Job Description
About the Role
At Pavago, one of our clients is hiring an experienced Full-Stack Software Engineer to design, build, and maintain modern web applications across frontend and backend systems.
This is a hands-on engineering role for someone comfortable working across the full development lifecycle — from building user-facing applications and backend services to designing APIs, working with databases, troubleshooting production issues, and supporting cloud deployments.
You’ll collaborate with product, design, and engineering stakeholders while using modern development practices and AI-assisted engineering tools to ship reliable, scalable software.

- Troubleshoot bugs and production issues
- Implement testing and development best practices
- Participate in technical planning and code reviews
- Improve application reliability and maintainability
- Help identify technical issues before they affect users
Cloud, Deployment & Development Workflows
- Work with cloud infrastructure and deployment workflows
- Support application releases and production deployments
- Use Git and version-control best practices
- Contribute to reliable development and deployment processes
AI-Assisted Software Development
- Use modern AI development tools to improve engineering productivity
- Apply AI-assisted workflows to coding, debugging, research, and development
- Evaluate new AI development capabilities where they can improve execution
- Maintain strong engineering judgment while using AI-assisted tools
Requirements
- 3+ years of professional software development experience
- Strong experience with at least one modern frontend framework
- Backend development experience using a modern programming language and/or framework
- Experience with SQL and/or NoSQL databases
- Hands-on experience building or integrating APIs
- Strong Git and version-control experience
- Familiarity with cloud platforms and deployment workflows
- Strong debugging and problem-solving skills
- Ability to write clean, maintainable, and scalable code
- Strong communication and collaboration skills
- Professional working English

Nice to Have
- Experience with AI-assisted development tools
- Experience building production-grade full-stack applications
- Experience with third-party API integrations
- Familiarity with automated testing and CI/CD workflows
- Experience working with cloud-native applications
- Experience collaborating directly with product and design teams
What Makes You a Strong Fit
You’ll likely thrive in this role if you:
- Enjoy building across both frontend and backend systems
- Take ownership of features from development through deployment
- Write code with scalability and maintainability in mind
- Can independently troubleshoot technical problems
- Communicate effectively with both technical and non-technical stakeholders
- Are comfortable learning new technologies quickly
- Use AI development tools thoughtfully to improve speed and productivity
What a Typical Day Looks Like
Your day may include developing frontend features, building backend services, integrating APIs, working with databases, reviewing code, and troubleshooting application issues.
You may also participate in technical planning, collaborate with product and design stakeholders, support deployments, and use AI-assisted development tools to accelerate coding and problem-solving.
In short: you build, improve, and maintain reliable web applications across the full technology stack.
Key Metrics for Success
- Consistent delivery of reliable application features
- Clean, maintainable, and scalable code
- Stable frontend and backend systems
- Reliable API and third-party integrations
- Effective debugging and resolution of production issues

💬 Potential Interview Questions
How would you design a maintainable full-stack feature from a product requirement through deployment?
I would clarify the requirements, define the API and data model, implement the frontend and backend in small testable units, and add automated tests. I would then review the change, deploy it through the established CI/CD workflow, and monitor it in production.
How do you structure a frontend application built with a modern component-based framework?
I separate reusable UI components, feature-specific components, application state, API services, and shared utilities. I also keep business logic out of presentation components where possible and use clear boundaries to improve testability and maintainability.
What considerations are important when designing a REST API for scalability and reliability?
I use consistent resource naming, HTTP semantics, validation, appropriate status codes, pagination, authentication, and predictable error responses. I also consider versioning, idempotency, rate limiting, observability, and efficient database access.
How would you optimize a slow database query in a production application?
I would inspect the query execution plan, check indexes, review joins and filtering conditions, and measure the impact of each change. I would also evaluate pagination, caching, query batching, and whether the data model needs adjustment.
How do you handle failures when integrating with a third-party API?
I implement timeouts, retries with exponential backoff where safe, clear error handling, logging, and circuit-breaking or fallback behavior when appropriate. I also isolate the integration behind a service layer so external API changes do not spread throughout the application.
What testing strategy would you use for a full-stack web application?
I would combine unit tests for business logic, integration tests for APIs and persistence, and end-to-end tests for critical user workflows. Tests should run automatically in CI, with additional checks for validation, authorization, error handling, and regression-prone areas.
How would you investigate a production issue affecting both frontend and backend behavior?
I would reproduce the issue if possible, inspect logs, metrics, traces, recent deployments, and relevant client-side errors, then narrow the problem to a specific layer. After applying and validating a fix, I would document the root cause and add monitoring or tests to prevent recurrence.
What Git workflow and practices do you use when collaborating on a remote engineering team?
I use focused branches, small commits, descriptive messages, pull requests, and peer reviews before merging. I keep branches synchronized, resolve conflicts carefully, and use automated checks to protect the main branch.
How do you design a cloud deployment workflow that is reliable and repeatable?
I automate builds, tests, configuration, and deployments through CI/CD, while keeping environment-specific settings in secure configuration management. I also use health checks, deployment monitoring, rollback procedures, and gradual releases when the system’s risk justifies them.
How do you use AI-assisted development tools without compromising code quality?
I use AI tools for research, boilerplate, debugging hypotheses, and test generation, but I verify all output against requirements, security standards, and project conventions. I run tests, review the generated code carefully, and remain accountable for the final design and implementation.
