The Ethereum Basis has opened functions for the 2026 Internship Program: a paid, full-time alternative to work instantly with groups advancing the Ethereum protocol and ecosystem.
Interns will be a part of EF groups for 12 weeks over the summer time, contributing to energetic R&D and ecosystem-oriented tasks throughout a variety of focus areas. The internship is open to candidates worldwide and may be accomplished remotely or from EF’s workplaces. A summer time meetup will deliver the cohort collectively to attach in individual.
The Purpose
Ethereum continues to evolve; every improve, analysis initiative, and experiment is dependent upon folks keen 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 tasks beneath the steering of skilled mentors inside Ethereum’s open, collaborative atmosphere.
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 stage and wish to deepen that understanding via utilized work. Candidates ought to be self-directed and comfy exploring unfamiliar methods.
Software Course of
Functions are open now via December 1, 2025. Shortlisted candidates will then be invited to interviews over the following two months, with remaining picks introduced by early February. The internship runs for roughly 12 weeks throughout the summer time, with versatile begin and finish dates to match tutorial calendars.
2026 Internship Roles
Groups throughout the EF are searching for interns. Every position is related to an EF staff or initiative with energetic tasks. Candidates ought to overview the total listings on the EF job board for particulars on scope, most popular abilities, and instance duties.
Cryptography Analysis
The EF cryptography analysis staff designs and analyzes cryptographic primitives important 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 effectively examined, coordinated, and secure fork on Ethereum. They obtain these objectives through customized tooling, deployment scripts, and knowledge assortment pipelines. Moreover, EthPandaOps goals to empower the neighborhood to repurpose instruments for their very own wants, lowering general effort whereas making certain minimal requirements.
👉 Apply
Funding Coordination
The Strategic Funding Coordination staff helps EF grantees and different important public items tasks safe co-funding from ecosystem grants, authorities applications, philanthropic organizations, and choose business 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 immediately: the networking layer. They work on two fronts: bettering the present stack to ship on Ethereum’s quick and medium-term ambitions whereas conducting radical, first-principles considering 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 immediately and people needed to totally help the community’s long-term values and aims. To maneuver towards this objective, they give attention to actions reminiscent of protocol design, theoretical evaluation, specification writing, academia engagement and collaboration with the broader ecosystem to make sure that concepts may be translated into apply.
👉 Apply
Protocol Prototyping
The Protocol Prototyping staff builds end-to-end implementations of recent concepts for Ethereum’s core protocol. By turning ideas into working prototypes, the staff explores how potential upgrades behave in apply, serving to the neighborhood transfer past principle and hypothesis. Their work exams assumptions, quantifies trade-offs, and uncovers dangers that is probably not obvious from analysis alone.
👉 Apply
Protocol Safety
The Protocol Safety Analysis staff safeguards Ethereum’s integrity. By means of coordination, meticulous code evaluations, creating superior tooling, and real-world simulations, the staff focuses on securing the community and its important elements. Their hands-on method contains managing the bug bounty program, repeatedly 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 tasks: Ethereum Execution Layer Specification (EELS) and Ethereum Execution Specification Checks (EEST).
- The EELS venture is chargeable for the primary Ethereum protocol reference specification written in Python, which goals in direction of changing the yellow-paper specification and being a vital help to the EIP course of as a way to present a prototyping framework for brand spanking new updates.
- The EEST venture is chargeable for the Ethereum protocol reference exams, 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 exams.
👉 Apply
Strong Incentives Group
The Strong Incentives Group (RIG) is a analysis staff devoted to the research of the Ethereum protocol via the lens of mechanism design. Their work maps all of the ways in which incentives instantly or not directly have an effect on Ethereum members. The place doable, the staff proposes mechanisms to attain incentive compatibility and system optimality.
👉 Apply
Stateless Consensus
Stateless Consensus builds superior prototypes and instruments with the first goal of ushering in a stateless Ethereum period, which can make Ethereum extra scalable, usable, and ubiquitous.
👉 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 affords an entry level into protocol-level work. It’s a chance to contribute meaningfully whereas gaining expertise, mentorship, and context for a way Ethereum is maintained and superior.
