As a Senior Full-Stack Software Engineer (Next-Gen Applications), you will design, develop, and maintain software applications tailored to enhance our security solutions. Responsibilities include writing and optimizing code, implementing back-end systems, and contributing to the overall software development lifecycle. Collaboration with a cross-functional team to deliver high-quality solutions is expected.

• Architect and build end-to-end features

for a multi-tenant cloud application and companion mobile apps—owning design, implementation, testing, deployment, and observability.
- Define technical architecture

(services, data models, APIs) using modern tools (e.g.,

Go or Rust for backend services; React/TypeScript for web UI; REST APIs; Kubernetes for orchestration; CI/CD pipelines).
- Design and implement device integration layers

—including Bluetooth/BLE, IP-based communication, and other embedded system APIs to enable secure, real-time data exchange.
- Produce and maintain formal documentation:

SRS (Software Requirements Specification)—functional/non-functional requirements, constraints, acceptance criteria; TSD (Technical Specification Document)—architecture diagrams, sequence/data-flow, API contracts, deployment topology, security controls.
- Coordinate vendors and third-party suppliers:

plan deliverables, review design/documents, perform code reviews, enforce standards, and manage risks/dependencies across external teams.
- Deliver excellence:

own timelines, backlog health, and release readiness; drive test automation, performance profiling, and production reliability (SLOs/SLIs).
- Security and compliance:

implement application security best practices (authN/ authZ, secrets, encryption, secure coding) and ensure data protection and auditability.
- Data & performance:

optimize queries and storage, instrument telemetry, and tune responsiveness for interactive workflows and device communication.
- Cross-functional collaboration:

work with Product, Design, Finance Ops, Field Operations, and Client Care to translate business objectives into technical solutions; mentor engineers and uphold coding standards.

Qualifications

• 5+ years of professional software development with demonstrable full-stack ownership (frontend + backend + DevOps).
• Strong CS fundamentals (data structures, algorithms, distributed systems).
• Backend:

proficiency in Go or Rust (or equivalent like ) building

secure, scalable services; experience designing robust web APIs (REST, gRPC).
- Frontend:

React (preferred) or Angular/Vue; strong TypeScript/JavaScript, component architecture, accessibility, responsive design.
- Cloud & DevOps:

k8s, containers, CI/CD (GitHub Actions/Azure DevOps), infrastructure-as-code; experience with AWS/Azure/GCP.
- Documentation:

proven experience authoring SRS and technical specs/TSD to guide delivery and serve as audit trails.
- Vendor management:

track record coordinating external engineering teams with clear specs, SLAs, and quality gates.

Bonus Points for

• Mobile hybrid development: familiarity with cross-platform frameworks such as Flutter or React Native.
• Device integration: experience with Bluetooth/BLE protocols, embedded system APIs, or IoT/wearable device communication.
• SQL optimization and database internals awareness; event-driven architectures (Kafka/Event Hubs).
• Security certifications or practical experience with cloud security models.
• Experience in data analytics products, interactive dashboards, or BI workflows.

Additional Competencies

• Systems thinking with a strong sense of craftsmanship and documentation discipline.
• Pragmatic leadership—able to mentor, review, and raise the engineering bar while shipping iteratively.
• Clear communicator who can align vendors and internal stakeholders and defend architectural decisions with data.
• Versatile and adaptable—willing to pick up new tools and frameworks as needed; focused on solving problems rather than adhering to a single stack.
