Founding Lead Engineer / Principal Systems Architect

Who We Are

We exist to unlock human potential.

Too often, AI drains it—drains budgets, drains energy resources, drains ownership of data. OpenTeams was founded to change that. We build AI that empowers. Our models are energy-efficient, cost-effective, and fully yours. 

Our ethos is open source. That means freedom, trust, and accountability are built into every line of code. We reinvest 3% of our profits back into the open-source community, because we believe tech is most powerful when it serves everyone.

At our core, we value freedom, teamwork, accountability, and uncompromising quality. If you want to challenge the status quo, and shape tools that set people free, OpenTeams is the place to do it.

Founding Lead Engineer / Principal Systems Architect

Evidence-Governed AI/Data Platform

Location: Remote / Hybrid
Employment Type: Full-time
Seniority: Principal / Staff-level
Experience: 8-12+ years preferred, or equivalent exceptional experience

About the Role

We are building a confidential intelligent operations platform for evidence-governed analysis, operational reconstruction, model-assisted workflows, and high-integrity reporting in regulated domains. The first deployment focuses on healthcare integrity, provider-level identity mapping, licensing, ownership, source reconciliation, and defensible review workflows.

We are seeking a hands-on Founding Lead Engineer / Principal Systems Architect to work directly with the concept architect and translate a large, complex system vision into production-grade software, data architecture, model integrations, validation harnesses, and secure Kubernetes-based deployment infrastructure.

This is not a standard software engineering role. This is a founding technical role for building the core architecture of a serious AI/data platform from the ground up. The right candidate must be able to absorb abstract system concepts in real time and convert them into schemas, APIs, service boundaries, deployment artifacts, validation tests, and pragmatic engineering roadmaps.

What You Will Build

You will lay the technical foundation for a modular, enterprise-scale AI/data platform, including:

• canonical identity and entity-resolution services;
• source registry and evidence-management services;
• provider-level healthcare integrity workflows;
• relational, graph, object-store, retrieval, and audit data layers;
• deterministic rules and validation services;
• model-adapter and multi-model routing layers;
• structured-output and model-evaluation workflows;
• human-in-the-loop review workflows;
• graph, timeline, and evidence-review prototypes;
• evidence-linked reporting;
• audit logging and compliance-supporting records;
• secure Kubernetes / cloud / private-infrastructure deployment;
• validation, benchmark, and regression harnesses.

The first deployment will focus on provider-level healthcare integrity. Future deployments may extend into other regulated and high-consequence domains, including legal, financial, AI governance, cyber, public-sector, operational risk, and training/simulation environments.

Key Responsibilities

Concept-to-Code Translation

• Work side-by-side with the concept architect to convert advanced system ideas into technical specifications, service maps, data models, APIs, schemas, tests, and deployment plans.
• Translate verbal and written design guidance into architecture diagrams, implementation backlogs, acceptance criteria, and working prototypes.
• Identify ambiguity, missing assumptions, engineering risks, security issues, and implementation conflicts.
• Help turn an evolving concept architecture into reproducible, testable, maintainable software.

Backend and Platform Engineering

• Build production-grade Python services, APIs, data pipelines, background workers, and orchestration logic.
• Design clean service boundaries for ingestion, entity resolution, evidence management, review workflows, reporting, audit logging, and model integration.
• Build deterministic, auditable workflows for high-consequence system operations.
• Establish repository structure, coding standards, documentation practices, testing standards, and implementation discipline.

Data, Graph, and Knowledge Architecture

• Design and implement relational schemas, graph models, object-storage structures, retrieval indexes, and audit records.
• Build canonical identity and entity-linking systems that reconcile conflicting real-world records.
• Support relationship topology, ownership mapping, provider-network analysis, and source-conflict preservation.
• Implement data validation, source normalization, evidence linking, deduplication, and data-quality checks.

AI / LLM Systems Engineering

• Build a model-agnostic adapter layer for open-weight and hosted models.
• Implement multi-model routing for parsing, extraction, summarization, evidence explanation, report drafting, reviewer critique, and deterministic no-model workflows.
• Integrate model-serving infrastructure such as vLLM, KServe, Ray Serve, Ollama, llama.cpp, Hugging Face, or equivalent tools where appropriate.
• Implement structured outputs, prompt/template management, model-call audit, output validation, and model versioning.
• Ensure model outputs remain constrained by evidence, rules, schemas, human review, and audit records.

Human-in-the-Loop Review and Visualization

• Build rapid internal UI prototypes for evidence review, graph visualization, timeline inspection, review queues, report review, and audit inspection.
• Use tools such as Streamlit, Plotly Dash, Retool, React, Next.js, or equivalent frameworks where appropriate.
• Design backend APIs and data contracts that allow a dedicated frontend or full-stack engineer to later build a production analyst/reviewer workspace.
• Ensure human reviewers can inspect evidence, source conflicts, model outputs, rule triggers, and report language before high-consequence outputs are finalized.

Infrastructure, DevSecOps, and Deployment

• Deploy services using Docker, Kubernetes, Helm, GitOps, CI/CD, RBAC, secrets management, observability, and secure environment practices.
• Support cloud, private-cloud, hybrid, or OpenTeams/Nebari-aligned infrastructure where applicable.
• Implement secure configuration, environment promotion, logging, backup/restore, and infrastructure-as-code practices.
• Build deployment patterns that can support development, test, staging, and controlled pilot environments.

Validation, Evaluation, and Benchmarking

• Build synthetic datasets, golden tests, regression tests, benchmark suites, schema tests, model-output checks, and security-boundary tests.
• Validate ingestion throughput, entity-resolution accuracy, graph query performance, model latency, report generation, audit volume, and backup/restore behavior.
• Ensure every major module has clear acceptance criteria and reproducible test evidence.

Required Qualifications

• 8+ years of professional software engineering experience, or equivalent exceptional experience.
• Expert-level Python engineering.
• Experience building production backend services, APIs, data pipelines, and distributed systems.
• Strong SQL and relational database design experience, preferably PostgreSQL.
• Experience with graph databases, knowledge graphs, or complex relationship modeling.
• Experience with LLM integration, open-weight models, structured outputs, prompt/template management, or model-evaluation workflows.

• Experience with data validation, audit logging, RBAC, secrets management, and secure software design.
• Ability to design modular systems from ambiguous early-stage architecture.
• Ability to translate non-engineering conceptual guidance into concrete software architecture and implementation plans.
• Strong written documentation skills.
• Comfort working directly with a non-engineer concept architect.

Strongly Preferred Qualifications

• Experience with Nebari, Dask Gateway, Keycloak, or comparable data-platform infrastructure.
• Experience with vLLM, KServe, Ray Serve, Ollama, llama.cpp, Hugging Face Transformers, or comparable model-serving infrastructure.
• Experience with Neo4j, Cypher, graph analytics, graph ETL, or graph visualization.
• Experience with OPA/Rego, policy-as-code, deterministic rule engines, symbolic validation, or explainable decision logic.
• Experience with FastAPI, Pydantic, SQLAlchemy, Alembic, pytest, and modern Python service design.
• Experience with Terraform, ArgoCD, Flux, Vault, Prometheus, Grafana, OpenTelemetry, or comparable DevSecOps tooling.
• Experience with vector databases, hybrid retrieval, pgvector, OpenSearch, Elasticsearch, or comparable retrieval systems.
• Experience with Dask, Spark, Kafka, Redpanda, RabbitMQ, or comparable distributed processing and event-streaming systems.
• Experience in healthcare, government, legal, finance, cybersecurity, program integrity, or other regulated environments.
• Familiarity with provider enrollment, NPI/NPPES, PECOS, LEIE/exclusion references, licensing records, corporate registries, or healthcare integrity workflows.
• Familiarity with EDI healthcare transactions, eligibility files, managed-care encounters, FHIR, HL7, or EHR audit logs is helpful for later expansion phases.
• Experience building AI systems with human review, auditability, evidence controls, and high-consequence output safeguards.
