Lead Blockchain Architect
Blockchain Architect Layer 1 / Protocol Design
Luxium AGLocation: Zug, Switzerland / Remote
Engagement: Initial contract\-based architecture phase, with potential for long\-term role
About Luxium
Luxium AG is a Swiss based company building a next\-generation blockchain ecosystem with a strong focus on protocol level design, transparent monetary logic, and long\-term infrastructure development.
We are currently looking for an experienced Blockchain Architect to help define the overall technical foundation of the project during an initial architecture and planning phase. This role is intended to begin as a short term paid engagement focused on shaping the full blockchain ecosystem, with the possibility of transitioning into a permanent senior position for the right person.
Role Overview
This is a senior role for someone who can think beyond application\-level blockchain development and help design the architecture of a new Layer 1 ecosystem from the ground up.
In the initial phase, the main objective will be to work closely with the founders and technical team to define the core architecture, evaluate technical directions, identify major trade\-offs, and help shape the broader blockchain roadmap.
If there is a strong fit on both sides, the role can evolve into a long\-term leadership position within the team.
Initial Scope of Work
During the first phase, you will help us define and structure the following:
overall Layer 1 blockchain architecture
consensus and validation approach
node structure and system design
transaction flow and fee logic
ecosystem architecture and technical roadmap
scalability, security, and decentralization trade\-offs
recommended implementation stages
technical requirements for future team expansion
Responsibilities
Design the core architecture of a new blockchain ecosystem
Analyze and recommend suitable protocol\-level approaches
Define system logic, validation structure, and network design
Translate high\-level ideas into practical technical architecture
Prepare architecture documentation and technical recommendations
Work closely with founders and developers on roadmap definition
Help identify risks, bottlenecks, and technical priorities
Support future technical hiring decisions if needed
Requirements
Proven experience in blockchain architecture, protocol engineering, or distributed systems design
Strong understanding of Layer 1 blockchain design principles
Deep understanding of consensus models, transaction validation, and network architecture
Strong background in distributed systems and system design
Good understanding of cryptographic fundamentals relevant to blockchain systems
Ability to produce clear technical documentation and architecture plans
Strong communication skills and practical thinking
Ability to challenge assumptions and propose better technical solutions
Strong Plus
Previous work on Layer 1 protocols or core blockchain infrastructure
Experience with Rust, Go, C\+\+, or similar backend/system languages
Experience designing scalable and secure distributed systems
Open\-source blockchain contribution history
Experience working with international remote teams
Experience in early\-stage architecture planning
Engagement Structure
This role is designed to begin with an initial paid architecture phase. The purpose of this first stage is to jointly define the technical direction, full blockchain roadmap, and ecosystem structure before moving into full\-scale execution.
For the right candidate, this can develop into a long\-term senior role within Luxium AG.
We are open to:
short\-term contract
part\-time senior engagement
project\-based architecture engagement
transition into permanent role after initial phase
Compensation
Compensation depends on experience and scope of involvement.
Indicative range for the initial engagement:
contract\-based compensation to be agreed based on scope and seniority
long\-term role can be discussed after the initial phase
For candidates moving into a full\-time long\-term role, compensation may include:
competitive salary
performance\-based upside
token or equity participation, depending on structure
Why Join
Opportunity to shape a blockchain ecosystem from the ground up
High\-level architecture influence from the earliest stage
Direct collaboration with founders
Real opportunity to grow into a long\-term core leadership role
Swiss\-based company with ambitious long\-term vision
Flexible initial engagement structure
