Responsibilities:

Software Development & Ownership

• Break down complex initiatives into clear, achievable deliverables.
• Contribute to the design and maintenance of SQL and/or document databases.

Technical Leadership & Architecture

• Provide technical leadership in architecture, design decisions, implementation, and code quality.
• Identify and resolve requirement gaps, reduce technical debt, and improve system maintainability.
• Research and evaluate new technologies to select optimal solutions.
• Contribute to shared codebases, architectural decisions, and engineering standards.

Collaboration & Delivery

• Work independently on small to medium projects and contribute to large cross-team initiatives with a Solution Architect.
• Lead small projects or support medium-sized initiatives.
• Facilitate discussions around user scenarios, technical trade-offs, and delivery optimization.
• Participate in initiatives impacting multiple teams.

Code Quality & Production

• Ensure high code quality through code reviews, pull requests, and pair programming.
• Support testing, performance planning, reliable releases, and production stability.

What you’ll get working with us:

• Short-term hourly-based contract (3–5 months) with a clear scope, transparent expectations, and a possibility of extension based on project needs and performance.
• Opportunity to work on globally adopted, large-scale production products used daily by millions of readers, students, and institutions worldwide.
• High-impact engineering work on mature, business-critical systems — not an MVP or experimental project.
• Collaboration with a strong, cross-functional product team, including experienced backend, frontend, QA engineers, architects, and product stakeholders.
• A senior-level engineering environment with a strong focus on code quality, architecture, scalability, and long-term maintainability.
• Modern technology stack, automated CI/CD pipelines, cloud infrastructure (Azure & AWS), and engineering best practices.
• Autonomy and ownership: real influence on technical decisions, architecture, and implementation.
• Fully remote work with a distributed, well-organized team.
• Professional, respectful communication and a well-established engineering culture.
• Valuable experience working with well-known US-based digital products that strengthen your professional profile.
