Senior Python Developer

Job Title: Senior Python Developer

Direct Manager: Team Lead / Manager

About the role:

We're looking for a seasoned backend engineer to take ownership of architecture and implementation across our Python-based platform. You'll be making high-level technical decisions, mentoring engineers, and working across the full stack — from cloud infrastructure to external-facing APIs.

This is a senior individual contributor role with meaningful influence over system design and engineering culture. You'll work closely with Business Analysis, Marketing, and cross-functional product teams to deliver robust, scalable software.

Job Functions & Responsibilities:

Responsibilities

• Own architectural decisions for software design and implementation; serve as a technical authority on the team.
• Handle the full SDLC — design, development, testing, debugging, and deployment.
• Provide mentorship and technical guidance to developers and engineers.
• Work closely with product, BA, and marketing stakeholders to deliver fully-featured products for both external customers and internal staff.
• Participate in design reviews, progress meetings, and technical troubleshooting sessions.
• Read, understand, and improve code written by others — including legacy systems.
• Produce thorough technical documentation and uphold engineering standards.
• Support customers and internal teams on technical escalations — you'll be a resource, not a helpdesk.

What We're Looking For

• Strong analytical and problem-solving ability; rigorous attention to detail.
• Ability to translate business requirements into clean, maintainable, well-documented code.
• Excellent written and verbal communication in English.
• Comfort operating across ambiguity and competing priorities.
• Deep understanding of modern system architecture, distributed systems, and cloud-native patterns.

Required Knowledge & Experience:

• 10+ years’ general programming experience, with 7+ years’ experience in Python 3.
• 7+ years developing web-oriented APIs and backend systems.
• 5+ years’ operating and developing in a Linux environment.
• 3+ years’ experience with AWS IaC, Code Pipeline, Terraform etc.
• Strong experience with PostgreSQL.
• Strong experience with key-value/data-structure stores, especially Redis.

Also required:

• Python web frameworks: Django, Flask, FastAPI, or similar.
• Service-oriented architecture and messaging patterns (req/rep, pub/sub).
• Testing practices and tooling (unit, integration, coverage).
• Git and modern source control workflows.
• Experience with service-oriented architecture and common messaging patterns (eg: req/rep, pub/sub).
• Experience with Python-based web frameworks such as Django, Flask, or Bottle.

Nice to Have

• Elasticsearch or Splunk for search and log analytics.
• Kubernetes or other cloud orchestration platforms.
• OpenAPI / Swagger specification and documentation.
• Stream-processing tools (Kafka, Kinesis, Flink, etc.).
• CI/CD tooling: TeamCity, Jenkins, Octopus, GitHub Actions.
• Modern JS frameworks: React, Vue, Angular.
• Agile/Scrum methodology and experience in sprint-based teams.
• Exposure to alternative Python runtimes such as PyPy.
• Understanding data ingest and transformation pipelines, event sourcing, and CQRS patterns.
• Experience working in regulated sectors (e.g. financial services, healthcare, government) with awareness of compliance, audit trails, and data governance requirements.
