• Make services easier to operate by maintaining useful logs, metrics, dashboards, alerts, and runbooks.
• Contribute to React or Next.js integrations and internal administration interfaces when needed to deliver complete product outcomes.
• Collaborate with product, frontend, platform, DevOps, SRE, and operations teammates to ship well-scoped solutions and document technical decisions.

What we're looking for

Required

• 3–5 years of professional software engineering experience, mainly in backend development.
• Good proficiency in Python and production experience with either Django or FastAPI, with willingness to learn the other.
• Practical experience designing REST APIs and integrating with third-party or internal services.
• Working knowledge of SQL, relational databases, an ORM such as Django ORM or SQLAlchemy, and database migrations.
• Experience writing automated tests and diagnosing defects or production issues.
• Good problem-solving, communication, documentation, and collaboration skills.

Preferred

• Familiarity with background jobs or asynchronous processing using Celery, SQS, RabbitMQ, Kafka, or similar tools.
• Experience deploying or supporting applications on AWS or another cloud platform.
• Familiarity with structured logging, metrics, dashboards, alerts, and observability tools.
• Exposure to React or Next.js integrations.
• Experience with Docker, Redis, webhooks, queues, or event-driven systems.
• Familiarity with CI/CD pipelines, infrastructure-as-code, secrets management, and least-privilege access.
• Experience helping with production incidents, performance testing, or safe deployment practices.

What you’ll do here:

•Lead the technical implementation of our platform using Python for new and existing clients

•Collaborate with internal teams to deliver seamless onboarding experiences for our clients.

•Translate business use-cases into scalable, secure, and maintainable technical solutions

•Own the technical relationship with clients, acting as a trusted advisor throughout the implementation lifecycle

•Conduct code reviews, enforce best practices, and ensure high-quality deliverables

•Mentor developers and contribute to internal tooling and automation

•Troubleshoot and resolve complex integration issues across cloud environments
