Role Description

Energiot is seeking a proactive and highly autonomous Mid Software Engineer to join our growing product and R&D team in Barcelona. The role focuses on the development of the cloud software and web platform that powers our IoT ecosystem for electrical grid monitoring and smart energy applications. You will work across the full stack, from backend services and APIs to web frontends, building the systems that ingest, process, and visualize sensitive data about the real-time status of electrical grid lines.

Because the platform handles critical grid data, security and reliability are central to everything you build. This is a high-ownership role: your decisions and actions will carry significant weight, so we are looking for someone who thrives with autonomy and is comfortable driving features end to end in a multidisciplinary environment combining software, IoT platforms, and real-world sensor data.

Key Responsibilities

Design, develop, and maintain full-stack features for our SaaS platform, with a strong focus on frontend development using React and TypeScript.
Build and maintain backend services and REST APIs in Node.js / Python.
Design and operate cloud infrastructure and services on AWS, following best practices for scalability and security.
Apply secure coding and cybersecurity practices throughout the platform, ensuring the confidentiality and integrity of sensitive grid data.
Integrate with and extend our IoT cloud platform (ThingsBoard), including dashboards, rule chains, and device management.
Contribute to the full development lifecycle: requirements analysis, technical design, implementation, testing, and deployment.
Diagnose and resolve production issues, contributing to the reliability and observability of the platform.
Collaborate closely with firmware, hardware, and product teams.

Qualifications

Essential:

Bachelor's or Master's degree in Computer Science, Telecommunication Engineering, or a related field.
Minimum 2–3 years of experience in software development.
Strong programming skills in JavaScript/TypeScript and React.
Experience developing and consuming REST APIs and backend services.
Solid hands-on experience with AWS and cloud-based SaaS architectures.
Strong cybersecurity awareness and experience applying secure development practices, particularly when handling sensitive or critical data.
Experience managing agentic development workflows, effectively leveraging AI coding agents to build, review, and ship software with autonomy and sound judgment.
Fluency in Spanish and English.
Proactive and highly autonomous mindset, comfortable taking ownership and making impactful technical decisions with minimal supervision.

Preferred / Nice to Have:

Knowledge of SCADA communication protocols, particularly TASE.2 (ICCP / IEC 60870-6) and IEC 60870-5-104 (IEC 104).
Experience with IoT cloud platforms, particularly ThingsBoard.
Experience handling time-series data or device telemetry at scale.
Experience with public cryptography and secure channels
Experience with Docker and containerized deployments.
Familiarity with CI/CD pipelines.
Experience using API testing tools such as Postman.
Interest in the energy sector and sustainability.

What We Offer

Full-time, permanent contract
Entrepreneurial startup culture with a high level of ownership
Private medical insurance coverage (Adeslas PYME total)
Office located in Barcelona, with a strong focus on innovation and sustainability.
