About Avantos
Avantos is building the AI-native operating system for financial services — transforming fragmented data into a single, intelligent system that powers workflows, automation, and decision-making. We’re a product-led, fast-moving team at the intersection of AI, fintech, and modern infrastructure.
The Role
We’re looking for a Senior Data & Platform Engineer to build the data and core platform and infrastructure layer that powers our AI systems. This is not just about pipelines — it’s about creating the systems, tooling, and abstractions that enable engineers and AI workflows to move fast, safely, and reliably.
What You’ll Do
- Design and implement core backend systems and integrations that power the product.
- Design and build our data platform (orchestration, pipelines, developer workflows)
- Create scalable systems for data ingestion, transformation, and access
- Design data models and APIs that won’t collapse under growth.
- Make sane decisions about schemas, indexes, migrations, and performance.
- Own infrastructure for data + AI workloads (containers, orchestration, cloud services)
- Enable self-serve data workflows for engineering and product teams
- Improve observability, reliability, and performance across the data stack
- Support AI/ML systems (embeddings, vector data, model pipelines)
- Build tooling for document processing, metadata, and normalization
What We’re Looking For
- 7+ years in data engineering, platform engineering, or backend infrastructure
- A track record of shipping and owning production systems.
- Strong systems thinking (not just pipelines — platform mindset)
- Backend system design and API design
- Data modeling and relational databases
- Performance, reliability, and failure modes
- Proficiency in Golang, SQL, Terraform, AWS
- Comfort in a fast-moving startup environment
Bonus
- LLMs / RAG, vector search, fintech or regulated systems
- Have startup or early-stage experience.
Why Join
- Build the foundation layer of an AI-native product
- High ownership + direct impact
- Work where data, platform, and AI converge
The Fit You’re someone who doesn’t just move data — you build the systems that make data usable at scale.
Why work at Avantos AI
- Culture: “Massive influence” – employees directly shape client success and product roadmap. Strategic ownership of core enterprise clients. Work alongside founders, engineers, designers, and product leaders. Career acceleration into leadership roles.
- Remote/Hybrid: HQ in New York, NY (in-office for most roles). Some positions (e.g., Senior DevOps Engineer) are listed as fully remote. Hybrid options available for certain roles. Offices also in Novi Sad (Serbia), with team members in the UK and Brazil.
- Notable perks: Mission-driven impact redefining financial services through intelligent automation. Opportunity to work at the intersection of AI, enterprise software, and financial services. Competitive compensation and growth opportunities.
