Contract Typescript Developer information

What are some typical challenges a contract Typescript developer might face when joining a new project?

As a Contract Typescript Developer, you may encounter challenges such as quickly adapting to an existing codebase, aligning with the team's development standards, and understanding project-specific workflows. Since contract roles often require rapid onboarding, you might need to familiarize yourself with various tools, libraries, and deployment processes in a short timeframe. Additionally, effective communication with remote or cross-functional teams is essential to ensure smooth collaboration and timely delivery of tasks.

What are the key skills and qualifications needed to thrive as a contract Typescript developer?

To thrive as a Contract Typescript Developer, you need a strong command of TypeScript, JavaScript, and web development fundamentals, often backed by a degree in computer science or relevant experience. Familiarity with frameworks like React or Angular, version control (Git), and experience with build tools and CI/CD systems are typically required. Excellent problem-solving, communication, and time management skills help developers stand out, especially in remote or fast-paced contract environments. These abilities ensure high-quality, maintainable code and seamless collaboration with diverse teams, which is vital for delivering successful projects on time.

What is a contract Typescript developer?

A Contract Typescript Developer is a software professional who specializes in using the TypeScript programming language to build and maintain web and software applications on a contractual basis. Unlike full-time employees, contract developers are typically hired for specific projects or timeframes, providing flexibility for both the developer and the employer. TypeScript is a superset of JavaScript that adds static typing, which helps in catching errors early and improving code quality. These developers often work remotely or on-site, collaborating with teams to deliver high-quality code solutions. Their expertise is highly sought after for projects requiring scalable, maintainable, and robust applications.

Job description


Note: Fidelity will not provide immigration sponsorship for this position.
The Role
We are seeking a highly skilled and technically driven individual with deep expertise in blockchain engineering to join Fidelity Digital Asset Management. This role is ideal for a hands-on expert who thrives in architecting and deploying advanced blockchain solutions, smart contracts that support Research, Trading, Risk, and Operations. You will serve as a senior technical authority, driving innovation and ensuring the robustness of our digital asset infrastructure.
  • Architect and oversee the development of blockchain-based systems and smart contracts across EVM, Solana, and Cosmos SDK platforms.
  • Lead technical design and implementation of crypto infrastructure, including secure deployment pipelines, testing frameworks, and audit processes.
  • Conduct deep technical reviews and audits of smart contracts, ensuring security, scalability, and compliance with DeFi standards.
  • Evaluate and implement emerging technologies, protocols, and tooling to enhance Fidelity's digital asset capabilities.
  • Serve as a technical liaison across engineering, trading, and risk teams to ensure seamless integration of blockchain systems into core workflows.
  • Drive the design and implementation of tokenization frameworks, on-chain asset lifecycle management, and cross-chain interoperability solutions.
  • Lead evaluation and integration of DeFi protocols, staking infrastructure, liquidity solutions, and institutional-grade custody platforms.
  • Establish best practices for blockchain security, smart contract governance, protocol monitoring, threat detection, and incident response.

The Expertise and Skills You Bring
  • 4+ years of hands-on experience in blockchain engineering, smart contract development, or crypto infrastructure, with a strong track record of technical delivery.
  • Deep understanding of EVM/SVM architecture, token standards (ERC-20, ERC-721, SPL), and DeFi primitives.
  • Proficiency in multiple programming languages including Python, Solidity, and JavaScript/TypeScript.
  • Experience with smart contract frameworks and tools such as Hardhat & Foundary.
  • Proven ability to lead complex technical projects and mentor senior engineers in a collaborative, high-performance environment.
  • Hands-on experience with Solana development concepts including Anchor Framework, SPL token integrations, Program Derived Addresses (PDAs), and Cross-Program Invocations (CPIs).
  • Strong knowledge of DeFi ecosystems including AMMs, lending protocols, liquid staking, yield generation, oracle networks, and tokenization platforms.
  • Expertise in smart contract security reviews, threat modeling, protocol risk assessments, and secure software development practices for institutional digital asset products.

The Team
Fidelity Digital Asset Management [FDAM] is building an investment platform offering digital asset products and services designed to meet the growing needs of Fidelity's retail customers and intermediary and institutional clients. The tokenization team is a highly collaborative group leading technical projects across the FDAM organization to enable effective management of investment products and services. Project examples include integration of vendor infrastructure, constructing models or tools, building automation across technologies, and portfolio or business analytics. As a hands-on team lead you will be expected to understand the function needs to both meet the expected outcome and continue to drive innovation.
Fidelity's Onsite Working Model
Fidelity is transitioning to a full-time onsite working model through a phased rollout across regions and roles. Currently, some roles and locations require 100% onsite presence, while others require less. Onsite expectations are likely to evolve as the rollout continues. This transition does not apply to fully remote roles.
The base salary range for this position is $140,000-285,000 USD per year.
Placement in the range will vary based on job responsibilities and scope, geographic location, candidate's relevant experience, and other factors.
Base salary is only part of the total compensation package. Depending on the position and eligibility requirements, the offer package may also include bonus or other variable compensation.
We offer a wide range of benefits to meet your evolving needs and help you live your best life at work and at home. These benefits include comprehensive health care coverage and emotional well-being support, market-leading retirement, generous paid time off and parental leave, charitable giving employee match program, and educational assistance including student loan repayment, tuition reimbursement, and learning resources to develop your career. Note, the application window closes when the position is filled or unposted.
Please be advised that Fidelity's business is governed by the provisions of the Securities Exchange Act of 1934, the Investment Advisers Act of 1940, the Investment Company Act of 1940, ERISA, numerous state laws governing securities, investment and retirement-related financial activities and the rules and regulations of numerous self-regulatory organizations, including FINRA, among others.
