Back End Developer Trainee

Senior Backend Developer

Job Overview: We are looking for a highly skilled and experienced Backend Developer who excels in building robust, scalable backend systems using multiple frameworks and languages. The ideal candidate will have 4+ years of experience working with at least two backend frameworks and be proficient in at least two programming languages such as Python, Node.js, or Go. As an Sr. Backend Developer, you will play a critical role in designing, developing, and maintaining backend services, ensuring seamless real-time communication with WebSockets, and optimizing system performance with tools like Redis, Celery, and Docker.

Key Responsibilities:

• Design, develop, and maintain backend systems using multiple frameworks and languages (Python, Node.js, Go).
• Build and integrate APIs, microservices, and other backend components.
• Implement real-time features using WebSockets and ensure efficient server-client communication.
• Collaborate with cross-functional teams to define, design, and ship new features.
• Optimize backend systems for performance, scalability, and reliability.
• Troubleshoot and debug complex issues, providing efficient and scalable solutions.
• Work with caching systems like Redis to enhance performance and manage data.
• Utilize task queues and background job processing tools like Celery.
• Develop and deploy applications using containerization tools like Docker.
• Participate in code reviews and provide constructive feedback to ensure code quality.
• Mentor junior developers, sharing best practices and promoting a culture of continuous learning.
• Stay updated with the latest backend development trends and technologies to keep our solutions cutting-edge.

Required Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent work experience.
• 4+ years of professional experience as a Backend Developer.
• Proficiency in at least two programming languages: Python, Node.js, or Go.
• Experience working with multiple backend frameworks (e.g., Express, Flask, Gin, Fiber, FastAPI).
• Strong understanding of WebSockets and real-time communication.
• Hands-on experience with Redis for caching and data management.
• Familiarity with task queues like Celery for background job processing.
• Experience with Docker for containerizing applications and services.
• Strong knowledge of RESTful API design and implementation.
• Understanding of microservices architecture and distributed systems.
• Solid understanding of database technologies (SQL and NoSQL).
• Excellent problem-solving skills and attention to detail.
• Strong communication skills, both written and verbal.

Preferred Qualifications:

• Experience with cloud platforms such as AWS, Azure, or GCP.
• Familiarity with CI/CD pipelines and DevOps practices.
• Experience with GraphQL and other modern API paradigms.
• Familiarity with task queues, caching, or message brokers (e.g., Celery, Redis, RabbitMQ).
• Understanding of security best practices in backend development.
• Knowledge of automated testing frameworks for backend services.
• Familiarity with version control systems, particularly Git.

The tech stack looks like the below (expect this to change as we scale):

1. Typescript for APIs (REST and GraphQL)
2. Kafka, Spark, and data warehouses for ML pipelines (spark on python/scala)
3. Solidity + hardhat for smart contracts (in the future, rust, go and move)
4. AWS & Terraform
5. Full nodes

You can expect to do some or all of the following:

1. Read through protocols’ whitepapers and smart contracts to derive metrics and analyze risks
2. Architect the backend for APIs, async jobs, and blockchain integration
3. Build clean, concise APIs for customer integration, along with the documentation
4. Setup, run and maintain full and archive nodes across different chains
5. Integrate with multiple partners like exchanges and custody providers
6. Fool-proof security across the stack - encryption, hashing, privacy, VPC, etc.
7. Infrastructure as code - build terraform scripts and ensure easy replication of the infra across different regions
8. Research the top DeFi protocols to uncover better insights for our customers and evaluate their risk profiles, security, and historical returns
9. 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.

1. Generalist, a solid engineer who can learn things on your own and have an eye for clean, tested, and well-documented code
2. 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
3. Understand the fundamentals of building and integrating APIs and secure systems. Bonus if you know a bit about blockchains and protocols
4. 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.
