Job description

Aerostrat is a fast-growing B2B SaaS company building a complete maintenance planning solution for the aviation industry. Our core product, Aerros, enables our customers to plan all the maintenance on hundreds of aircraft in a matter of minutes. Our solution helps customers understand the cost and efficiency of their maintenance operations while giving them the confidence to make data-backed business decisions. Over the past ten years Aerostrat has achieved a customer base that includes some of the world's most well-known airlines and aircraft operators. Aerostrat's success to date has been driven by a lean team focused on transforming complex asks into an easy-to-use product.
About this role
As a Sr backend software engineer at Aerostrat, you'll play a critical role in expanding our infrastructure and APIs to ensure we can scale with our customers.
As a member of our small but growing engineering team, you'll need to be a self-motivated, high-impact and driven individual that goes out of your way to learn about and produce the best solutions for our customers. Because our team is so lean, you will have a real opportunity to contribute to the direction of the product and see your ideas make it into production on a regular basis.
In this role, you will...
  • Learn everything there is to know about aviation maintenance planning through our on-boarding process (so don't worry if you do not have any experience in this industry!)
  • Analyze tough customer problems and come up with great designs that you will turn into efficient backend solutions
  • Design, develop, and maintain scalable systems and well-tested features
  • Design and implement services that are reliable, high-quality, performant, and sustainable
  • Work with our business team to build great user stories and designs from (sometimes) ambiguous requirements or problems
  • Occasionally wear many hats due to our smaller team size, with opportunities to work on everything from design to deployments, or meeting with our customers to build integrations for them

This role is great for you if...
  • You have significant experience with C#/.NET and SQL Server databases
  • You have significant experience building and consuming REST APIs and microservices
  • You have significant experience building B2B cloud solutions on Azure or AWS
  • You love learning about and solving real customer problems
  • You care a lot about making an impact on the business since we have such a small team, you'll be shipping important features all the time
  • You are a self-starter who gets excited about learning and improving anything possible since we are still constantly developing many parts of our engineering stack
  • You have a positive attitude and communication style because we've learned that excellent written communication and attitude go a long way for a remote team

Qualifications
Minimum Qualifications
  • 5+ years of work experience in C#/.NET
  • 5+ years of work experience with SQL databases
  • 3+ years of work experience working on REST APIs
  • 3+ years of work experience working with Azure or AWS cloud projects
  • 3+ years of work experience building technical designs for other engineers

Preferred Qualifications
  • Aerospace maintenance experience or interest in the aerospace industry
  • Experience building B2B SaaS applications

Why Aerostrat
As an engineer at Aerostrat, you will be a critical part of our growth journey. You will have a direct impact on the continued success of our existing product and play a foundational role in the development and refinement of our product offerings. Aerostrat products are developed with direct feedback from our customer base, and as part of our team, you will have opportunities to work closely with customers and have a voice to shape the direction of our products. At Aerostrat we pride ourselves on our excellent work environment with a fully remote team and tools, flexible hours, and a strong focus on results - not how many hours you spend available on Slack. Working at Aerostrat will offer you an opportunity to solve real customer problems, foster a healthy work-life balance, and make a huge impact on a highly successful product used by many of the airlines behind your travel and the packages shipped to your doorstep.
$140,000 - $200,000 a year
Our benefits include...
  • Working remotely with flexible hours to remove commute times
  • Unlimited PTO and 11 holidays per year
  • Multiple health insurance options with the possibility of an HSA with employer contributions
  • 401k with matching
  • Flexperks to cover work from home expenses, cell phone, and internet.
  • Travel rewards with our corporate travel provider
  • Annual team retreats
Compensation...
  • Title: Sr Software Engineer
  • Salary: $140,000 - $200,000
  • Job Type: Full-time; Remote (Within 50 miles of Seattle, WA preferred)
  • Schedule: Monday - Friday; Normal business hours
