Job description

Array is a financial innovation platform that helps digital brands, financial institutions, and fintechs get compelling consumer products to market faster. We deliver a suite of credit and identity monitoring tools, privacy protection, and a financial ads marketplace via embeddable widgets or a clean, modern API. Our private label offerings help drive revenue and increase engagement for our customers while empowering millions of consumers to achieve their financial goals.
As a remote-first company, we're focused on providing opportunities for high performing individuals to have deep impact in the fast growing fintech space. A clear mission, a commitment to continuous improvement and a willingness to experiment empower us individually and together deliver the best products for our clients and users.
The Senior Software Engineer at Array will bring foundational knowledge in software engineering and lead our engineering teams to solve the biggest problems and challenges that we're facing. This position will report to an Engineering Manager and work in a squad that owns one of our product sets.
This role will start as a contract role for a 180 probationary period before converting full time.
This role is fully remote; however, we are prioritizing candidates located in Chicago, IL due to strong alignment with the technical talent market (Go developers) for this role.
You Will:
  • Join an engineering organization filled with sharp engineers with a track record of building products used by millions.
  • Work with a squad of engineers to build secure, high-scale cloud applications using Go, Node.js, and other modern languages.
  • Use modern tooling including the latest AI to think, build, and ship faster with less toil.
  • Help ensure the reliability and availability of the systems you build, including participating in an on-call rotation with your squad.
  • Conceptualize and deliver software solutions with support and guidance from our Principal Engineers and Engineering Managers.
  • Be an emerging expert in RESTful APIs, microservices, cloud technologies, and databases.
  • Spend the majority of your time building solutions rather than talking about them.

You Have:
  • 6+ years of professional software development experience in Go, C#, or Java in a fast-paced environment (like a startup).
  • 4+ years experience building and scaling a revenue generating product.
  • 2+ years experience running production applications in AWS, Azure, or GCP with a broad understanding of building for cloud scale and securing internet-facing applications with high value data.
  • A forward-looking approach to using Generative AI (like Cursor, Claude Code, and custom LLM agents) to accelerate delivery, reduce toil, and prototype solutions.
  • Experience with containerization tools like Docker and Kubernetes.
  • Experience with relational and document databases like Postgres, SQL Server, and MongoDB.

Pay Transparency: $80-$100/hr for the 180 day period.
Expected interviews: Recruiter conversation - Technical Interview - Loop: Engineering Leadership Interview, How We Work Interview.
Array Offers All Full Time Employees the following Benefits and Perks:
  • Full medical, dental, and vision, premiums covered at 100% for full-time employees and 70% for dependents
  • Unlimited PTO and sick leave + 14 company holidays to encourage a healthy work-life blend
  • 100% 401k match up to 4% with immediate vesting
  • Generous and competitive parental leave for all parents
  • $1,000 desk setup subsidy to set-up your unique remote office
  • $100/month to subsidize wifi/cell phone expenses
  • Summer Fridays (half-day Fridays) typically from late May to the end of August
  • Arrayaversary Kits for work anniversaries
  • Commuter benefits for those who choose to go into our New York City or San Francisco office spaces
