What is a backend developer?

Backend Developers are software engineers who focus on building and maintaining the server-side logic, databases, and APIs that power websites and applications. They ensure that the data requested by frontend systems is delivered efficiently and securely. Their responsibilities include creating and managing databases, developing server-side application logic, integrating third-party services, and ensuring application performance and scalability. Backend Developers typically work with languages such as Java, Python, Ruby, Node.js, or PHP. They often collaborate with frontend developers, designers, and other team members to deliver complete, functional digital products.

What are some common challenges backend developers face when collaborating with frontend teams?

Backend Developers often encounter challenges related to syncing data structures, API endpoints, and release timelines with frontend teams. Ensuring clear communication and thorough documentation is critical to avoid mismatches in data expectations and functionality. Regular coordination through stand-up meetings, shared project management tools, and version-controlled API documentation helps mitigate misunderstandings and keeps both backend and frontend development aligned. Adopting practices like API-first development and automated testing can significantly improve collaboration and overall project quality.

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

To thrive as a Backend Developer, you need a strong grasp of server-side programming languages (such as Java, Python, or Node.js), database management, and software architecture concepts, often supported by a degree in computer science or a related field. Familiarity with frameworks (like Spring or Django), cloud platforms (AWS, Azure), APIs, and version control systems (Git) is typically required. Problem-solving ability, attention to detail, and effective teamwork are standout soft skills in this role. These skills ensure robust, scalable, and secure systems that effectively support the needs of users and front-end applications.

What is the difference between Backend Developer vs Frontend Developer?

Required SkillsProgramming languages like Java, Python, PHP; databases; server managementHTML, CSS, JavaScript; frameworks like React or Angular
Work EnvironmentBackend systems, server infrastructure, cloud servicesWeb browsers, design tools, user interface testing
Common UsageBuilding and maintaining server-side applicationsDesigning and implementing user interfaces

While both roles are essential in web development, Backend Developers focus on server-side logic and data management, whereas Frontend Developers create the visual and interactive aspects of websites. Understanding their differences helps in choosing the right career path or project collaboration.

What's a typical backend developer salary?

A backend developer's salary varies based on experience, location, and skills, but generally ranges from $70,000 to $120,000 annually in many regions. Senior developers with expertise in frameworks, databases, and cloud services can earn higher salaries, often exceeding $130,000. Entry-level positions typically start around $60,000 to $80,000.

Job description

About the Role

We're looking for a Cloud Backend Engineer to design, build, and operate the backend services behind a multi-tenant, event-driven cloud platform. You'll work across cloud services and device/edge connectivity, building reliable, scalable systems and owning them end-to-end from architecture and infrastructure-as-code through to production operations.

This is a hands-on, high-ownership role on a small, senior team. You'll write Go services, define your own AWS infrastructure in CDK, secure the API edge, and reason about the boundary between the device edge and the cloud.

What You'll Do

Design, build, and maintain backend services and APIs in Go, with supporting code and infrastructure in TypeScript.

Define and operate cloud infrastructure on AWS using CDK API Gateway, Lambda, SQS (including dead-letter/redrive queues), DynamoDB, S3, RDS/Aurora PostgreSQL, Cognito, CloudFront, and WAF.

Build and scale event-driven and device-to-cloud pipelines telemetry and data ingestion, content/command delivery, retries, and offload/consolidation processing.

Work across the cloud/edge boundary services and agents running on edge/embedded Linux, using AWS IoT Greengrass and MQTT messaging.

Strengthen multi-tenant isolation, identity, and security PostgreSQL Row-Level Security, OAuth2/JWT, API gateway authorizers and middleware, edge protection (CloudFront/WAF/Lambda@Edge), and encryption in transit and at rest (KMS/Secrets Manager).

Own reliability and observability structured logging with secret redaction, retry/back-off and idempotency, latency tracing, and diagnosing concurrency and load problems in ingestion and delivery paths.

Write and maintain CI/CD and security scanning Jenkins pipelines, Docker, and remediation of dependency/container findings (e.g., BlackDuck, Sysdig) across multiple environments.

Collaborate with architecture, firmware/edge, and product teams to define the API and data contracts between devices and the cloud.

Contribute to design reviews, participate in on-call/incident response, and help with release engineering for production systems.

What We're Looking For

Required:

Strong professional experience building backend services in Go and Node/Typescript (services, middleware, concurrency, testing).

Hands-on experience with AWS Lambda, API Gateway, SQS, DynamoDB, S3, IAM, Cognito, RDS/Aurora, CloudWatch and comfort operating what you build.

Experience writing infrastructure as code, ideally AWS CDK (TypeScript) (Terraform/CloudFormation experience translates).

Solid understanding of distributed systems event-driven architecture, message queues, retries/idempotency, dead-letter handling, eventual consistency, and fault tolerance.

Experience designing and securing multi-tenant SaaS backends tenant isolation, authn/authz (OAuth2, JWT), and API gateway patterns.

Working knowledge of PostgreSQL schema design, migrations, and query performance (Row-Level Security a strong plus).

Comfort with CI/CD and containerization Jenkins (or similar), Docker, and multi-environment promotion.

Strong debugging and observability instincts, and clear technical communication.

Nice to Have:

Experience with IoT / device-to-cloud systems AWS IoT Greengrass, MQTT, device provisioning, fleet management, and telemetry pipelines.
