What are some common challenges smart contract engineers face when ensuring contract security?

Smart Contract Engineers often encounter challenges related to identifying and mitigating vulnerabilities such as reentrancy attacks, integer overflows, and unauthorized access. Since smart contracts are immutable once deployed, engineers must rigorously test and audit their code to prevent costly errors or exploits. Collaborating with auditors, using established security frameworks, and staying updated on the latest security threats are essential practices to maintain robust and secure smart contracts.

What is the difference between Smart Contract Engineer vs Blockchain Developer?

AspectSmart Contract EngineerBlockchain Developer
CredentialsKnowledge of blockchain platforms, Solidity, cryptographyBroader programming skills, blockchain fundamentals
Work EnvironmentFocus on smart contract coding, testing, deploymentDeveloping blockchain applications, protocols
Industry UsagePrimarily in DeFi, NFT, and dApp projectsWide range including wallets, exchanges, dApps
Search IntentComparing smart contract roles, coding specificsBroader blockchain development roles

While both roles work within the blockchain industry, a Smart Contract Engineer specializes in designing, coding, and deploying smart contracts on blockchain platforms. A Blockchain Developer has a broader scope, including developing entire blockchain applications and protocols. The Smart Contract Engineer's focus is more technical and contract-specific, whereas the Blockchain Developer's role encompasses a wider range of blockchain solutions.

What is a smart contract engineer?

A Smart Contract Engineer is a software developer who specializes in designing, developing, testing, and deploying smart contracts on blockchain platforms such as Ethereum. These professionals write code—often in languages like Solidity or Vyper—that runs autonomously on the blockchain and governs transactions or agreements without the need for intermediaries. They also focus on security, auditing, and optimizing smart contract performance to prevent vulnerabilities. Smart Contract Engineers typically collaborate with blockchain architects, front-end developers, and project managers to build decentralized applications (dApps).

What are the key skills and qualifications needed to thrive as a smart contract engineer?

To thrive as a Smart Contract Engineer, you need strong proficiency in blockchain fundamentals, programming languages like Solidity or Vyper, and a solid understanding of cryptographic principles, usually backed by a degree in computer science or related experience. Familiarity with blockchain development frameworks (e.g., Truffle, Hardhat), version control (Git), and security auditing tools is essential. Attention to detail, problem-solving abilities, and effective communication are crucial soft skills for this role. These skills ensure the development of secure, efficient, and reliable smart contracts that underpin decentralized applications and financial systems.

Job description

Job Summary:
Metropolis is creating artificial intelligence to make the real world responsive, pioneering the Recognition Economy. They are seeking a Senior AI Engineer to design and ship AI-powered tools and automation pipelines, transforming manual processes into AI-first workflows.
Responsibilities:
• Design, build, and ship AI-powered automation tools and internal applications that transform manual business processes into AI-first workflows
• Architect and maintain LLM-based systems, including prompt pipelines, agentic workflows, tool-calling integrations, and retrieval-augmented generation (RAG) setups
• Build and maintain data pipelines that connect source systems (Snowflake, internal APIs, SaaS tools) to AI workflows, ensuring data quality and reliability
• Partner with Process Analysts to understand how business functions work today, translate requirements into engineering specifications, and iterate based on real user feedback
• Own production reliability for the systems you build — monitoring, alerting, and iterating on AI outputs to maintain quality over time
• Evaluate and integrate emerging AI tooling (models, frameworks, APIs) to ensure Metropolis is always leveraging the best available capabilities
• Contribute to internal standards for AI development: prompt management, evaluation frameworks, model selection, and system architecture
Qualifications:
Required:
• 6+ years of software engineering experience, with 2+ years of hands-on experience designing, building, and deploying LLM-based or AI-powered applications in production
• Strong Python skills — you write clean, maintainable code and are comfortable building APIs, data pipelines, and backend services
• Practical experience with LLM APIs (OpenAI, Anthropic, or similar), prompt engineering, and agentic patterns (function calling, multi-step reasoning, tool use)
• Familiarity with data engineering fundamentals: SQL, data transformation, working with cloud data warehouses (Snowflake preferred)
• Experience with workflow orchestration tools (e.g., Airflow, Prefect, or similar) and cloud infrastructure (AWS preferred)
• A strong instinct for product quality — you care about whether the tools you build are actually useful, not just technically functional
• Ability to work autonomously in a fast-moving environment, manage competing priorities, and ship iteratively rather than waiting for perfection
Preferred:
• Experience with vector databases, embeddings, or semantic search is a plus
Company:
Take the uncertainty out of smart contract deployments. Build confidence from the command line. Founded in , the company is headquartered in , , with a team of 11-50 employees. The company is currently Early Stage.
