📋 Description

• Build with impact: Architect and deliver end-to-end systems, from internal automation to customer-facing portals, ensuring they are scalable, fast, and user-friendly. • Own the platform: Improve and extend core platforms and developer tooling, making it easier for teams to build, test, and ship quality software. • Drive innovation: Rapidly prototype and iterate on new workflows and product ideas that expand our offering and improve the broker and customer journey. • Partner cross-functionally: Collaborate with Product Managers, Designers, and other Engineers to scope, design, and deliver high-impact solutions. • Raise the bar: Lead by example through code reviews, mentorship, and championing engineering best practices across the team.

🎯 Requirements

• Track record in fast-paced environments: Experience as a Senior or Staff Engineer in a high-growth startup or scale-up, with a strong bias toward shipping. • System design at scale: Proven ability to design and build complex systems that power both back-end automation and front-end experiences. • Modern tech expertise: Deep experience with Python, Node.js, and AWS serverless architecture (e.g., Lambda, API Gateway, DynamoDB). • Front-end capabilities: Skilled in developing responsive, performant front-ends using modern JavaScript frameworks such as React. • Product-minded mindset: Experience working closely with product and design teams to solve user problems, not just deliver features. • Can deal with ambiguity: Comfortable navigating changing priorities and incomplete information to make strong technical decisions. • Desirable: Exposure to the energy sector or other regulated industries. • Experience building internal tools or platforms for brokers, sales teams, or support agents. • Familiarity with real-time data processing or agentic/AI-driven systems.
