Before You Apply — A Message from Our Founder

For generations, women have navigated systems never built with them in mind. The gaps in leadership, health, wealth, and opportunity were engineered into the world we inherited—and now, for the first time, we have the tools to build something better. AI gives us the chance to design technology that truly partners with the women and organizations working tirelessly to advance women and girls. Being trusted to do this work is both a privilege and a responsibility, and I am looking for people who feel that responsibility as deeply as I do.

Uplevyl is not a conventional workplace. We have a distinct culture. We exist to create meaningful impact for society, and we hold ourselves to a standard of moving fast while delivering quality that endures. We partner only with those who share our commitment to doing important work, and we build technology that opens doors, expands opportunity, and enables more people to participate and benefit.

We hire only A-players and compensate them accordingly. We do not compromise on talent, and we part ways respectfully when performance does not meet the standards required by our mission. Everyone at Uplevyl wears multiple hats. No task is beneath anyone. Decisions are driven by merit, not hierarchy. We prioritize customers over internal convenience, avoid politics, and maintain zero tolerance for unnecessary bureaucracy.

We move with urgency because the mission demands it. When the work calls for it, we stretch beyond traditional hours—not out of obligation, but out of genuine commitment to building something transformative. We look for people energized by bold problems, people who find meaning in momentum and possibility, and who bring a proactive, high-ownership mindset to everything they do. If you thrive in environments where innovation, purpose, and high standards come together, you will feel at home at Uplevyl.

Job Description

The Backend Engineer will design, develop, and maintain high-performance backend services for large-scale, multi-tenant SaaS platforms. The role requires strong expertise in Python frameworks and cloud-based microservices architecture, with a focus on scalability, security, and performance optimization.

Key Responsibilities:

  • Design, develop, and maintain high-performance backend services for large-scale, multi-tenant SaaS platforms. 

  • Build REST/GraphQL APIs using Python frameworks such as FastAPI or Flask. 

  • Work with PostgreSQL/MySQL and NoSQL databases (MongoDB/DynamoDB), ensuring efficient schema design and performance tuning. 

  • Implement microservices architecture using Docker and Kubernetes. 

  • Develop event-driven workflows using Kafka, RabbitMQ, Kinesis, or similar message queues. 

  • Leverage AWS cloud services (Lambda, ECS, RDS, S3, Cognito) to build scalable and secure backend systems. 

  • Apply Clean Architecture / Hexagonal Architecture principles with strong design pattern implementation. 

  • Implement observability (logging, metrics, tracing) to ensure system reliability. 

  • Contribute to CI/CD pipelines and automation for efficient deployments. 

  • Conduct code reviews to maintain clean, high-quality code and enforce engineering best practices. 

  • Ensure backend security standards including SAST, DAST, and secure coding guidelines. 

Primary Qualifications

  • 5-7 years of experience as a Backend Engineer working with Python. 

  • Hands-on experience in FastAPI or Flask. 

  • Excellent programming, problem-solving, and system design skills. 

  • Hands-on experience with PostgreSQL/MySQL, Redis caching, and optionally DynamoDB/MongoDB. 

  • Strong understanding of microservices and containerization (Docker/Kubernetes). 

  • Experience with AWS ecosystem (Lambda, ECS, RDS, S3, Cognito). 

  • Experience with event-driven architectures (Kafka/RabbitMQ/Kinesis). 

  • Strong understanding of Clean/Hexagonal architecture and design patterns. 

  • Exposure to CI/CD pipelines, backend testing frameworks, and code quality tools. 

  • Knowledge of observability practices and tools. 

Desired Qualifications 

  • Awareness, exposure, or hands-on experience with AI models, API integrations, fine-tuning, or model-driven workflows is a strong advantage. 

  • Proactive, self-driven, innovative, and a strong team player. 

Cultural & Work-Style Skills 

1. Ego Less, Impactful Collaborative Contribution
You collaborate across disciplines, share knowledge openly, and welcome feedback on architecture, code, and decisions. You care more about building the right system than about being “right”.

2. Ownership From Design to Delivery
You think beyond tickets. You take responsibility for the full lifecycle of what you build including architecture, implementation, testing, reliability, and iteration. You solve problems end-to-end rather than waiting for perfect specifications.

3. Mission-Driven Urgency With Technical Depth
You move quickly when needed, but never at the expense of long-term stability. You can distinguish when to build fast and when to build right and you communicate trade-offs clearly.

4. Agility in Ambiguity
You are comfortable building in evolving environments with partial information. You prototype, test assumptions early, reduce dependencies, and find creative paths through constraints.  

5. Purpose-Fueled Resilience & Curiosity
You stay steady when debugging complex issues, you learn rapidly, and you adapt as the product and architecture evolve. You draw energy from solving meaningful problems and building systems that open doors for millions of women.
