The opportunity

We’re looking for a Senior Software Engineer to help us build and scale the products that power Kin’s insurance platform. As we continue to grow, we’re investing in strengthening our core systems while accelerating the delivery of new features that improve the homeowner experience.

In this role, you’ll tackle complex engineering challenges across our Ruby-based backend and Typescript front-end systems. You’ll collaborate closely with Product, QA, and cross-functional partners to ship high-quality features using Scrum methodologies. Beyond delivery, you’ll play a key role in elevating engineering standards — mentoring junior engineers, contributing to architectural decisions, and helping ensure our systems remain reliable, maintainable, and scalable.

Your responsibilities

Design, build, and maintain scalable backend services in Ruby, with occasional contributions in Python and Typescript

Develop and enhance front-end functionality using modern JavaScript frameworks and Typescript

Lead and contribute to architectural and design discussions that improve long-term system maintainability

Ship large, complex features from concept through deployment with high quality and strong testing practices

Participate actively in Scrum ceremonies including daily standups, sprint planning, and retrospectives

Collaborate cross-functionally with Product, QA, PMO, and other engineering teams to align technical solutions with business goals

Mentor junior engineers through pair programming, code reviews, and technical guidance

Advocate for thoughtful technical investments and clearly articulate trade-offs to stakeholders

Contribute to improving development workflows, tooling, and engineering best practices

Success in this role

In your first 6–12 months at Kin, success is less about checking boxes and more about the impact you create. You’ll use your skills and judgment to take ownership of meaningful work, improve how we operate, and help move Kin’s mission forward. Along the way, you’ll deliver outcomes that make a real difference for both Kinfolk and the homeowners we serve.

By the end of your first year, you should feel confident in your role, trusted as an owner, and proud of the progress you’ve helped make.

You’ve successfully shipped multiple complex features that deliver measurable value to customers or internal stakeholders

System reliability, performance, or maintainability has improved due to your architectural contributions

Junior engineers demonstrate growth and increased confidence due to your mentorship and guidance

Technical trade-offs are better understood across teams because of your clear communication and advocacy

What you’ll bring

Core Experience & Technical Skills

Demonstrated track record of shipping large, complex software projects in production environments

Fluency in Ruby and experience working with Python or Typescript

Experience with PostgreSQL or other relational databases

Experience contributing to architectural design and technical decision-making

Ability to articulate the value and trade-offs of technical investments

Experience mentoring engineers through code reviews, pairing, or informal leadership

Familiarity with modern JavaScript frameworks such as React, Vue, or Angular

Experience operating within Agile/Scrum development environments

Working Style & Environment

Comfortable in a fast-paced startup environment with evolving priorities

Ability to operate independently with limited technical guidance

Strong communication skills and cross-functional collaboration experience
