As a Senior Platform Engineer, you will be at the heart of Avant’s technical evolution. This isn’t a maintenance role; you will be a key player in designing and building the foundational data and machine learning platforms that power our products and analytics. You will tackle the dual challenge of scaling our core systems for the future while pioneering the practical application of Generative AI to create real business differentiation.
You will join a focused, agile team with significant autonomy and a mandate to innovate. If you are a curious, hands-on engineer who thrives on variety and wants to shape how a successful fintech scales its most critical capabilities, this is the opportunity for you.
What you’ll do at Avant
Build and Evolve Our Data Platform
Design and implement our next-generation orchestration layer, transforming it from a series of environment-specific instances into a unified, multi-tenant platform.
Develop full-stack internal applications (Python backends, React frontends) that empower teams with self-service UIs for ingestion, transformation, and delivery.
Enhance our MLOps platform to empower teams with self-service tools for the entire model lifecycle.
Evolve and expand our core data and analytics stack, working with technologies like Kafka, Databricks, Spark, dbt, and Kubernetes to make advanced capabilities accessible to everyone.
Collaborate closely with Data Engineering and Product teams to understand their needs, design robust solutions, and build the tools that accelerate their work.
Shape Our Approach to GenAI
Move beyond the hype and contribute to the practical adoption of GenAI, focusing on applications that deliver real business value.
Help define patterns and practices for building reliable, observable, and cost-effective GenAI systems in production.
Build safe and effective sandboxes for developers to experiment with new tools and features.
Why you’re a fit at Avant
Experience: 5+ years of experience in backend or platform engineering.
Technical Foundation: Strong backend development skills, experience building and deploying services in a cloud environment like AWS, and a solid understanding of infrastructure concepts. While our stack is Python-heavy, we value engineering principles over specific tool expertise.
Problem-Solving Mindset: You can operate at multiple levels of abstraction, from high-level system design to hands-on coding. You approach unfamiliar tools and patterns with excitement and a desire to learn.
Pragmatism and Agility: You are a practical thinker who can critically evaluate tools and ideas. You're comfortable building rapid prototypes and iterating on proofs-of-concept to find the best path forward.
- Clear Communicator: You can articulate complex technical ideas and proposals, fostering open and productive design discussions.
Bonus Nice to Haves
Experience with our core stack: Databricks, Spark, Kafka, Airflow, Temporal, or dbt.
Hands-on experience with Terraform and AWS services relevant to data platforms (e.g., S3, EKS, MSK, DMS, Glue).
Familiarity with data engineering concepts or the machine learning lifecycle (MLOps).
Personal projects or a demonstrated interest in exploring GenAI or other emerging technologies.
Why This Opportunity
Build, Don't Just Maintain: You'll be creating new capabilities and evolving our platform, not just keeping the lights on. From our orchestration revamp to GenAI initiatives, there's significant greenfield work.
Career Growth: This role offers significant growth potential. We encourage our senior engineers to grow into technical leaders, architects, and mentors as the team and platform evolve.
A Culture of Ownership: We foster a proactive engineering culture where you are empowered to identify and solve underlying problems, not just treat symptoms. You'll have significant autonomy and the opportunity to influence major platform decisions.
Balanced Environment: Our team enjoys a hybrid work schedule (3 days/week in our Chicago Loop office) and a very quiet on-call rotation. We foster learning through team R&D time and company-wide hackathons.
This role is based on our downtown Chicago Office, located in the Merchandise Mart. We highly value collaboration and our hybrid schedule (M, T, Th in-office) enables flexibility to balance work and individual priorities.
