What are the responsibilities and job description for the Senior Software Engineer position at Spark?

About Spark Advisors

We're Spark, a mission-driven company helping independent Medicare brokers build the insurance business of their dreams. The vast majority of beneficiaries select benefits with the help of an independent broker, but technology and support for brokers is woefully antiquated. We provide workflows and services to help brokers achieve transformative growth.

In just five years, we've partnered with over 6,000 brokers and enrolled over 140,000 beneficiaries, making us the fastest-growing Medicare brokerage in the country. Brokers love us: during this period of intense growth, we've maintained an NPS of 91 and a client retention rate of 93%, and we've helped brokers grow on average >100% since partnering with us.

It's an exciting time to be at Spark. Our diverse, remote-first team comes from leading technology, healthcare, and insurance companies, and has grown from 70 to 90 in the last year. Most recently, we've raised a Series B from leading investors who share our ambition.

Join us: we're always on the lookout for sharp, talented, empathetic teammates.

Summary

In this role, you'll have the opportunity to directly impact the industry's evolution, working on the core of our platform: the agent's operating system. This system is not just a tool, but the foundation of our brokers' daily work.

As a senior member of the broker productivity squad on our engineering team, you'll work to ensure our technical platform continues to meet the needs of our rapidly growing customer base. This will involve maintenance of our industry-leading web based broker platform. It will also involve making architectural decisions to support the long-term health and viability of the platform. Your day-to-day responsibilities will be diverse and impactful. You'll engage in both frontend and backend development, collaborate with product and design teams to innovate new features, and work with other engineers to scale our solutions. Embracing a data-driven approach, you will play a crucial role in developing technology that not only meets current needs but also anticipates future challenges, ensuring Spark continues to deliver exceptional value and performance to our top brokers.

What you'll do

  • Work across Spark's full stack in JavaScript and Python to build and maintain Spark's agent and member-facing products
  • Meet regularly with product and design to provide constructive feedback on design mockups and product scope
  • Work closely with product to deeply understand the relationship between agents and Medicare beneficiaries, focusing on developing features that ultimately improve retiree outcomes
  • Identify and manage technical debt, while also building robust infrastructure and frameworks to support the scalability of our platform
  • Actively contribute to the tech team's development standards, promoting best practices and continual improvement, and the growth of other teammates

What we're looking for

  • 5 years of building user interfaces with modern Javascript technologies such as Vue or React
  • 5 years of experience building API-driven web apps with Python
  • A history of developing component libraries via modern Javascript frameworks
  • Experience working with component-based CSS frameworks like Tailwind CSS
  • Product intuition and a keen interest in how tech investments drive intended business outcomes
  • Comfort with ambiguity and the ability to thrive in fast-paced environments
  • Strong communication and project management skills
  • A collaborative nature and comfort working with team members across the company
  • A commitment to continuous learning and growth and comfort with giving and receiving constructive feedback

Nice to Have

  • A history of building web apps with the Django framework
  • Background with development tools like Docker, Git and Webpack

Our salary ranges are based on paying competitively for our company's size and industry, and are one part of the total compensation package that also includes equity, benefits, and other opportunities at Spark. In accordance with New York City, Colorado, California, and other applicable laws, Spark is required to provide a reasonable estimate of the compensation range for this role. Individual pay decisions are ultimately based on a number of factors, including qualifications for the role, experience level, skillset, geography, and balancing internal equity. A reasonable estimate of the current salary range is listed below. We expect most candidates to fall in the middle of the range. We also believe that your personal needs and preferences should be taken into consideration, so we allow some choice between equity and cash.

Base Salary

$170,000—$190,000 USD

Why you should join our team

By joining Spark, you will get in on the ground floor of a fast-moving, well-funded, and mission-driven startup where you will have a profound impact on the brokers and beneficiaries we serve. And you'll learn, grow, be challenged, and have fun with your team while doing it.

We strive to help you and your family thrive. We're committed to supporting your happiness, healthiness, and overall well-being by providing a comprehensive benefits program. In addition to your base salary, we also offer:

  • Equity compensation
  • Health care, including dental and vision through our PEO Sequoia
  • Flexible work location; co-working available
  • 401k
  • Paid Time Off
  • Monthly Remote Work Stipend (help cover costs of home-office needs)
  • Paid Parental Leave
  • Up to 12 weeks for birthing parents
  • Up to 8 weeks for non-birth parents
  • 11 paid holidays
  • 2 week sabbatical at 5 years of employment
  • Wellbeing Perks through SpringHealth, OneMedical, PerkSpot, and SoFi
