About You You are an exceptional builder who wants outsized responsibility and impact, and have a demonstrated history of thoughtful and pragmatic decision making. You have designed, built, and maintained backend systems that delivered on complex problems with simple and robust code. You love tackling novel challenges, you are adept at finding third party tools that meet our needs, and can both quickly make something work and design it to scale and handle edge cases. You’re genuinely passionate about building, and are excited to be an integral part of a team of like-minded folks. Responsibilities Build the core systems that deploy our machine learning capabilities both in training and production, build metrics systems for rapid iteration and introspection, and help improve the performance of both by using your judgement to optimize for evolving technical and product requirements. Drive technology and architectural choices for Additive’s core services that will enable us to rapidly build and iterate on user experiences that enable our customers to do their best work. Design and build the integration of ML inference, monitoring systems, Large Language Model (LLM) interactions, application layers, and tax-related business logic into our core systems. Build out database layers supporting business logic and applications within our systems and data integration strategy with external vendor APIs and interfaces. Collaborate with the rest of the team on effective CI/CD systems that helps us all move faster. Engage directly with accountants to understand their needs and how we can best build a product that they absolutely love. Be expected to operate with autonomy and judgement to deliver tremendous value while working with both technical and market constraints. Requirements 5+ years experience working on backend systems in a meaningful ownership role for what was built and why, ideally for systems with meaningful data or ML workloads. Experience with ML concepts and integrating ML inference and monitoring capabilities into business applications. Comfortable with Python, cloud providers such as GCP/AWS, container technologies (e.g. Docker, Kubernetes, serverless platforms), and database and storage layers (e.g. Postgres, SQL, S3/GCS, Redis).
