Substrate Developer information

What is a Substrate developer?

Substrate Developers are software engineers who specialize in building blockchain applications and networks using the Substrate framework. Substrate is a modular, open-source toolkit developed by Parity Technologies that allows for the creation of customized blockchains, often used for projects built on the Polkadot ecosystem. These developers work with languages like Rust to design, implement, and maintain blockchain protocols and features, leveraging Substrate’s flexibility to meet specific project requirements.

What are the key skills and qualifications needed to thrive as a Substrate developer, and why are they important?

To thrive as a Substrate Developer, you need strong proficiency in Rust programming, blockchain fundamentals, and a solid understanding of Substrate's framework, often demonstrated by experience with open-source contributions. Familiarity with tools like Polkadot JS, Substrate Node Template, and knowledge of relevant cryptographic protocols or certifications in blockchain technologies is valuable. Strong problem-solving abilities, collaboration, and adaptability to rapidly evolving tech are crucial soft skills for this role. These competencies are essential for building secure, scalable, and innovative blockchain solutions in the dynamic Web3 ecosystem.

What are some common challenges faced by Substrate developers when building blockchain solutions?

Substrate Developers often encounter challenges such as understanding the complex modular architecture of Substrate, ensuring security in custom runtime development, and optimizing performance for scalability. Debugging runtime logic and integrating with various blockchain tools can also be demanding due to the rapidly evolving ecosystem. Collaboration with other developers, auditors, and community members is essential to overcome these challenges and deliver robust blockchain applications.

What is the difference between Substrate Developer vs Blockchain Developer?

AspectSubstrate DeveloperBlockchain Developer
CredentialsProficiency in Rust, blockchain frameworks, and Substrate SDKKnowledge of blockchain concepts, smart contracts, and various blockchain platforms
Work EnvironmentFocus on building custom blockchain frameworks using SubstrateDeveloping decentralized applications, smart contracts, or blockchain protocols
Industry UsagePrimarily in blockchain infrastructure and protocol developmentBroader, including DApps, smart contracts, and blockchain solutions

Substrate Developers specialize in creating blockchain frameworks using the Substrate SDK, focusing on blockchain infrastructure. Blockchain Developers have a broader role, working on smart contracts, DApps, and various blockchain platforms. While both roles require blockchain knowledge, Substrate Developers are more technical and framework-oriented, whereas Blockchain Developers work across multiple blockchain applications.

Job description

ABOUT LUMILENS

At Lumilens we are building the critical photonics infrastructure that powers tomorrow’s AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.

We’re a well‑funded startup backed by Mayfield and led by veterans who’ve built and scaled some of the most transformative technologies in the industry. This isn’t incremental innovation, it’s a ground‑floor opportunity to rethink the optical layer from the silicon up. You’ll work alongside a team of world‑class engineers solving some of the hardest challenges in optics, systems, and scale. Every line of code, every design decision, every breakthrough you help deliver will shape the infrastructure of tomorrow.

If you're looking for mission, momentum, and the chance to make an outsized impact jump on the rocket ship. We’re just getting started.

Position Overview

We are seeking a hands‑on Component Process Engineer to serve as the primary substrate engineering interface between Lumilens’ hardware design teams, package manufacturing teams and worldwide substrate suppliers.

This role focuses on FR4 substrate or PCB from new technology development, process development to qualification of the suppliers. The candidate must have solid hands‑on experience in FR4 substrate/PCB product development, very familiar with mSAP/HDI/Any_Layer manufacturing process. Engage with substrate/PCB design team during early development phase to provide DFM based on different PCB suppliers’ manufacturability.

This position is ideal for an engineer who combines deep Material/Chemistry/Mechanical/Electrical knowledge with a passion for manufacturing process excellence, supplier development, and cross‑functional execution at a global scale.

Key Responsibilities
  • Identify, develop and qualify FR4/PCB substrate suppliers worldwide.
  • Lead DFM/DFT/DFR of PCB substrates, risk analysis and mitigation plan with suppliers.
  • Lead FR4/PCB quality control, failure analysis and reliability tests.
  • Engage with packaging production teams during the process development from SMT, die attach, wire bond, active alignment and testing.
Required qualifications
  • B.S. or M.S. in Material, Chemistry or Mechanical Engineering.
  • 8+ years of working experience in FR4 substrate or PCB development or manufacturing, with in‑depth knowledge in mSAP process, Any‑Layer HDI process, for high‑speed optical transceiver applications. Must be very familiar with all the equipment, typical materials and the typical process capabilities.
  • Familiar with PCB layout tools such as Cadence, mechanical design tools such as Solidworks, statistical tools such as JMP.
  • Working knowledge of PCB test methodologies.
  • Familiar with FMEA, Control Plan, SPC, 8D, etc.
  • Fluency in English to communicate with English speaking stakeholders.
  • 30~50% travel in Asian countries.
Preferred qualifications
  • M.S. in Electrical or Manufacturing Engineering
  • Experience with optical transceiver manufacturing process such as SMT, die attach, wire bonding and active alignment.
  • Six Sigma, Statistical Analysis skills.
What We Offer
  • Competitive salary and meaningful equity in a high‑growth company
  • Comprehensive health, dental, and vision coverage
