Seal Labs Overview

Seal Labs is a financial technology firm pioneering next-generation infrastructure for modern financial systems. We specialize in advanced protocol architecture, real-time risk management engines, and user-centric products designed for institutional performance and security.

As part of our strategic expansion, we're building systems that merge the efficiency and composability of digital assets (DA) and decentralized finance (DeFi) with the rigor and stability of traditional finance (TradFi). Our work redefines how risk, capital optimization, and systemic integrity are managed in a digital-first financial world.

Position Overview

We're developing state-of-the-art institutional infrastructure that modernizes how financial systems operate, enhancing TradFi's robustness through the connectivity, automation, and composability of digital assets.

We're seeking a Senior Backend Engineer with deep experience in high-performance financial systems to architect and implement our core backend from the ground up. You'll help build systems that are secure, auditable, and optimized for scale, enabling a more unified and intelligent financial ecosystem.

You don't need prior blockchain or Rust experience; what matters most is a solid foundation in system design, a rigorous understanding of transactional and capital flow logic, and the ability to build mission-critical systems.

Team & Collaboration

• You'll join a lean product team of 10 engineers (and growing) and product owners, working in a scrum based environment

• Report directly to the Tech Lead/CTO with close collaboration with Product Owners

• Work with cross-functional stakeholders including protocol designers and integration partners

• Core team operates in GMT+7, but we accommodate other timezones with 3-4 hour overlap

Key Responsibilities

• Design and implement core backend services for the clearing engine, margin system, and risk modules.

• Translate financial workflows (settlement, reconciliation, liquidity, PnL, etc.) into deterministic, auditable logic.

• Optimize system performance for low-latency and high-throughput operations.

• Influence product roadmap based on technical feasibility and system constraints

• Collaborate with product and protocol teams to design APIs for external integrations and partner protocols.

• Maintain strong observability, testing, and security standards (Grafana, Prometheus, distributed tracing).

• Participate in architectural reviews and contribute to long-term scalability strategies.

• Gradually transition core modules into Rust-based smart contract logic

Required Qualifications

• 5+ years of experience in backend engineering (Java, Go, C++, or Rust).

• Strong understanding of financial or fintech systems — banking, payment, trading, or clearing platforms.

• Solid grasp of transactional consistency, event-driven architecture, and data integrity.

• Experience with microservices, API gateway design, and distributed caching / queue systems (Kafka, Redis, RabbitMQ, etc.).

• Familiarity with system observability and debugging (Grafana, ELK, Prometheus).

• Strong problem-solving mindset and ability to translate abstract financial logic into clean, modular code.

Nice to have

• Exposure to Rust.

• Experience with high-frequency trading, risk management, or clearing systems.

• Familiarity with blockchain fundamentals (wallets, smart contracts, or on-chain data).

What We Offer

• Competitive salary based on your capabilities with 2 annual performance reviews

• Opportunity to work directly with DeFi and fintech veterans on next-generation financial infrastructure.

• Early-stage opportunity: As an early technical hire, you'll have first-mover advantage for Staff Engineer/Architect roles as we scale

• Collaborative learning environment with knowledge-sharing on Rust, DeFi architecture, and on-chain systems (we learn from your fintech expertise, you learn our blockchain stack)

• Full remote working environment with high respect for personal time management

• Project-based token bonus
