations challenges — no layers of abstraction.
Manage and operate Linux-based trading machines, handling process tracking, log management, system health, and deployment workflows.
Work with InfluxDB, QuestDB, and similar time-series tools to empower traders and researchers with fast, accurate data access.

How the Role Works

You'll be part of a small, focused team that includes traders, developers, and business leads — working collaboratively with a high degree of ownership. Each team is responsible for its own strategy stack, infrastructure, and performance, offering autonomy and clear accountability. The structure is lean and performance-focused, enabling you to move quickly from idea to impact.

What We're Looking For

3+ years of relevant experience in a trading firm, HFT desk, or infrastructure-heavy quant research role.
Advanced programming skills in Python and C++; familiarity with Rust is a plus.
Experience operating and optimizing Linux systems in production trading or data environments.
Comfort working with tick-level and time-series datasets for research, monitoring, and signal development.
Strong debugging and performance optimization skills, especially in live trading contexts.
Clear sense of ownership and urgency, with the ability to balance technical rigor and trading needs.

Why Join 39k Group

Join the team behind India's largest crypto trading operation, active across major global exchanges.
Work directly with traders, researchers, and decision-makers — no bureaucracy.
Build systems that power live strategies and directly influence firm-wide performance.
Enjoy a hybrid work model (11 WFH days/month) and an outcome-linked compensation structure.
Be part of a fast-moving, execution-first culture where your work drives real PnL.

If you're a pragmatic builder who thrives at the intersection of trading and technology — and you're ready to make your code count — we'd love to hear from you.
