The Ethereum Basis has opened functions for the 2026 Internship Program: a paid, full-time alternative to work straight with groups advancing the Ethereum protocol and ecosystem.
Interns will be part of EF groups for 12 weeks over the summer season, contributing to lively R&D and ecosystem-oriented initiatives throughout a variety of focus areas. The internship is open to candidates worldwide and might be accomplished remotely or from EF’s places of work. A summer season meetup will deliver the cohort collectively to attach in individual.
The Objective
Ethereum continues to evolve; every improve, analysis initiative, and experiment depends upon individuals prepared to dive into complicated issues and assist construct what comes subsequent. The internship is designed to offer rising engineers and researchers a sensible path into that work. Interns contribute to actual initiatives beneath the steering of skilled mentors inside Ethereum’s open, collaborative surroundings.
Who Ought to Apply
This system is meant for college college students or latest graduates captivated with Ethereum, open-source contributions, and decentralized applied sciences. Excessive-signal candidates will have already got some understanding of Ethereum at a technical degree and need to deepen that understanding by means of utilized work. Candidates ought to be self-directed and cozy exploring unfamiliar methods.
Utility Course of
Purposes are open now by means of December 1, 2025. Shortlisted candidates will then be invited to interviews over the following two months, with last picks introduced by early February. The internship runs for about 12 weeks in the course of the summer season, with versatile begin and finish dates to match educational calendars.
2026 Internship Roles
Groups throughout the EF are in search of interns. Every function is related to an EF staff or initiative with lively initiatives. Candidates ought to evaluate the complete listings on the EF job board for particulars on scope, most well-liked expertise, and instance duties.
Cryptography Analysis
The EF cryptography analysis staff designs and analyzes cryptographic primitives crucial to Ethereum’s roadmap, advises protocol and shopper groups on safety selections, and publishes peer-reviewed outcomes that maintain Ethereum on the bleeding fringe of cryptography analysis.
👉 Apply
DevOps
EthPandaOps helps guarantee a properly examined, coordinated, and protected fork on Ethereum. They obtain these targets by way of customized tooling, deployment scripts, and information assortment pipelines. Moreover, EthPandaOps goals to empower the neighborhood to repurpose instruments for their very own wants, lowering general effort whereas guaranteeing minimal requirements.
👉 Apply
Funding Coordination
The Strategic Funding Coordination staff helps EF grantees and different important public items initiatives safe co-funding from ecosystem grants, authorities applications, philanthropic organizations, and choose industrial companions.
👉 Apply
Geth (Go-Ethereum)
The go-ethereum staff builds Geth, an Ethereum execution-layer shopper written in Go. Inside the EF, they do analysis and improvement of the Ethereum protocol. As core builders, they form the protocol and choose exterior contributions.
👉 Apply
P2P Networking
The P2P Networking staff addresses a confirmed bottleneck in Ethereum as we speak: the networking layer. They work on two fronts: bettering the present stack to ship on Ethereum’s brief and medium-term ambitions whereas conducting radical, first-principles pondering to revamp the networking layer from scratch for long-term scalability and development. They collaborate intently with shopper implementers, researchers, and libp2p maintainers throughout the ecosystem.
👉 Apply
Protocol Consensus
The Protocol Consensus staff’s mission is to bridge the hole between the ensures offered by Ethereum’s consensus protocol as we speak and people essential to totally assist the community’s long-term values and targets. To maneuver towards this aim, they give attention to actions resembling protocol design, theoretical evaluation, specification writing, academia engagement and collaboration with the broader ecosystem to make sure that concepts might be translated into follow.
👉 Apply
Protocol Prototyping
The Protocol Prototyping staff builds end-to-end implementations of latest concepts for Ethereum’s core protocol. By turning ideas into working prototypes, the staff explores how potential upgrades behave in follow, serving to the neighborhood transfer past concept and hypothesis. Their work assessments assumptions, quantifies trade-offs, and uncovers dangers that will not be obvious from analysis alone.
👉 Apply
Protocol Safety
The Protocol Safety Analysis staff safeguards Ethereum’s integrity. By way of coordination, meticulous code critiques, creating superior tooling, and real-world simulations, the staff focuses on securing the community and its crucial elements. Their hands-on method consists of managing the bug bounty program, constantly monitoring the community, and collaborating with shopper groups.
👉 Apply
Protocol Snarkification
The Protocol Snarkification is devoted to snarkifying the Ethereum protocol, alongside the Cryptography and zkEVM groups. Particularly, the staff has a give attention to formal verification utilized to cryptographic protocols and their implementations.
👉 Apply
Protocol Specs & Testing
The Specs and Testing for the Ethereum Execution Layer (STEEL) staff consists primarily of two initiatives: Ethereum Execution Layer Specification (EELS) and Ethereum Execution Specification Assessments (EEST).
- The EELS challenge is answerable for the primary Ethereum protocol reference specification written in Python, which goals in the direction of changing the yellow-paper specification and being a vital help to the EIP course of in an effort to present a prototyping framework for brand spanking new updates.
- The EEST challenge is answerable for the Ethereum protocol reference assessments, utilized by all shoppers to detect consensus points throughout new hard-fork implementations and regressions.
The staff additionally helps testing efforts for the consensus-specs, takes care of sustaining and bettering the tooling, frameworks, documentation and steering required to facilitate the shopper builders with the consumption of the assessments.
👉 Apply
Sturdy Incentives Group
The Sturdy Incentives Group (RIG) is a analysis staff devoted to the research of the Ethereum protocol by means of the lens of mechanism design. Their work maps all of the ways in which incentives straight or not directly have an effect on Ethereum members. The place doable, the staff proposes mechanisms to realize incentive compatibility and system optimality.
👉 Apply
zkEVM
Bringing zkEVMs to the Ethereum layer 1 is a multi-faceted effort. The zkEVM staff’s work is organized into three core workstreams; real-time proving, shopper and protocol integration, and financial incentives and safety.
👉 Apply
A Path Into the Protocol Layer
The EF Internship Program gives an entry level into protocol-level work. It’s a possibility to contribute meaningfully whereas gaining expertise, mentorship, and context for a way Ethereum is maintained and superior.
