About the Company

At Flowdesk, we are building the infrastructure powering the next era of global finance. As a full-service digital asset trading and technology firm, we provide liquidity solutions, OTC trading, and market infrastructure that connect digital assets to global markets with institutional-grade precision, transparency, and scale. Flowdesk combines expertise from traditional finance, algorithmic trading, and blockchain technology to deliver always-on trading capabilities across the digital asset ecosystem. Founded in 2020, we have grown into a global team supporting institutions, exchanges, and token issuers worldwide as the financial system evolves toward tokenized markets. Why join Flowdesk You'll be joining a company operating at the intersection of finance, technology, and crypto - solving complex market problems, building critical infrastructure, and helping shape how digital assets move globally. We move fast, think long term, and work with a strong ownership mindset across engineering, trading, product, operations, and business teams. Our OTC Tech team builds and maintains the systems behind our OTC derivatives trading, working directly with traders and quants. The team is small, so engineers have wide ownership and a direct line to the people using what they build. We are looking for a hands-on Rust engineer with options trading or financial engineering exposure to join the team. Parts of our OTC derivatives stack are quant-heavy, and some libraries are difficult to change safely without deeper domain knowledge. You will be the person who can work confidently in that code. The role remains primarily engineering, not research.

  • ● Quantitative grounding: enough to read, understand and implement pricing and risk models (you will not be expected to design or price derivatives from scratch)
  • ● Experience building production systems in a trading or other high-stakes environment
  • ● Able to work directly with traders: turn their requests into clear requirements, explain technical trade-offs simply, and keep them informed when something goes wrong
  • ● Experience at an OTC derivatives desk, options market maker, or institutional crypto trading firm
  • ● Experience with pricing libraries, volatility surfaces, Greeks, or risk systems
  • ● Experience beyond backend work, such as front-end, internal tooling or data pipelines
  • ● Startup or small-team experience with end-to-end ownership and a fast delivery pace
  • ● C++ background - useful where Rust experience is being built
  • ● Singapore
  • ● Independent and resourceful
