Candidates with strong hands-on HES/MDM, AMI, DLMS/COSEM, IoT, or utility software experience may be considered even with a different academic background.
Essential Duties and Responsibilities:
• Build new automations in Python: API integrations, data pipelines, scheduled jobs, and process replacements scoped with operating partners.
• Maintain the existing Power Automate estate, both unattended cloud and desktop flows. Triage failures, repair flows, and keep unattended runs healthy on the bot-server farm. Operate the Power Platform space around them: environments, solutions, connection references, and pipeline-managed deployments.
• Migrate Power Automate flows to Python where the economics favor it. Retire flows rather than patching them indefinitely.
• Integrate systems over REST APIs. Handle JSON and XML transformation, authentication (OAuth, service principals), and error handling that survives flaky endpoints.
• Author SQL queries, tables, and stored procedures that support automations.
• Operate what you build. Instrument jobs with logging, monitoring, and alerting so failures surface before the business notices them. Write runbooks.
• Improve how automations run. Today they run as scheduled jobs on VMs. Help evaluate and move toward containerized or Azure-native execution (Functions, Container Apps) where it reduces operational load.
• Use AI coding tools as a core part of daily development, within company governance and review standards.
• Document what you build so the next engineer, or an operating partner, can understand and extend it.
Knowledge, Skills and Abilities:
• Python proficiency: clean scripting, packaging, error handling, structured logging, and enough testing to trust a job running unattended at 2 a.m.
• Power Automate strength across cloud and desktop flows: able to read, debug, and repair complex unattended flows built by someone else, plus the platform administration around them. You do not need to love the platform. You do need to support it capably, including solo coverage when other developers are out.
• REST API integration experience, including authentication patterns and rate-limit handling.
• SQL Server competence: comfortable writing T-SQL and authoring queries, tables, and stored procedures through a reviewed, versioned release process.
• Working knowledge of Azure: DevOps pipelines at minimum; Functions, Container Apps, or AKS exposure a plus.
• Daily fluency with AI-assisted development. You should be able to describe, in concrete detail, how you structure work with an agentic coding tool: what you delegate, what you review, where it fails, and how you catch it.
• PowerShell and shell scripting for glue work on Windows and Linux hosts.
• Production instincts: idempotent jobs, retries with backoff, alerting thresholds that page on real problems and stay quiet otherwise.
• Plain written and verbal communication. You will work directly with non-technical process owners who need to understand what an automation does and what to do when it stops.
Training and Experience:
• 3 to 5 years in automation engineering, RPA, or software engineering roles with automations shipped to production and operated afterward.
• A track record you can walk through: what you built, what broke, and what you changed.
• Demonstrated, current use of AI coding tools in real work. Candidates will be asked to describe their workflow in specifics; vague answers end the conversation.
Key Responsibilities :
a) Plan and execute preventive, predictive, and breakdown maintenance of production machines and utilities.
b) Ensure maximum machine uptime and minimize production downtime.
c) Troubleshoot and resolve mechanical, electrical, pneumatic, and hydraulic issues.
d) Prepare and implement preventive maintenance schedules.
e) Monitor machine performance and recommend improvements for higher efficiency.
f) Maintain maintenance records, breakdown reports, and spare parts inventory.
g) Coordinate with production, quality, and stores departments for smooth operations.
h) Lead and supervise the maintenance team while ensuring adherence to safety practices.
j) Support TPM, 5S, Kaizen, and continuous improvement initiatives.
k) Ensure compliance with ISO 9001:2015 and IATF 16949:2016 requirements.
Skills Required:
a) Strong knowledge of preventive and breakdown maintenance.
b) Hands-on experience with manufacturing equipment and utilities.
c) Basic knowledge of PLCs, sensors, motors, and industrial automation.
d) Good troubleshooting and root cause analysis skills.
e) Knowledge of TPM, 5S, and maintenance planning.
f) Good communication, leadership, and team management skills.
