Your Work:

Feathr's SaaS platform is a critical component of the value we deliver to our clients. As a Principal Backend Software Engineer, you shape the technical direction of the systems that meet the advertising, marketing, and analytics needs of our diverse customer base. You operate across teams and time horizons—identifying systemic risks before they become incidents, driving architectural decisions that compound over years, and raising the bar for engineering quality across the organization. You balance hands-on technical work with strategic influence, and your judgment is trusted to make the right tradeoffs when the path forward is ambiguous.

Your Experience:

• 6+ years of backend software engineering experience

• 4+ years designing and operating distributed software systems at scale

• Track record of leading technical initiatives that span multiple teams or services

• Deep expertise in Python, Flask, Elasticsearch, MongoDB, and Redis

• Experience defining and evolving engineering standards, practices, and tooling for an organization

• Proficiency with AI-assisted development tools (e.g., Claude Code, GitHub Copilot, Cursor); we use these daily and consider them core to our workflow

Your Technical Skills:

• Design and evaluate system architectures with a focus on reliability, scalability, and operational cost

• Deep knowledge of data structures, algorithms, and their practical performance characteristics

• Expert-level proficiency with Elasticsearch—schema design, query optimization, cluster operations, and scaling strategies

• Expert-level proficiency with MongoDB—data modeling, aggregation pipelines, indexing strategies, and operational maintenance at scale

• Comprehensive knowledge of AWS infrastructure and services (EC2, EKS, SQS, S3, and beyond)

• Design and maintain event-driven architectures and data ingestion pipelines across diverse sources

• Strong understanding of security, compliance, and data governance in enterprise SaaS environments

• Define testing strategies that balance coverage, speed, and maintainability across a multi-service codebase

• Identify and drive adoption of AI-assisted development practices that meaningfully improve team velocity and code quality

• Nice to have: Experience with Docker, self-hosted Drone CI/CD, Kubernetes, Helm, programmatic advertising platforms, or capacity planning
  

Your Qualities:

• Pragmatic and customer-oriented—you build software to help customers solve real problems, and you help others do the same

• A systems thinker who sees how individual decisions compound across a codebase, a team, and an organization

• Decisive under ambiguity; you make sound technical calls with incomplete information and adjust when new facts emerge

• Exceptional communicator; you translate between business strategy and technical architecture fluently

• A force multiplier—you make every engineer around you more effective through mentorship, code review, design feedback, and tooling

• Opinionated but open-minded; you advocate strongly for your position and change your mind when presented with better evidence

• Patient with people, impatient with systemic problems; you invest in long-term fixes over recurring workarounds

• Service-oriented; you build sustainable systems and sustainable teams
  

Your Day:

• Drive architectural decisions that affect the platform's reliability, scalability, and long-term maintainability

• Design and implement high-impact backend features and services, particularly when the problem space is novel or ambiguous

• Identify systemic technical risks and lead efforts to address them before they become critical

• Mentor senior and mid-level engineers through design reviews, pairing, and direct feedback

• Collaborate with engineering leadership, product managers, and stakeholders to align technical strategy with business goals

• Set and raise the bar for code quality, testing practices, and operational excellence

• Evaluate build-vs-buy decisions, new technologies, and architectural patterns for the team

• Debug the hardest production issues—the ones that cross service boundaries and resist simple explanations

• Ensure the integrity, availability, and confidentiality of Feathr's data and operations
