Job description

At Energy Solutions Corp, the best Principal Software Engineer isn't the one who writes the most code but the one whose Node.js decisions age the gracefully. The deal favors the seasoned — 8 years earns $154,000 - $219,000, a contract arrangement, and a technology charter you'll actually own.

Key Responsibilities

• Automate build, test, and deployment pipelines for faster release cycles
• Read the Relationship Building stack traces others skim past, and trace bugs to their root
• Lead technical design reviews for principal technology initiatives
• Reach into legacy Mentoring modules and leave them cleaner than you found them
• Lead the PostgreSQL migration that finally retires Energy Solutions Corp's no-ego legacy stack

What You'll Bring

• Roughly 9+ years operating in a similar Principal Software Engineer position
• Familiarity with Energy Solutions Corp-scale workflows, or the appetite to reach them
• A point of view on Energy Solutions Corp's space, sharpened by your own reading
• The humility to revise strong opinions when the data argues back
• The composure to deliver bad news early and clearly
• Comfort with contract arrangements and the rhythms of a candidly-kind workplace
• Proven Jest results, ideally seasoned in Minneapolis, MN

Half the technology platforms in MN quietly depend on something Energy Solutions Corp built in Minneapolis with team-oriented care. Every Principal Software Engineer at Energy Solutions Corp owns an outcome, not just a checklist of tasks.

We value work-life balance, so expect $154,000 - $219,000, flexible hours, paid sabbaticals, and a supportive mentoring program.

The team in Minneapolis is interviewing on a rolling basis, so early applicants get noticed first.
