Senior Software Engineer

About the Role

Treeline is looking for a Senior Software Engineer to join our growing engineering team. This is a full-stack, generalist role with a backend lean, spanning web application development, data pipelines, AI and LLM systems, and infrastructure. You’ll own small to medium-sized projects end to end, with strong support from teammates and plenty of room to explore new ideas. For those interested, there are also opportunities to work directly with customers in a forward-deployed capacity for part of the time.

• Leverage emerging AI innovations to build intelligent solutions that enhance managed service provider (MSP) services and customer experiences

• Collaborate cross-functionally with partner MSPs and internal teams such as finance and support to prioritize high-impact products

• Experiment with and evaluate new technologies and frameworks while balancing stability, future-proofing, and total cost of ownership

• Champion best practices by improving code quality, driving standards, and fostering a culture of continuous learning and open communication

• Ensure the platform remains performant, reliable, and scalable as the company grows

• Enjoy owning projects end to end across distributed systems, data engineering, and infrastructure

• Value modern tooling and are excited to work with tools like Graphite, Linear, and Cursor while staying pragmatic about technology choices

• Prefer a low-meeting environment that emphasizes focused building time

• Take initiative, enjoy autonomy, and are comfortable experimenting and learning quickly

• Communicate openly and value a respectful, transparent, team-first culture

• Enjoy a hybrid office setup with regular in-person collaboration

• 5+ years of professional software engineering experience (strong candidates at other levels are also encouraged to apply)

• Experience building or working with distributed systems

• Proficiency in a backend language such as Python or Go

• Experience working with relational databases, particularly Postgres

• Competitive compensation and extremely competitive equity grants

• High-impact role with minimal red tape and real influence on product and technical direction

• Opportunity for growth in a fast-scaling company backed by top-tier investors

• Collaborative culture centered on learning, experimentation, and personal development
