Senior Fullstack Developer
at Fintech company looking for nodejs developer location remote

The tech stack looks like the below (expect this to change as we scale):
- Typescript for APIs (REST and GraphQL)
- Kafka, Spark, and data warehouses for ML pipelines (spark on python/scala)
- Solidity + hardhat for smart contracts (in the future, rust, go and move)
- AWS & Terraform
- Full nodes
You can expect to do some or all of the following:
- Read through protocols’ whitepapers and smart contracts to derive metrics and analyze risks
- Architect the backend for APIs, async jobs, and blockchain integration
- Build clean, concise APIs for customer integration, along with the documentation
- Setup, run and maintain full and archive nodes across different chains
- Integrate with multiple partners like exchanges and custody providers
- Fool-proof security across the stack - encryption, hashing, privacy, VPC, etc.
- Infrastructure as code - build terraform scripts and ensure easy replication of the infra across different regions
- Research the top DeFi protocols to uncover better insights for our customers and evaluate their risk profiles, security, and historical returns
- Manage production deployments, logging, and monitoring
We expect you to be fairly comfortable with working with both web3 and web2 stacks. We do not expect that you have web3 experience on day 1, but you should be willing to wear multiple hats, learn things quickly and move fast.
About you
- Generalist, a solid engineer who can learn things on your own and have an eye for clean, tested, and well-documented code
- We don’t look at the number of years of work experience as a criterion, but rather see what you have done in your life so far (side projects, open-source contributions, blogs, etc.). We don’t care about degrees, the institutions you went to, or the companies you worked for before. We are open to talking as long as you have good judgment, great clarity, align with our values and have a strong track record of thoughtful work
- Understand the fundamentals of building and integrating APIs and secure systems. Bonus if you know a bit about blockchains and protocols
- You can be strong on the backend, front-end, or can dabble everywhere. We want you to play to your strengths and will provide enough opportunities to learn and do things outside of your comfort zone
Pay and benefits We offer a solid, competitive package (including early-stage equity) that is location agnostic. We give you the flexibility to choose the split between cash and equity.
