Principal Software Architect (Python)

Описание вакансии

Rumble is a high-growth video platform and cloud services provider that is creating an independent infrastructure. Our mission is to restore the internet to its roots by making it free and open once again.

Rumble Cloud is seeking a Principal Software Architect (Python) to own the design and hands-on implementation of our Self-Service Cloud Portal and Cloud Console, the primary interfaces customers use to manage their cloud environments. Our stack is built on OpenStack and Ceph, with a customer surface that includes a self-service portal, an enhanced open-source cloud console, and integrated CRM/ERP-based billing and account management.

This role combines architectural leadership with significant day-to-day coding. You will define the architectural roadmap, guide the team in building scalable, maintainable services, and personally deliver high-quality Python code. Partnering with backend, Golang, and React/TypeScript teams, you will ensure cohesive design, strong performance, and an excellent developer and customer experience, while helping prioritize work and mentoring engineers without direct people management responsibilities.

Key Responsibilities

Architecture and Technical Vision

• Define, document, and communicate architectural patterns, standards, and best practices for backend services, microservice integration, and portal-wide interoperability.

• Evaluate the current codebase (including CRM/billing integration and cloud console frontend) and chart a practical path toward a scalable, maintainable architecture.

• Design architectures that support multi-tenant SaaS scale, observability, reliability, and future extensibility.

• Maintain architecture diagrams, service specifications, and operational design records for cross-functional transparency.

• Collaborate with platform and infrastructure teams to align service design with Rumble Cloud OpenStack/Kubernetes-based runtime environment.

Hands-On Development

• Contribute clean, efficient Python code (e.g., FastAPI, SQLAlchemy, Jinja2) for key backend components; this role requires sustained coding, not occasional guidance.

• Build and extend backend functionality that interfaces with RESTful APIs and SQL databases.

• Partner with Golang service teams and frontend developers (React/TypeScript) for seamless integration across the product ecosystem.

• Analyze product requirements and implement new features end-to-end, proactively identifying and addressing potential issues.

Planning, Prioritization, and Delivery

• Translate product-level requirements and customer needs into actionable roadmaps, epics, and tickets.

• Help prioritize features and technical debt based on impact, dependencies, and realistic timelines.

• Drive continuous improvement in the delivery lifecycle, including code review practices, release automation, and GitHub/GitHub Actions workflows.

• Help design and implement an SDLC and SSDLC with repeatable processes for planning, development, testing, deployment, and security review.

• Identify risks and blockers early and work with stakeholders to resolve them before they affect delivery.

Mentorship and Team Guidance

• Guide senior and mid-level engineers through design reviews, pair programming, and technical planning.

• Document designs and mentor engineers to grow their architectural thinking and engineering skills.

• Communicate technical decisions and trade-offs clearly to both engineering and non-technical stakeholders.

• Collaborate with other teams and departments on integrating new functionalities and services.

Qualifications

Required Qualifications

• Expert-level Python development experience, including SQLAlchemy, Jinja2, and modern API frameworks (e.g., FastAPI, Flask, Gunicorn).

• Strong experience designing and implementing RESTful APIs and resource servers, including working with incomplete or minimal SDK documentation.

• Experience designing and implementing authentication and authorization mechanisms such as OAuth2 and OpenID Connect.

• Strong understanding of relational databases (PostgreSQL, MySQL), ORM patterns, and schema design.

• Demonstrated experience architecting distributed systems or service-oriented architectures at production scale.

• Proficiency with object-oriented and functional programming concepts.

• Proficiency with containerized development (Docker) and cloud-native deployment environments (Kubernetes).

• Hands-on familiarity with Git-based workflows, including GitHub, pull requests, and CI/CD pipelines.

• Ability to synthesize product-level requirements into actionable technical roadmaps and system designs.

• Excellent communication and mentoring skills, with a track record of guiding engineering teams toward delivery excellence.

• Demonstrated ability to act as a hands-on technical leader while maintaining architectural oversight across multiple services and teams.

• Strong problem-solving and debugging skills across complex, distributed systems.

• Ability to work effectively in a fast-paced environment, balancing immediate delivery needs with long-term architectural goals.

• Willingness to learn, be challenged, and contribute in a dynamic, fast-paced environment, with a passion for cloud-native development and open-source tooling.

Preferred Qualifications

• Strong Go (Golang) programming experience, with the ability to contribute to and review Go-based services.

• Familiarity with OpenStack APIs, services, or the broader OpenStack ecosystem.

• Familiarity with Ceph or other distributed storage systems.

• Experience with the Odoo ERP/CRM platform, including module development, customization, or integration into SaaS products.

• Background working with or extending open-source cloud console or dashboard projects.

• General familiarity with public cloud concepts (e.g., AWS, Google Cloud, Microsoft Azure).

• Experience building SaaS in a multi-tenant environment, including tenant isolation, usage metering, and self-service provisioning.

• Experience with OpenStack or Kubernetes API development, control panel design/architecture, and test-driven development with Pytest.

• Experience working within public cloud / IaaS products.
