Software Engineer, Full-Stack; Research and Development

Eigen Labs is building the infrastructure for a more trustworthy internet.

Today's digital world runs on trust-me promises: "Trust that this AI model is giving you unbiased results." "Trust that this platform isn't manipulating your feed." "Trust that this service will honor its commitments." These trust assumptions create massive friction and limit what's possible online.

Eigen Cloud changes this by making any digital service verifiable
. Built on our Eigen Layer protocol, which has attracted billions in economic security, Eigen Cloud lets developers build applications with mathematical trust guarantees instead of pinky promises.

For developers, this means the best of both worlds:
Use familiar cloud tools and programming environments while gaining blockchain-level verifiability. No need to rewrite your application in specialized blockchain languages or accept the limitations of smart contract environments.

For the world, this unlocks transformative applications:

• AI systems with economic accountability for their outputs

• Social platforms with verifiable, manipulation-resistant algorithms

• Prediction markets that can resolve on any real-world event

• Financial services with cryptographic transparency

• Any application where trust and correctness matter

We're moving beyond crypto's current focus on digital money to make all digital interactions more trustworthy. With the fastest-growing developer ecosystem in crypto and backing from top-tier investors, we're at the inflection point where verifiable computing goes mainstream.

Ready to build the trust layer for the internet? We're looking for builders who want to solve hard problems and create technology that makes the digital world fundamentally more reliable.

You will collaborate directly with R&D to convert ambiguous problem statements into production-ready software and high-fidelity demos. In a typical week, you will partner with Design to map user flows, translate ambiguity into testable milestones, implement services and UIs, and instrument features (analytics, logging, tracing) to inform iterations. You will participate in customer conversations (e.g., AI research labs, gaming studios, fintech firms), distill requirements into clear product primitives, and own outcomes end to end—plan, build, launch, measure, refine.

We value product judgment and execution velocity: small, reviewable PRs; frequent, reliable releases; attention to UX details; and concise, well-structured documentation—paired with sound judgment to select the simplest tool that meets the need. You will also contribute reusable templates and internal tooling to accelerate subsequent prototypes. If you’re looking to collaborate with a talented team of engineers, driving innovation and inventing groundbreaking technologies, we look forward to hearing from you!

This is a full-time onsite position are our office in Seattle.

• Own features end-to-end: from design document to prototype.

• Build polished consumer-grade UI/UX (fast, intuitive, minimal surprises).

• Ship full-stack product surfaces (e.g., Next.js/React on the front; Type Script/Node, Go, or Python on the back).

• Build games

• Stand up and manage infra:
  Docker, basic cloud, databases, queues, and observability.

• Add instrumentation (analytics, logging), run experiments, and measure outcomes.

• Collaborate tightly with design, product, research, and partnerships.

• Maintain quality with code reviews, testing, and post-mortems.

• Full-stack fluency:
  Comfortable building in React/Next.js (or similar) and at least one backend runtime (Type Script/Node, Go, or Python), with experience designing APIs, modeling data, and working with real-time systems.

• Infra pragmatism:
  You can containerize with Docker, set up basic cloud (AWS/GCP/Vercel/Cloudflare), wire up CI/CD, and add observability (logs, traces, dashboards).

• Learning velocity:
  You pick up new frameworks, APIs, and tools quickly and use judgment to choose the simplest thing that ships.

• High agency & ownership:
  You decompose fuzzy problems into milestones, unblock yourself, and drive ideas from plan > build > launch > refine.

• Cross-functional collaboration:
  
  You work smoothly with…
