Job Description

Here at Appian, our values of Intensity and Excellence define who we are. We set high standards and live up to them, ensuring that everything we do is done with care and quality. We approach every challenge with ambition and commitment, holding ourselves and each other accountable to achieve the best results. When you join Appian, you’ll be part of a passionate team dedicated to accomplishing hard things, together.

The goal of our Platform Engineering team is to make it easy for our service teams to build and run production systems. As an experienced engineer in Platform Engineering, you will be helping re-architect our platform to run on public, private, and hybrid clouds and to allow for frequent, predictable and high impact changes. You will ensure that our world-class infrastructure is always available, responsive, and capable of meeting the diverse needs of our customers.

As part of the team, you will be responsible for leading a small team whilst still being super technical and hands on, building the cloud infrastructure that powers the Appian platform. This isn’t your average software developer role. On the Platform Engineering team, you’ll learn about a wide range of technologies and tackle new challenges as you add features and functionality to the Appian cloud infrastructure.

Right now this role is focused on building features that enable network connectivity between our platform and external networks. This will likely change and evolve over time, so this will give you an idea of the type of work you will be doing when you start.

To be successful in this role, you need:

The ability to leverage knowledge of data structures, algorithms, and design patterns to write software in a cloud infrastructure environment, using tools such as: Python, Go, Java, Terraform, Pulumi, CI/CD pipelines, RDBMS, No-SQL DBs, etc.
Solid knowledge of AWS services like: EKS, EC2, Lambda, DynamoDB, VPC networking, and S3 (or equivalent cloud provider experience)
Familiarity with networking and security best practices in the cloud
Experience providing technical leadership to drive pragmatic solutions and dive into impactful design decisions
Experience coaching junior and senior engineers while championing best practices across your team
Fluency in reviewing architecture / designs from team members, identify problems, and make suggestions for better practices
Experience with conducting code reviews looking out for the elegant approach, performance, maintainability, and security
Ability to identify dependencies between multiple teams. Ability to communicate blockers and escalate as needed
Experience operating business-critical production services
Experience automating the creation and configuration of cloud resources and services on-demand
Interest in automating every aspect of our development lifecycle and help us in our mission to achieve continuous delivery
Share advanced/expert knowledge with others in the department, both on and off team; maintain a reputation as a key resource in those areas
Lead technological changes to keep the platform modern

Some of the tools and resources we will equip you with include:

Dedicated learning time to become an expert in technologies like Kubernetes, AWS, Docker, and Linux networking
Opportunities for growth and leadership
Engineering Indie Time (dedicated time to build whatever you want) and annual hackathons - we value activities that inspire others and get creativity flowing!

Basic Qualifications:

10-15+ years experience designing, building and architecting software in an enterprise software or SaaS/PaaS environment
Some leadership experience (managing and mentoring a small team of Junior Developers)
Advanced knowledge of at least one programming language and comfortable working with Object-Oriented programming concepts
