Mid - Level Full Stack Developer

We are seeking a hands-on Mid-Level Full Stack Developer with 7-10 years of software engineering experience to design, develop, test, deploy, and support scalable cloud-connected applications. The successful candidate will contribute across backend services, React-based web applications, databases, APIs, cloud infrastructure, real-time data pipelines, and production troubleshooting, while working closely with senior engineers and cross-functional teams.

The role will support highly available digital platforms for remote supervision, configuration, health monitoring, control, telemetry, and event-driven alerting across connected field devices and gateways. Solutions must enable secure, low-latency interaction between cloud applications and IoT / edge systems used in fire, life-safety, paging, and emergency communication environments, where reliability, traceability, resilience, and security are important.

The candidate will have responsibilities across the following functions:

Engineering Delivery and Ownership:

• Develop assigned features and services from requirements through implementation, testing, deployment, production support, and continuous improvement.
• Participate actively in design discussions, sprint planning, code reviews, defect resolution, and technical documentation while taking end-to-end ownership of assigned modules.
• Work independently on moderately complex technical problems, escalate risks early, and collaborate with senior engineers on architecture, quality, security, and performance decisions.
• Document implementation details, interfaces, deployment steps, troubleshooting guidance, and key technical decisions to support team knowledge sharing and redundancy.

Full Stack Architecture and Development:

• Develop scalable backend services primarily using Python and Golang, with well-defined RESTful APIs and clear microservices boundaries.
• Build and maintain React.js web applications using reusable components and modern state-management patterns such as Hooks and Redux where appropriate.
• Design and optimise PostgreSQL data models, schemas, indexes, and queries; troubleshoot data-integrity, concurrency, and database-performance issues.
• Implement secure authentication and authorisation using OAuth / JWT, role-based access control, secrets management, and secure service-to-service communication patterns.

Connected Devices, Real-Time Data and IoT Integration:

• Develop application flows for connected field devices, edge gateways, and cloud services, including device discovery, provisioning, configuration, heartbeat/health monitoring, telemetry, command-and-control, and event handling.
• Implement and support real-time and event-driven communication using MQTT, REST APIs, Kafka, WebSockets and, where applicable, SIP / WebRTC or related communication technologies.
• Build reliable message-handling logic for intermittent networks and field conditions, including reconnect behaviour, retries, idempotency, duplicate handling, buffering, and fault recovery.
• Collaborate with embedded, firmware, test, and product teams to integrate device protocols, APIs, telemetry streams, alarms, and status information into unified web and cloud applications.

Cloud, Containers and Data Platforms:

• Develop and deploy applications on AWS using services such as EC2 S3 RDS and other appropriate managed services, following established scalability, availability and security practices.
• Containerise services using Docker and contribute to cloud-native deployment patterns, environment configuration, and controlled releases.
• Contribute to CI/CD pipelines, automated build/test/deploy practices, configuration management, and repeatable production deployments.
• Develop and support streaming and asynchronous pipelines using Apache Kafka and related messaging technologies; exposure to Hadoop / large-scale data processing is advantageous.

Reliability, Security, Quality and Production Support:

• Develop applications with appropriate resilience patterns, including health checks, graceful degradation, retries, recovery mechanisms, and defensive error handling.
• Implement structured logging, monitoring, metrics, tracing, and alerting to support rapid issue detection and root-cause analysis.
• Write unit, integration, API, regression, performance, and security tests as applicable; maintain clear technical documentation and participate constructively in code reviews.
• Troubleshoot issues across browser / UI, API, service, database, message pipeline, cloud infrastructure, and connected-device layers, working with other teams where required.

Stakeholder and Cross-Functional Collaboration:

• Work closely with Potter US Engineering, Product Management, UX, DevOps, SDET, embedded / firmware, hardware, manufacturing, and other stakeholders to translate requirements into robust software solutions.
• Communicate technical status, risks, trade-offs, defects, and support findings clearly to senior engineers and cross-functional teams.

Key Success Measures:

• Consistent delivery of secure, production-ready full-stack features against committed scope, quality, schedule, and performance expectations.
• Reliable operation of cloud-connected applications and real-time device data flows, with effective diagnostics and timely recovery from failures.
• Strong hands-on contribution in Python / Go backend services, React applications, PostgreSQL, APIs, AWS deployment, and production troubleshooting.
• Measurable improvement in engineering quality through automated testing, code reviews, CI/CD practices, security controls, observability, reusable components, and clear documentation.
• Increasing technical independence, broader ownership across the stack, and effective knowledge sharing within the engineering team.

Requirements:

• 7-10 years of professional software development experience with meaningful hands-on responsibility across full stack, backend, cloud, APIs, databases, and distributed systems.
• Bachelor's degree in Computer Science, Information Technology, Electronics, or a related engineering discipline; M. Tech / MCA or equivalent advanced qualification is an advantage.
• Demonstrated ability to independently design and deliver moderately complex software features while collaborating effectively with senior engineers, reviewers, and cross-functional teams.
• Experience developing scalable, secure, production-grade applications and services, preferably for connected products, industrial systems, IoT, and real-time monitoring domains.
• Strong communication, analytical reasoning, ownership, collaboration, and problem-solving skills.

Tech Stack and Tools:

• Python backend development
• Golang for microservices / performance-sensitive services
• React.js
• RESTful API design and implementation
• Microservices architecture
• Database schema design and query optimisation
• AWS (including EC2 S3 RDS)
• Docker/containerization
• Security: authentication/authorisation using OAuth, JWT, RBAC or equivalent patterns.
• PostgreSQL.
