Senior Software Engineer, C# / .NET
Wildbit
Wildbit is the team behind Postmark, Beanstalk, DMARC Digests, and People-First Jobs. We’re self-funded, profitable, and have been working remotely since 2000. We believe that businesses are human, and our team is committed to proving you can grow a profitable company while prioritizing people first. We exist to support our team, and our values and products reflect the care and intention that we operate with. You would be joining a team of ~30 people, where you will initially be spending your time becoming an expert on the Postmark product.
Our technology
Postmark is Wildbit's largest product, a distributed email-as-a-service system that is capable of processing 1000+ emails per second. Over the last year, we've been working in earnest to migrate all of Postmark's systems into AWS, and with that work complete, we're now turning an eye towards scalability and operability. Our cloud-native environment is currently a blend of .NET Core running in Linux containers, or as Lambdas, with a handful of remaining Windows-based services we're in the process of refactoring. That said, this role will focus primarily on C#/.NET, but you will also interacting with other tools and infrastructure like Elasticsearch, Grafana, Kibana, MySQL, and various AWS services (eg. RDS, ECS, Cloudwatch, etc.). Because Wildbit is product-agnostic, there will be opportunities to branch out and work on other products in the future, not all of which are written in C#.
Our engineering team
Engineers at Wildbit are given a tremendous amount of autonomy to guide the technical direction of our products, but with great power comes great responsibility. 🕷️🕸️ The team holds themselves to a high standard for the reliability, maintainability, and usability of code they write and the systems they design — all in service of creating the best possible experience for customers. As such, engineers are encouraged to be product-minded, considering extensible design patterns to enable building the best solution for today, while planning ahead for future growth.
About you
You will be a great fit for this role if you have a strong technical point of view that is coupled with pragmatism and an ability to execute. We're a remote-first team that believes in the value of 'deep work,' so you should be very comfortable with written forms of communication. We respect and care deeply about each other as individuals, so though we are seeking a self-motivated teammate, we're also looking for someone who will support and encourage others to do their best work.
Ideally you will have:
- Played a significant role in designing, building, and operating complex production systems with components of varying scalability, reliability, and performance requirements
- Experience with managed cloud infrastructure (eg. AWS, GCP, Azure, etc.) and system automation tools
- Passion for guiding systems and software towards improved standards and practices. (We're big fans of Twelve-Factor App.)
- Familiarity with various deployment architecture paradigms, such as zero downtime deploys, canary servers, etc.
- (Nice to have) Familiarity with email-specific topics, such as SMTP, SPF, DKIM, DMARC, etc.
What you will be responsible for
- Designing and implementing software that strikes the right balance between delivering on business needs and delivering the quality of code you are proud to ship
- Shaping the Postmark system over time to remain highly reliable and scalable, through system design, infrastructure improvements, code optimizations, or other technical initiatives
- Guarding the health of our systems — you’ll be part of an on-call schedule and help mitigate system abuse by spammers
- Setting clear expectations around your work, knowing when to break down nebulous tasks into manageable parts, and communicating that to your teammates
- Being a steward for developer standards, best practices, and quality
- Being a partner to Customer Support, Product, and Design, and collaborating with those teams cross-functionally
What are we looking for
- Someone with the ability to look at problems objectively before coming up with solutions - As a small team, we are constantly having to take into account a number of possible non-functional factors when designing software, eg. complexity of work, impact to customers, monetary cost, business urgency, etc. Considering these factors is a key part of informing our team goal setting and prioritization process.
- Someone with the ability to approach work interactions with kindness - Our team is a group of people who carry a lot of respect and trust for one another, which is rooted in kindness. Kindness is constructive and candid (and perhaps not always 'nice'), and implies a genuine desire to see others succeed. (Here is somebackgroundreading if you are unfamiliar with this concept.)
- Someone who thrives on digging into complex systems to make them less complex - Postmark is a product that has been around for a decade, so it should come as no surprise that there are certain areas of the system that are less known and less robust than others. We are steadily addressing these areas as the need arises, and are bringing them into more modern design patterns and tooling.
