We're looking for a Senior Software Engineer to join our engineering team and work on a large-scale production application.
This is an excellent opportunity for someone who enjoys solving complex technical challenges, working on modern technologies, and taking ownership of products used by real users.
You'll be joining an existing engineering team to help accelerate the development of one of our flagship products.
The application is already in production and includes:

• Next.js frontend
• PostgreSQL database
• Existing MongoDB components (currently being migrated)
• Multiple third-party API integrations
• Background jobs & queues

• Dockerized infrastructure
• CI/CD pipelines
• Cloud-based deployment
You'll work closely with our existing DevOps engineer to improve deployments, infrastructure, scalability, and application performance.
This role is ideal for someone who enjoys understanding complex systems and improving them rather than simply building small applications from scratch.
