Why this role exists

Our edge is spotting the biggest business lever, choosing the leanest technical path, and shipping without drama. Senior Engineers translate product goals into smart trade-offs, keep momentum high, and make the whole team faster—not just write more code.

What you’ll do

• Shape the plan. Break ambiguous product ideas into sprint-sized work that balances effort, impact, and risk.
• Review for leverage, not lint. Run architecture and code reviews that surface material issues and unblock teammates the same day—no nit-picking that slows delivery without adding value.
• Jump to the critical path. Whether it’s UI, API, data, or infrastructure scripts, pitch in wherever progress stalls.
• Steer incident response. Coordinate fixes, keep customers informed, and capture learnings in concise post-mortems.
• Pair and communicate. Debug side-by-side, share context freely, and write crisp updates so everyone moves in the same direction.
• Challenge defaults. Question “how we’ve always done it,” ignore sunk costs, and choose solutions that best serve today’s goals—even if that means rewriting or deleting code.
• Build and ship. Design, develop, and deploy scalable microservices and front-end features using Python (FastAPI/Flask), React, AWS, PostgreSQL, DynamoDB, and search technologies like ElasticSearch.
• Champion infrastructure as code. Use CDK, CloudFormation, or Pulumi to keep environments reproducible and secure.
• Mentor and multiply. Share knowledge, guide engineers toward better decisions, and raise the technical bar across the team.

How we’ll measure success

• Projects you lead hit agreed release dates despite shifting requirements.
• Trade-off thinking is evident in design docs, review comments, and sprint planning.
• Change-failure rate on services you touch stays under 5 percent, with rapid recovery when issues surface.
• Teammates say you clarify priorities, remove blockers, and make their work easier—especially through focused, high-value reviews.

Qualifications

• 4+ years of professional experience building and operating production web applications with Python; FastAPI or Flask preferred.
• Solid experience designing and implementing microservice architectures and event-driven systems.
• Strong working knowledge of AWS (e.g., ECS/EKS, Lambda, SQS/SNS, DynamoDB, RDS, CloudWatch).
• Proficient in SQL and NoSQL database design, optimization, and maintenance. Familiarity with ElasticSearch is a plus but not required at an expert level.
• Comfortable with modern front-end development using React.
• Hands-on experience with Infrastructure-as-Code tools such as CloudFormation, CDK, or Pulumi.
• Demonstrated success operating in fast-moving startup environments characterized by ambiguity and frequent pivots.
• Interest in AI-assisted development tools (e.g., Cursor, Devin AI) and a habit of integrating them into daily workflow.
• Excellent communication skills and a track record of mentoring peers.

Desired attributes

• Prior startup experience or proven comfort with rapid change.
• Ability to balance delivery speed with engineering rigor and maintainability.
• Highly autonomous, with a proactive, customer-centric mindset.
