A back end developer is a computer science professional who specializes in functionality that takes place on the server side or backend. As a back end developer, you write code to create software that solves a business need. Your responsibilities are to research the needs of either your employer, or a particular industry, find a problem, and create a software solution. A back end developer differs from a traditional web developer, or front end developer, in that back-end software may not have a user interface or even have exposure to the web.
| Aspect | Back End Developer | Front End Developer |
|---|---|---|
| Primary Focus | Server-side logic, databases, APIs | User interface, website layout, client-side scripting |
| Skills & Technologies | Languages like Java, Python, Ruby; databases; server management | HTML, CSS, JavaScript, frameworks like React or Angular |
| Work Environment | Backend systems, server environments, cloud platforms | Design tools, browser testing, UI/UX design |
| Common Certifications | Certified Web Developer, AWS Certified Developer | Certified Front End Developer, UI/UX certifications |
Back End Developers focus on server-side logic, databases, and APIs, ensuring the website's functionality behind the scenes. Front End Developers work on the visual and interactive aspects users see and interact with. Both roles are essential in web development, often collaborating to create seamless digital experiences.

Blockchain Infrastructure / Web3
Our clients are building transaction-heavy, performance-critical systems. They are looking for engineers who think in systems, take full ownership of what they ship, and are comfortable working close to the protocol.
This is a backend and systems-focused role.
As a Senior Backend Solana Engineer, you will design, build, and maintain production-grade Solana programs and the backend infrastructure that supports them. You will be deeply involved in architecture decisions, performance optimization, and security considerations for live systems used at scale.
You will work alongside senior engineers, product, and infrastructure teams to ship reliable, secure, and scalable Solana-based systems.
Design, develop, and ship production Solana programs using Rust
Own backend and systems architecture for transaction-heavy environments
Build and maintain backend services and APIs (gRPC, REST) supporting on-chain activity
Work with PostgreSQL and Redis for schema design, performance tuning, and debugging
Implement observability, testing, and benchmarking across systems
Contribute to security-first development practices in blockchain and financial contexts
Mentor other engineers and provide technical direction when needed
Required
Strong, hands-on experience with Rust in production environments
Proven experience building and shipping Solana programs or dApps
Deep understanding of backend systems and distributed architectures
Experience with APIs, multi-service systems, and data-intensive workloads
Familiarity with cloud infrastructure (AWS or GCP), Docker, and CI/CD pipelines
Ownership mindset with the ability to operate in fast-moving, ambiguous environments
Nice to Have
Experience with DeFi protocols or blockchain infrastructure
Background in fintech, trading systems, or high-throughput platforms
Familiarity with Solana RPC clients, transaction handling, and on-chain concepts
Competitive senior-level compensation
High-impact role with real technical ownership
Opportunity to work on production-grade Solana infrastructure
Fully remote teams with experienced engineers
Exposure to complex, real-world blockchain systems
If you are a backend-focused Solana engineer looking to work on meaningful, production systems, we would be happy to share more details and explore fit confidentially.
