Company mission
To provide institutional-grade technology that supports the full digital asset investment lifecycle, including liquidity sourcing, price discovery, trading, settlement and portfolio management.
Role
Who you are
- 5+ years of experience building backend systems in Java
- Strong understanding of concurrency, high-throughput system design, and distributed architectures
- Experience developing REST and WebSocket services
- Proficiency with SQL databases and modern development workflows (Git, CI/CD, Jira)
- Experience working in cloud environments (AWS or GCP)
Desirable
- Exposure to Python data libraries (NumPy, pandas)
- Familiarity with portfolio construction, risk modeling, or systematic trading systems
- Understanding of regression techniques, time-series analysis, or constraint-based optimization concepts
What the job involves
- Talos is seeking a Software Engineer to join the Portfolio Engineering team. This team builds the systems that power institutional portfolio construction, optimization, risk modeling, and systematic strategy deployment across digital assets
- The Portfolio Engineering platform integrates directly with the Talos OEMS, enabling clients to design, validate, and execute investment strategies within a unified, production-grade environment. You will contribute to core systems that require correctness, performance, and scalability
- Design and implement core components of the Portfolio Engineering platform, including the backtester, portfolio optimizer, rebalancer, and reporting engine
- Own features end-to-end: requirements definition, technical design, implementation, testing, and documentation
- Develop high-performance backend services primarily in Java, with supporting Python components
- Contribute to distributed, cloud-native systems deployed across AWS and GCP
- Ensure systems meet production standards for reliability, scalability, and performance
- Collaborate cross-functionally with Product, Quant, and Client teams to deliver institutional-grade solutions
Our take
So far, the increasing institutional interest in the value of crypto-assets has been stymied by a lack of scaled, efficient, and secure infrastructure that these institutions could use for trade. Talos addresses the problem of digital asset trading between institutions, helping them to securely sidestep these obstacles into a fresh market with potentially huge returns.
The company provides a range of end-to-end, highly configurable tools to populate and facilitate the institutional crypto-asset market from just one platform. Talos' approach is helping to lower the bar for wide-ranging adoption of cryptocurrency, supporting the full lifespan of digital assets trading. That said, because the company is developing an entirely new asset class market, progress is accelerated, and competition may have a chance to overtake.
Promising for Talos was the interest of prominent investors, including PayPal and Fidelity, during their Series A and B funding rounds. The funds were used to create an institutional-grade service that would help shape and spearhead this developing market. More recently, the company has formed several significant partnerships, including with BlackRock, and acquired D3X Systems, the integration of which will enable its clients to design, validate, implement, and manage highly customised portfolios.
