Senior Python Flask Developer information

What are Senior Python Flask Developers?

Senior Python Flask Developers are experienced software engineers who specialize in building web applications using the Python programming language and the Flask web framework. They are responsible for designing, developing, and maintaining scalable backend systems, APIs, and web services. In addition to strong coding skills, they often lead projects, mentor junior developers, and ensure best practices in code quality, security, and performance. Their expertise allows them to solve complex technical challenges and contribute to the overall architecture and success of software projects.

What are some common challenges faced by Senior Python Flask Developers when working on large-scale applications?

Senior Python Flask Developers often encounter challenges such as managing complex codebases, ensuring scalability, and maintaining performance as applications grow. Integrating Flask with other technologies (like databases, caching systems, or third-party APIs) can introduce architectural complexities. Additionally, balancing rapid development with writing maintainable, well-tested code is crucial. Collaboration with frontend developers, DevOps, and QA teams is frequent, requiring strong communication and problem-solving skills.

What is the difference between Senior Python Flask Developer vs Python Developer?

AspectSenior Python Flask DeveloperPython Developer
Required CredentialsBachelor's in CS or related, experience with Flask, REST APIsBachelor's in CS or related, basic Python knowledge
Work EnvironmentWeb development teams, startups, tech companiesSoftware development teams, startups, tech companies
Employer & Industry UsageTech firms, SaaS companies, startupsVariety of industries including finance, healthcare, tech
Search & Comparison IntentAdvanced roles, leadership, project scopeEntry to mid-level development, learning

The main difference between a Senior Python Flask Developer and a Python Developer lies in experience and responsibilities. Senior developers typically have more expertise in Flask, lead projects, and mentor junior staff, whereas Python Developers may focus on coding and basic application development. Both roles are essential in web development teams, but senior roles require deeper knowledge and leadership skills.

What are the key skills and qualifications needed to thrive as a Senior Python Flask Developer, and why are they important?

To thrive as a Senior Python Flask Developer, you need advanced proficiency in Python, deep understanding of the Flask framework, and experience designing scalable backend architectures, typically supported by a degree in computer science or related field. Familiarity with RESTful API development, database management systems like PostgreSQL or MySQL, and version control tools such as Git is essential, and certifications in cloud platforms or web development can be beneficial. Strong problem-solving skills, clear communication, and the ability to mentor junior developers are standout soft skills for this role. These abilities ensure efficient delivery of robust, maintainable web applications and foster productive collaboration within development teams.

Full-time

Job description

Join Simbex as a Senior Software Engineer - Cloud Services and help build and modernize the backend systems behind our connected-device and sensor-analytics platforms. Our work lives where hardware meets software in demanding, real-world settings including connected safety and sports-performance products where device data has to be captured reliably and turned into trustworthy insight. You will own significant parts of a cloud platform that ingests real-time device data, exposes it through well-designed APIs, and supports the analytics products our customers depend on.
Key Responsibilities
  • Lead design and evolution of the backend services and REST APIs that ingest, route, and serve device sensor data, balancing day-to-day delivery with long-term platform health
  • Build and operate serverless services on AWS: primarily Lambda, API Gateway, and managed databases for scalable, cost-efficient cloud workloads
  • Help modernize the platform toward event-driven patterns, introducing asynchronous messaging and streaming (e.g., SQS/SNS, Kinesis, or Kafka) where they improve reliability and scale
  • Design and optimize relational databases (PostgreSQL on RDS) for high-throughput sensor data storage and demanding query workloads, applying solid schema design, indexing, and performance tuning
  • Define and maintain clear API contracts between internal services, device clients, and external platform consumers
  • Implement authentication, authorization, and security best practices across APIs and cloud services (OAuth 2.0, API Gateway, IAM)
  • Instrument services with structured logging, metrics, and distributed tracing to support observability and proactive incident response
  • Drive engineering maturity: CI/CD, automated testing, and code-quality standards. Lead design reviews as part of the team's formal review process
  • Write clean, modular, well-tested code (unit, integration, and contract tests) and set the standard for quality across the codebase
  • Collaborate with firmware, algorithm, and data teams to align on device communication protocols, data contracts, and platform SLAs, working within an Agile/SAFe delivery model
  • Mentor engineers and help shape the technical direction, standards, and best practices of the platform

Required Qualifications
  • 6+ years of professional backend or cloud software engineering experience, including time in a senior or technical-lead capacity
  • Bachelor's degree in Computer Science, Software Engineering, or a related technical field - or equivalent professional experience
  • Strong proficiency in Node.js/TypeScript and Python for building production backend services
  • Hands-on experience with core AWS services: Lambda, API Gateway, RDS, S3, and SQS/SNS
  • Experience designing and operating serverless or service-oriented architectures in production
  • Solid understanding of RESTful API design principles, versioning, and contract-first development
  • Strong relational database skills (PostgreSQL or similar) - schema design, indexing, query optimization, and performance tuning
  • Demonstrated ability to lead technical design, mentor engineers, and drive decisions across cross-functional teams
  • Familiarity with CI/CD practices and tooling (GitHub Actions, Jenkins, or similar)
  • Experience working in an Agile environment (Scrum, Kanban, or SAFe)

Preferred
  • Experience with IoT connectivity protocols: MQTT, AMQP, or AWS IoT Core
  • Experience with containerization and orchestration (Docker, ECS, or Kubernetes)
  • Experience with infrastructure-as-code tooling: Terraform, AWS CDK, or CloudFormation
  • Experience introducing event-driven or streaming architectures (Kafka, Kinesis, or similar) into an existing platform
  • Familiarity with observability platforms: OpenTelemetry, Datadog, Grafana, or AWS CloudWatch
  • Experience with API contract testing frameworks such as Pact or similar
  • Background in connected devices, wearables, sensor-data platforms, or other high-reliability or regulated domains
