Core Blockchain Developer information

What is a core blockchain developer?

Core Blockchain Developers are specialized software engineers responsible for designing, developing, and maintaining the foundational architecture of blockchain systems. They create and optimize the core protocols, consensus algorithms, and security mechanisms that enable decentralized networks to operate effectively. Unlike application developers who build on top of blockchain platforms, core developers work directly on the blockchain’s underlying infrastructure. Their work ensures the network’s efficiency, scalability, and security, making them essential for the evolution and stability of blockchain technology.

What are the key skills and qualifications needed to thrive as a core blockchain developer?

To thrive as a Core Blockchain Developer, you need deep expertise in computer science, cryptography, and distributed systems, often supported by a degree in a related field and experience with blockchain protocols. Proficiency with programming languages such as C++, Go, or Rust, as well as familiarity with blockchain frameworks and tools like Ethereum and Hyperledger, is typically required. Strong problem-solving skills, attention to detail, and effective communication are crucial soft skills for collaborating with other developers and addressing complex technical challenges. These skills ensure secure, efficient, and scalable blockchain infrastructure that meets the needs of users and organizations.

What are some common challenges core blockchain developers face when working on protocol-level changes?

Core Blockchain Developers often encounter challenges such as ensuring backward compatibility during protocol upgrades, maintaining network security, and achieving consensus among distributed stakeholders. Testing and deploying changes require rigorous peer review and extensive collaboration with other developers and the broader community to prevent disruptions. Additionally, developers must stay updated with evolving cryptographic standards and scalability solutions to keep the blockchain secure and efficient.

What is the difference between Core Blockchain Developer vs Blockchain Software Engineer?

AspectCore Blockchain DeveloperBlockchain Software Engineer
Primary FocusDeveloping and maintaining blockchain protocols, consensus algorithms, and core infrastructureBuilding blockchain applications, smart contracts, and user-facing solutions
Required SkillsDeep understanding of blockchain architecture, cryptography, consensus mechanismsProficiency in programming languages, smart contract development, API integration
Work EnvironmentTypically in blockchain development teams, R&D, or core protocol projectsIn software development teams, creating decentralized apps and tools
Industry UsageUsed by blockchain protocol projects, core infrastructure providersUsed by dApp developers, fintech companies, and blockchain startups

While both roles require blockchain knowledge, Core Blockchain Developers focus on building and optimizing the underlying blockchain protocols, whereas Blockchain Software Engineers develop applications and smart contracts on top of existing blockchain platforms.

Job description

"SZNS Solutions (pronounced "seasons") is a technology consulting company and Google Cloud Partner based in Reston VA. We specialize in delivering agentic AI and cloud computing solutions. Founded by ex-Googlers with engineers from Google, Amazon, and Capital One, SZNS differentiates itself particularly in AI, data engineering, blockchain, and cloud-native software application development.”

Role Summary

We’re seeking a Forward Deployed Software Engineer (FDE) that operates at the intersection of product engineering, sales engineering, and technical consulting. As a builder, translator, and change agent, you will embed directly with strategic enterprise and government partners to solve their most complex operational bottlenecks. We are not a traditional consulting firm; we are builders who believe that the best way to advise a customer is to show them working software.

Key Responsibilities

  • Rapidly Build and Deploy: Embed with customer teams to design, build, and deploy new workflows or applications from first sketch to real-world impact
  • Agentic Workflows: Design evaluation and feedback loops to verify AI performance and safety, ensuring reliable deployments. Perform threat modeling and evaluation to ensure robust guardrails and "Non-Human Identity" policies to ensure enterprise safety
  • Trusted Technical Advisor: Be the principal technical interface to client leadership and stakeholders for accelerating deals and long-term strategic partnerships
  • Client Enablement: As the resident expert, you’ll participate with client-side workshops, technical trainings, and hackathons
  • Always Improve: Extract field insights and translate them into reusable patterns, accelerators, and playbooks that strengthen the core SZNS platform for future customers

Requirements

Minimum Qualifications

  • Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience
  • Strong cloud experience (GCP, AWS, Azure)
  • Strong full-stack proficiency, particularly in Python, TypeScript, Go, Rust, or Java
  • Demonstrated experience building and shipping production-quality code in ambiguous, fast-paced environments
  • Experience deploying Agentic workflows (e.g., ADK, Agents SDK) and agent orchestration
  • Experience building evaluation frameworks for AI workflows and systems
  • Familiarity and efficient use of AI-enabled tools (e.g., Gemini Code Assist, Claude Code, or Codex)
  • Deep customer empathy, low ego, and exceptional communication skills to bridge the gap between complex engineering systems and business leaders
  • Experience with containerized environments (Kubernetes/GKE)
  • Active Google Cloud certifications, or willingness to obtain within one month of joining
  • Obsession for impact in highly ambiguous environments and favors rapid action over perfect clarity
  • US Citizen
Preferred Qualifications
  • 5+ years of professional experience in software engineering, cloud architecture, and deployments
  • Experience in a software consulting or professional services capacity for strategic accounts
  • Experience with multi-cloud or hybrid cloud environments
  • Prior customer-facing or technical pre-sales experience
  • Prior experience with containerized environments (Kubernetes/GKE)
  • Familiarity with regulatory compliance frameworks (FedRAMP, HIPAA, etc.) and security strategies
  • A proven track record of mentorship and raising the technical bar for engineering teams

Benefits

    • Competitive salary and benefits package
    • Hybrid work environment (MWF in-person in our Reston office)
    • A collaborative and innovative work environment
    • Continuous learning and development opportunities
