Lead Engineer

The Firm Teesta Investment is a proprietary high-frequency trading and market-making firm focused on global digital asset markets. We build technology that enables us to compete in one of the most demanding engineering environments, where performance, reliability, and precision directly influence trading outcomes. Unlike traditional software systems, trading infrastructure operates under extreme constraints. Market data arrives continuously, execution windows are measured in microseconds, and every layer of the technology stack can influence performance. Building successful trading systems requires thoughtful engineering across infrastructure, networking, distributed systems, operating systems, and low-latency software. As a young and ambitious firm, we are building our technology from the ground up. This creates an opportunity for exceptional engineers to shape the architecture, engineering culture, and technical direction of the company from its earliest stages.

The Team This role sits at the core of our engineering organisation and works directly with the founder, traders, and quantitative researchers. We are intentionally small, highly technical, and engineering-driven. Decisions are made through technical discussion and evidence rather than hierarchy. Engineers at Teesta are expected to think beyond individual components. We value people who understand how the entire platform fits together, take ownership of difficult technical problems, and are motivated by building systems that improve every day.

The Role Building infrastructure for high-frequency trading is fundamentally different from building conventional software. Every component of the platform-from market data ingestion and networking to execution engines, infrastructure, security, monitoring, and deployment-must work together with predictable performance under demanding market conditions. Small improvements in latency, reliability, or operational efficiency can have a significant impact. As Lead Engineer, you will be responsible for designing, building, and continuously evolving the technology that powers our trading business. This is not a role for someone who has specialised in a single part of the infrastructure stack. We are looking for an engineer who has built trading infrastructure end to end and understands how every layer contributes to overall system performance. You should be comfortable moving between architecture, infrastructure, networking, operating systems, execution, security, cloud platforms, and production operations.

Depending On Your Experience, Your Work May Include

• Designing and evolving the architecture of our low-latency trading platform.
• Building high-performance execution systems capable of processing market data and placing orders with minimal latency.
• Developing scalable infrastructure for market data ingestion, storage, simulation, and backtesting.
• Optimising Linux systems, networking, and infrastructure for predictable low-latency performance.
• Designing deployment, observability, monitoring, and operational tooling for production trading systems.
• Building secure infrastructure and implementing best practices across systems, cloud environments, and engineering workflows.
• Working closely with traders and quantitative researchers to translate research into robust production systems.
• Leading complex engineering projects from design through production deployment while maintaining high standards for reliability, performance, and code quality.
• Hiring, mentoring, and developing a high-performing engineering team while fostering a culture of technical excellence, ownership, and continuous improvement.
• Evaluating and adopting technologies that improve engineering productivity, operational efficiency, and platform reliability.

What We're Looking For We're looking for engineers who combine deep systems expertise with strong technical leadership.

You Should Have

• 6+ years of experience building high-performance software, preferably within high-frequency trading or another latency-sensitive environment.
• Demonstrated experience building trading infrastructure from first principles with end-to-end ownership across the technology stack.
• Hands-on experience across architecture, networking, market data systems, execution platforms, production infrastructure, deployment, observability, and security-not just one specialised area.
• Exceptional programming skills in C++ and/or Rust.
• Strong understanding of distributed systems, Linux internals, operating systems, networking, and systems architecture.
• A track record of designing reliable, scalable, and maintainable production systems.
• Proven experience leading engineering teams and delivering complex technical projects.
• Excellent analytical and problem-solving skills, with the ability to make sound architectural decisions under evolving requirements.
• A bias for ownership, simplicity, and engineering excellence. Experience in cryptocurrency markets is valuable but not essential. We value exceptional engineering fundamentals and the ability to learn new domains quickly.

Beneficial Experience The following experience would be advantageous:

• High-frequency trading or electronic market-making systems.
• Cryptocurrency exchanges and digital asset markets.
• Kernel bypass technologies such as DPDK.
• Network optimisation and low-level systems programming.
• Performance tuning and latency optimisation.
• Large-scale simulation and backtesting platforms.
• AWS and cloud infrastructure.
• Blockchain infrastructure.
• Building engineering organisations and technical leadership in fast-growing companies.

Why Join Teesta? Joining Teesta means helping build the foundation of a high-performance trading firm. You'll work directly with founder, traders, and researchers to solve technically demanding problems with immediate business impact. You'll have the opportunity to shape our architecture, influence engineering culture, hire exceptional people, and build systems that operate at the limits of speed and reliability. If you're motivated by difficult systems problems, enjoy building from first principles, and want ownership over an entire technology platform rather than a single component, we'd love to hear from you.

Benefits

• Comprehensive health insurance for you and your dependants.
• Relocation assistance.
• Fitness and wellness reimbursement.
• Sponsorship for higher education and professional development.
• Fully stocked office with meals, snacks, and beverages.
• A collaborative, engineering-first culture with high ownership and minimal bureaucracy.
