What are the responsibilities and job description for the Junior Software Engineer position at TELIN?
We're looking for a motivated Junior Software Developer to join our engineering team and contribute to a Laravel-based telecom management platform. You'll work across a range of responsibilities — from building and maintaining core application features to supporting critical external integrations with different platforms VIA API. This is a hands-on role with real ownership from day one, supported by a structured onboarding process and close mentorship.
- Building and maintaining features across a Laravel 11 application (controllers, services, Eloquent models, Artisan commands)
- Supporting and extending integrations with third-party platforms VIA API
- Writing and maintaining automated tests (unit and feature) for changed or new behavior
- Working with cron-driven processing pipelines that power business-critical workflows
- Investigating and resolving issues using application logs and database-backed audit trails
- Contributing to engineering documentation and keeping it up to date as the system evolves
PHP & Laravel
- PHP 8 fundamentals and object-oriented programming
- Laravel fundamentals: routing, controllers, Eloquent ORM, middleware, and Artisan commands
- Comfort reading and navigating a modular codebase
Database
- MySQL fundamentals and awareness of multi-database environments
Frontend
- Basic JavaScript for working with existing frontend pages and assets
Tooling & Process
- Git workflow: feature branches, pull requests, and conflict resolution
- Command line usage for local setup and debugging, including SSH for remote server access
- Familiarity with Composer, npm, and PHPUnit
Data & Formats
- SQL queries: joins, filtering, aggregation, and basic schema changes
- Reading and working with structured JSON — particularly relevant for integration payloads
- Basic Python scripting for data extraction or local tooling tasks
- Familiarity with Go (Golang) — our monitoring server is written in Go; reading and making minor contributions is a plus
- Familiarity with .NET (C#) — some integration modules are .NET-based
- Familiarity with Apache configuration (virtual hosts, reverse proxy)
- Exposure to workflow orchestration tools (e.g., Apache Airflow)
- Understanding of telecom concepts such as SIP trunks, DID numbers, number porting, A2P messaging, or STIR/SHAKEN
Your onboarding is structured to build confidence progressively:
- Set up the local development environment and run the relevant PHPUnit test suite
- Deliver at least one supervised bug fix in a service class, with accompanying tests
- Deliver at least one supervised change to a cron command, with accompanying tests
- Analyze an integration payload from an integration using existing reference files
- Submit a documentation update to the engineering docs
- Demonstrate safe debugging using application logs and database audit records
- We ship small, well-scoped changes with clear pull request descriptions
- Tests are expected for any changed or new behavior — no exceptions
- Credentials and secrets never appear in code or documentation
- Logging is meaningful and follows established audit and security logging patterns
- Documentation is updated whenever behavior, command interfaces, or integration contracts change
- High-risk areas (billing, telephony, provisioning) are regression-tested before merging
- Backend Servers: PHP 8 , Laravel 11 mainly
- Monitoring Server: Go (Golang) as an example
- Integration Modules: .NET (C#)
- Database: MySQL (multiple connection environments)
- Frontend Services: Blade templates, JavaScript, Vite
- Integrations: Many and growing
- Orchestration: Apache Airflow
- Docs: MkDocs
- Testing: PHPUnit
