About Transak
Transak is the leading global on/off-ramp infrastructure for crypto, trusted by over 450 web3 applications. We enable users in 80+ countries to seamlessly convert between fiat and crypto, powering over $60M–$70M in monthly transaction volume.
At the heart of Transak's core engine is our ability to price competitively and execute efficiently across multiple venues - crypto exchanges, DEXs, market makers, and OTC desks - while maintaining robust inventory and treasury systems.
About the Role
We're hiring a Crypto Trading and Pricing Engineer to build and manage the systems that drive our inventory restocking, real-time pricing, and P&L optimization. You’ll design algorithmic trading and pricing engines, integrate with liquidity providers, and ensure we are competitive, capital-efficient, and compliant.
This is a high-impact engineering and trading role that requires hands-on experience with algorithmic trading systems, financial risk management, and low-latency architecture. You’ll own the technical and operational backbone of how crypto inventory is sourced and priced for millions of users globally.
Key Responsibilities
* Design, build, and maintain automated trading systems that restock Transak’s crypto inventory across CEXs, DEXs, OTC desks, and aggregators using APIs and WebSocket feeds.
* Develop an algorithmic pricing engine to quote fiat-crypto and token swap transactions in real time across 80+ countries and 100+ cryptocurrncies methods.
* Maximize profit and minimize slippage, inventory outages, and latency across a $60M–$70M monthly flow while staying within risk thresholds.
* Build systems to monitor real-time price movements, identify arbitrage or spread opportunities, and route orders optimally.
* Implement real-time P&L tracking, exposure monitoring, and inventory accounting systems to support treasury and finance.
* Collaborate with product, engineering, and compliance teams to define pricing logic, markups, FX handling, and fee models.
* Set risk controls and fail-safes to prevent catastrophic losses from faulty strategies or API outages.
* Own dashboards and tooling for pricing visibility, inventory health, and trading performance.
What You’ll Need
* 3+ years of experience in algorithmic trading, HFT, or pricing engineering in crypto, FX, or fintech.
* Proven software engineering skills and the ability to build scalable, fault-tolerant systems from scratch (Python preferred).
* Strong understanding of market structure across CEXs (e.g., Binance, Coinbase), DEXs (e.g., Uniswap, 1inch), and OTC liquidity networks.
* Deep comfort working with WebSocket feeds, trading APIs, and execution management systems.
* Solid grasp of trading concepts: slippage, latency, arbitrage, spreads, inventory management, and risk control.
* Experience modeling pricing and fees and working with treasury capital in a fast-paced environment.
* Data fluency: ability to model, backtest, and analyze pricing logic and performance using Python, MongoDB, or Excel.
Why Join Us
* Own the technical systems powering $60M+/month in crypto trading and pricing.
* Shape the future of how real-time pricing drives conversion and margin in the crypto economy.
* Join a high-growth, well-funded company at the intersection of fintech and web3.
* Work alongside a world-class team across trading, engineering, product, and compliance.
