What is a contract backend developer?

Contract backend developers are professionals hired on a temporary or project basis to build and maintain the server-side logic, databases, and APIs that power web or mobile applications. They work behind the scenes to ensure that applications function smoothly, handle data efficiently, and communicate effectively with front-end systems. Unlike full-time employees, contract backend developers typically work for a set duration or on specific projects, offering flexibility to both clients and developers. They often bring specialized expertise in programming languages such as Python, Java, Node.js, or Ruby, and may work remotely or on-site depending on the contract terms.

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

To thrive as a Contract Backend Developer, you need strong programming skills in languages like Python, Java, or Node.js, along with experience in database management and API development, supported by a relevant degree or proven project experience. Familiarity with frameworks (such as Django, Spring, or Express), cloud services (like AWS or Azure), and version control systems (e.g., Git) is typically expected. Excellent problem-solving abilities, strong communication, and the ability to quickly adapt to new codebases and team environments set top contractors apart. These skills and qualities are crucial for delivering reliable, scalable backend solutions and integrating smoothly into diverse project teams.

What are some common challenges faced by contract backend developers when joining a new project?

Contract Backend Developers often encounter challenges such as quickly understanding existing codebases, adapting to different tech stacks, and aligning with the team's development practices. Since contract roles usually have tight deadlines, developers must rapidly familiarize themselves with project documentation and workflows. Effective communication with team members and proactive clarification of requirements are essential to ensure smooth integration and successful project outcomes.

Job description

Job Summary
We are seeking a Senior Backend Developer to design implement and refactor core platform services supporting federated authentication and a multi-entity vehicle management system. This role focuses on integrating Firebase-based identity restructuring backend data models and modernizing API layers to support scalable account vehicle and profile relationships.
Responsibilities
  • Data Model & Persistence Layer
  • Design and implement new domain entities including user_account and vehicle_profile to support federated identity mapping.
  • Refactor existing schemas (e.g.vehicle_enrollment) to separate vehicle-level and profile-level concerns.
  • Develop and execute database migrations including:
  • Table creation column restructuring and foreign key repointing
  • Index updates and performance optimizations
  • Implement data backfill and reconciliation logic for existing records including consolidation of vehicle and profile relationships.

API & Middleware Development
  • Refactor REST APIs to support:
  • Account-level vehicle-level and profile-level operations
  • Updated relationships between entities (account-vehicles-profiles)
  • Implement cross-cutting concerns:
  • Request interceptors/filters for authentication and context resolution
  • Shared request context updates (vehicleProfileId userAccountId)
  • Enhance API contracts OpenAPI documentation and error handling to reflect new data model and authentication patterns.

Authentication & Security Integration
  • Integrate Firebase Authentication and implement ID-token validation and claim extraction.
  • Transition from client-credential-based authentication (e.g. Keycloak) to federated identity model.
  • Implement account-ownership authorization to enforce access control across account vehicle and profile scopes.

Service Layer & Business Logic
  • Rework service logic to support:
  • Vehicle enrollment and profile creation flows
  • Signing key management and rotation
  • Payment/card binding at profile level
  • Update transaction processing logic to distinguish between:
  • Profile-based signed transactions
  • Vehicle-level fallback scenarios
  • Implement account-level operations such as:
  • Full account closure with cascading vehicle unenrollment and partial failure handling
  • Work with third-party integrations including:
  • Firebase (identity provider)
  • MasterCard SRC (card tokenization and identity binding)
  • Payment middleware and BOS systems
  • Ensure consistency of entity mapping across internal services and external callbacks.

Testing & Quality Engineering
  • Develop and execute integration and regression test plans across:
  • Updated schema and foreign key relationships
  • API endpoints and authentication flows
  • Update test teardown and data lifecycle logic to reflect new entity relationships.
  • Strong experience in backend development (Java/Spring Boot or similar frameworks)
  • Proven expertise in:
  • REST API design and refactoring
  • Relational database design schema migrations and indexing
  • Authentication/authorization frameworks (JWT OAuth federated identity)
  • Experience implementing middleware components such as interceptors filters and request contexts
  • Familiarity with cloud-based identity providers (e.g. Firebase Auth OAuth providers)
  • Experience with payment systems and tokenization (e.g. MasterCard SRC or similar)
  • Prior work on multi-tenant or hierarchical data models (account-asset-profile)
  • Knowledge of event-driven integrations and callback-based third-party systems
  • Experience with API gateways and distributed security validation patterns
  • Strong system design and data modeling skills
  • Ability to manage complex refactoring across multiple layers (DB API service)
  • Attention to data integrity security and backward compatibility
  • Effective collaboration across architecture QA and integration teams
  • End-to-end ownership of a major platform refactor spanning:
  • Data model redesign
  • Authentication transformation
  • API and service re-architecture
  • Direct impact on enabling scalable multi-vehicle multi-profile user experiences
  • Critical role in aligning platform architecture with federated identity standards and payment constraints
