Senior Software Engineer - JTX

Our client is launching a next‑generation, on‑chain trading platform engineered to deliver institutional‑grade speed, execution quality, and market visibility directly to active traders. As an early engineering team member, you will drive a true 0‑to‑1 product effort, translating complex distributed systems and blockchain market mechanics into seamless, high‑performance workflows. If you want to build the foundational product layer on top of high‑throughput transactional infrastructure, this role offers direct, unconstrained impact.

Senior Software Engineer

• Architect and implement core components for a greenfield decentralized trading application from the ground up.
• Construct low‑latency, highly resilient backend services that interface directly with high‑throughput blockchain transaction streams.
• Take complete ownership of critical infrastructure paths, including smart order routing, trade execution engines, real‑time market data feeds, and portfolio position tracking.
• Enforce rigorous security standards across all layers, including secure transaction signing protocols, infrastructure deployment, and data protection.
• Partner with cross‑functional product and infrastructure units to rapidly deploy features and iterate based on live user data.
• Drive foundational architectural choices, establishing engineering standards for a growing technical team.

• 5+ years of professional software engineering experience, with a heavy emphasis on distributed systems architecture.
• Advanced systems programming capabilities, preferably using Rust, though deep expertise in C/C++ or Go is highly acceptable.
• Demonstrated track record of deploying and maintaining high‑availability, low‑latency production applications.
• Security‑centric development approach with an intuitive understanding of system vulnerability surfaces, cryptographic key management, and complex failure recovery modes.
• Ability to execute independently and make sound technical decisions within fast‑paced, fluid startup environments.

• Prior exposure to blockchain runtime environments, transaction life cycles, or decentralized trading infrastructure.
• Background in exchange engineering, order matching systems, or traditional high‑frequency trading (HFT) platforms.
• Experience developing core fintech backend architectures, including payment rails, institutional custody, or execution venues.
