C++, Golang, C#, JavaScript, Solidity, Python, Ruby, and Java are considered some of the most popular programming languages for blockchain development. It is also important for a blockchain developer to have familiarity with web development programming languages such as HTML and CSS as many roles are focused on building a web app or mobile application.


When sourcing candidates, look for a blockchain developer with a strong understanding of blockchain architecture key functions including cryptography and security principles. Experience with concepts including cryptography hashing, transactions, and wallets are key functions of cryptography.

Smart Contracts

Smart contracts are another important part of a blockchain developer's experience to scan for when hiring. Smart contract functionality in systems plays an important role in the development of blockchain companies and business applications. Network-specific languages include Solidity, Viper, Chaincode, Golang, and others.

Learning on the Go

With the ever-changing landscape of web3 and blockchain development, look for a developer willing to learn on the go and be adaptable to change. A good hire will continuously learn and showcase flexibility to adapt to new changes in the industry.

Blockchain developers at startups

Attract top Blockchain developers on Wellfound

Startups can post a job for Blockchain developers and review candidates on Wellfound Talent for free. When posting a job for Blockchain engineers, learn how to write a job posting to attract the right talent.

  • Add a title, location, skills, and more. These are the most relevant fields to help your job post show up in a candidate’s job search. Include “Blockchain“ in the job description to filter for engineers with blockchain experience.
  • Add details for the company, role, and ideal candidate. All Wellfound job postings have a free-form section where you can explain in detail about the company, role, and/or what you’re hiring for. A few suggestions to include:
  1. Startup name
  2. Title
  3. Main role responsibilities
  4. Programming languages required for the role (i.e. object-oriented programming)
  5. Qualifications for Blockchain developers (i.e. knowledge of cryptography smart contracts)
  6. Preferred or ideal soft skills for Blockchain developers (i.e. willing to learn on the go)
  • Optimize your company profile. Typically, a candidate will first click on a company profile to learn more when evaluating a job post. Confirm your startup profile is up-to-date and with all sections filled out — candidates rely on this to inform their job search!

Source Blockchain developers on Wellfound with ease

On Wellfound, you can also discover candidates by sourcing — instead of posting a job and waiting for candidates to apply, you can find potential candidates and pitch your opportunity directly to them.

The vast majority of candidates on Wellfound are specifically interested in joining a startup. With Source, our team provides key information including which candidates are actively looking for a job, what skills they have, their ideal salary, and more.

When sourcing for Blockchain developer’s on Wellfound, we suggest beginning with the following key points:

  • Role and Title: Begin your search by filtering for those with a current or previous “Blockchain engineer” title. Depending on your needs, you could also include “blockchain developer” or web3 developer“ to widen your search to help filter candidates with matching titles.
  • Skills Required: Add specific languages and technologies you’re looking for experience in. For Blockchain developers, some programming languages include C++, Java, and Solidity. Your search will depend on what technologies your codebase is in.
  • Location Preferences: Filter for candidates on remote preferences or in a specific location (whether they’re only open to remote, only open to in-office, or both). If you’re looking for remote Blockchain developers, you can search by remote candidates in specific time zones.
  • Level of Experience: Clarify the level of experience in the Blockchain and web3 industry you’re looking for. If you’re open to multiple levels for Blockchain developer positions, you can always leave this filter open to allow a wider range of candidates to show up.

With Sourcing, a list appears based on whether they are passive Blockchain candidates (open to interviews, but not actively looking), active Blockchain candidates (actively looking and ready to interview), or curated Blockchain candidates (ready to interview and vetted by our team).
