Participating in architecture discussions for new IoT products
Evaluating new devices, SDKs and integration approaches

Requirements

Commercial experience with IoT products or connected devices
Understanding of Bluetooth Low Energy (BLE)
Experience integrating hardware with mobile applications
Experience working with REST APIs
Understanding of networking fundamentals
Ability to debug communication between hardware and software
Experience reading technical documentation and SDKs
Strong analytical and troubleshooting skills
English level: Intermediate+ or higher

Nice to have

Experience with Android or iOS development
Experience with React Native or Flutter
Understanding of MQTT or WebSockets

Experience working with hardware manufacturers
Experience using oscilloscopes, BLE analyzers or similar diagnostic tools

What we offer

Opportunity to build a new technical direction inside the company
Flexible format (part-time or full-time)
Interesting international IoT projects
High level of ownership and technical autonomy
Direct impact on engineering decisions
Flexible working hours
Remote-friendly environment
Professional growth into Technical Lead or Head of IoT

Why join us?

We’re not looking for someone to maintain an existing department.

We’re looking for an engineer who wants to help create one.

If you’re excited about connected devices, mobile technologies and solving real-world integration challenges, we’d love to talk.

Middle Backend Software Engineer

26 Lines Of Code  is looking for an independent Middle Backend Software Engineer who is ready to take real ownership of complex backend development — including scalable microservices, cloud infrastructure, and robust enterprise security integrations.

This role is not for a simple task-executor. We expect an engineer who can make architectural decisions, optimize system performance, and keep the backend moving forward without constant supervision.

Responsibilities:

• Own backend delivery end-to-end: design, develop, and maintain high-performance Python applications.
• Build and scale: design microservices-based system architectures and robust REST APIs.
• Manage infrastructure: containerize applications using Docker and manage deployments in Kubernetes via Helm charts.
• Leverage AWS cloud services: utilize DynamoDB, IAM, Lambda, and API Gateway effectively.
• Implement security integrations: design and support Splunk solutions (Secure Gateway, Spacebridge) and build secure SSO/MFA authentication flows (SAML 2.0, Duo).
• Collaborate efficiently: work closely with frontend engineers (React) and DevOps teams to ensure smooth integration and delivery.

• Maintain data performance: utilize Redis for caching layers, session storage, and highly available setups.

   

Requirements:

• 3+ years of professional backend development experience using Python 3.
• Proven experience with AWS (specifically DynamoDB, IAM, Lambda, and API Gateway).
• Strong proficiency in containerization and orchestration: Docker, Docker Compose, Kubernetes, and Helm.
• Solid experience with Redis for caching and session management.
• Hands-on experience with Splunk (Dashboard Studio/Classic, Secure Gateway, HEC).
• Deep understanding of enterprise security: SAML 2.0, SSO, Active Directory integration, and MFA policies.
• Working knowledge of React to effectively collaborate with frontend engineers.

• English — Upper-Intermediate+

   

Nice to have:

• Experience with Protocol Buffers (Protobuf) for efficient data serialization.
• Knowledge of WebSocket-based communication for real-time applications.
• Familiarity with Duo Network Gateway and secure enterprise network infrastructure (DMZ architectures).

• Experience with Cisco AnyConnect NVM or Endpoint Security Analytics.

   

🎁 What We Offer:

• Remote-friendly, full-time role with flexible working hours
• Supportive and professional team
• A modern work environment with opportunities for growth
• Involvement in large-scale and innovative outstaffing projects
