System Design / Architecture

- Design end-to-end backend systems with a focus on scalability, resilience, and maintainability
- Define service boundaries, data ownership, and communication patterns
- Select and apply appropriate architecture patterns:
- Modular monoliths
- Microservices
- Event-driven systems
- Layered and hexagonal architectures

- Drive trade-off decisions (performance vs cost vs complexity)
- Produce architecture diagrams, ADRs, Data Flow Diagrams and technical design documents

Backend Engineering

- Design and develop high-performance backend services using Python and FastAPI
- Build and maintain RESTful APIs and async services
- Handle concurrency, background processing, and IO-heavy workloads
- Enforce clean code, SOLID principles, and testability
- Lead code reviews with a focus on correctness, performance, and long-term design

Data Engineering

- Design and optimize schemas in RDBMS (PostgreSQL/MySQL)
- Indexing, query optimization, transactions, isolation levels

- Design data models for NoSQL systems (MongoDB, DynamoDB, Redis, etc.)
- Choose the right data store based on access patterns and consistency needs
- Handle migrations, versioning, and backward compatibility

Distributed Systems

- Design systems that handle:
- Partial failures
- Retries, timeouts,



and idempotency
- Horizontal scaling

- Experience with message brokers and async communication (Kafka, RabbitMQ, SQS, etc.)
- Understand consistency models, eventual consistency, and data replication

DevOps / Cloud

- Work in cloud environments (AWS / Azure / GCP)
- Containerize services using Docker
- Deploy using CI/CD pipelines
- Understand Kubernetes concepts (pods, services, autoscaling) or managed alternatives
- Collaborate with DevOps/SRE on observability, logging, and monitoring

Technical Leadership

- Act as technical owner for backend systems
- Mentor senior and mid-level engineers
- Set engineering standards and best practices
- Work closely with product and business stakeholders to translate requirements into technical designs

Profile Description:

Must have

- 10+ years of backend/software engineering experience
- 3+ years of production experience with FastAPI
- Expert-level Python knowledge
- Robust experience with:
- Relational databases (PostgreSQL/MySQL)
- At least one NoSQL datastore

- Deep understanding of:

- Backend architecture patterns
- Design patterns (GoF, SOLID, DDD concepts)
- Distributed systems fundamentals

Additional qualifications

- Experience designing and evolving large-scale systems
- Practical experience with cloud services and deployments
- Proven ability to lead technical decisions and architecture discussions
- Experience migrating monoliths to microservices (or deciding not to)
- Event-driven or streaming systems experience
- API gateways, rate limiting, auth systems (OAuth2, JWT)
- Prior experience acting as Senior Backend Developer, Tech Lead or Solution Architect
