Engineering Organization & Culture

At Bullish, we are engineering the institutional standard for the digital asset industry. Our mission is to build a platform centered on security and compliance, requiring a commitment to technical excellence that extends beyond delivering code. As a global organization, we set a high bar for those driven to do their best work alongside experienced, deeply specialized peers.

Engineers here treat development as a craft and own the outcome from concept to deployment. Our teams bring structure to ambiguity and shape the frameworks that support a global organization. We refuse to compromise on quality and seek problem solvers who thrive on complex technical challenges with real market consequences.

The Team: BTH Engineering

The Bullish Treasury (BTH) Engineering team develops the foundational infrastructure that powers the secure management and rapid expansion of our digital asset ecosystem. As stewards of the firm's digital treasury, we ensure every transaction is meticulously safeguarded through rigorous custody protocols, advanced vault architectures, and strict authorization rules. Our engineers tackle complex on-chain challenges to build automated DeFi workflows, resilient privacy structures, and transparent, real-time financial intelligence dashboards. By solving intricate blockchain integration problems with cutting-edge tooling, we deliver the operational rigor required to navigate decentralized markets and provide total data integrity from institutional exchange accounts to comprehensive treasury analytics.

What You'll Do:

• Build Full-Stack Solutions: Design and develop critical internal applications using React, TypeScript, and Python.

• Automate DeFi Operations: Architect multi-chain asset deployments, expand CLI tooling, and engineer robust "incognito" wallet structures to scale operations and minimize manual intervention.

• Own Modern Cloud Infrastructure: Deploy and manage systems end-to-end on GCP and Kubernetes, driving automated CI/CD pipelines via GitHub Actions, while leveraging tools for Infrastructure-as-Code (Terraform, Config Connector).

• Drive AI-Powered Engineering: Heavily leverage AI tooling and coding agents to accelerate full-stack development.

• Elevate Engineering Standards: Raise the bar for the team through code reviews, automated testing, and technical mentorship.

• Proven delivery of fault-tolerant systems with rigorous testing, observability, and HA/DR practices.

• Strong communication skills, both written and verbal, with the ability to convey complex technical concepts to technical and non-technical stakeholders across global teams.

• An agile working style, with the initiative to see what's broken or missing and own the fix end to end rather than waiting for an assignment.

• A can-do attitude, with the ability to work independently and collaboratively in a fast-paced environment. 

• Familiarity with the Crypto industry, DeFi protocols and a high-level understanding of various yield generation opportunities.

• Ability to use Large Language Models (e.g., Claude, Gemini) to accelerate delivery without compromising engineering standards.
