About DatalignDatalign Advisory is a Cambridge-based fintech building the comprehensive AI-native platform for how Americans find, evaluate, and work with financial advisors — and how advisors grow. Our platform spans five products: curated lead generation, GEOsAI geographic intelligence, RelationshipAI prospect insights, Halo consumer engagement, and a customizable agentic AI layer for advisory firms.
Most companies in this space pick one lane — they’re a matching platform, or a CRM enrichment vendor, or a scheduling tool. We’re building the integrated infrastructure layer underneath all of it, powered by a proprietary knowledge graph of 200M+ Americans.
We’ve served 100,000+ consumers, referred $80B+ in assets to 13,000+ advisors, won Financial Advisory Platform of the Year at the 2026 FinTech Breakthrough Awards, and recently opened our compliance-by-design agentic AI platform to advisory firms across the industry. We’re small, we move fast, and the problem space is genuinely hard.Please note: We are only accepting applications from candidates in the Greater Boston area, as this is a hybrid role with 4 days a week in office.
The RoleWe're looking for Senior Software Engineers with deep AI/ML expertise to join a small, high-impact engineering team. This is a hands-on technical leadership role. You'll architect and build the AI systems that power our advisor-facing and consumer-facing products, working directly with the CTO and product leads to bring ambitious ideas from whiteboard to production.If you're energized by real-world AI problems, thrive in a startup-pace environment, and want to see your work directly shape outcomes for financial advisors and the clients they serve, then this is your role.
What You'll Do- Set Direction: Lead the design, architecture, and implementation of AI/ML systems powering Datalign’s core products, including Halo (our agentic AI framework) and RelationshipAI
- Collaborate: Work closely with product, design, and data teams to turn ambiguous business problems into measurable, shippable AI capabilities
- Deliver: Build and scale LLM systems including retrieval-augmented generation (RAG), tool use/function calling, multi-agent orchestration, and real-time inference services
- Keep It Secure: Implement reliability, safety, and security guardrails for AI products, including PII handling/redaction, access controls, prompt-injection defenses, auditability, and pragmatic human-in-the-loop workflows where needed
- Innovation: Contribute to evolution of our engineering practice with the rapid adoption of AI tools in software development
- Culture: Mentor other engineers and help build a culture of technical excellence, curiosity, and rapid execution
What You BringRequired- 7+ years of software engineering experience, including experience building and operating production AI/ML or LLM-powered systems
- Proven ability to lead technical projects end-to-end with high autonomy and low oversight
- Bachelor’s degree in Computer Science or a related field. Masters preferred
- Strong experience working in Python. Additional experience with TypeScript and/or Go is a plus
- Hands-on experience shipping LLM applications in production (e.g., RAG, tool use/function calling, agentic workflows, fine-tuning/LoRA where appropriate)
- Strong foundation in distributed systems and cloud infrastructure (AWS preferred), including building scalable inference/services and production observability (logs, metrics, traces)
- Strong communication and product sense: you can explain tradeoffs (quality vs latency vs cost vs risk) and align technical work to business goals
Preferred- Experience in fintech, wealth management, or other regulated environments; comfort partnering with compliance/legal on data and AI controls
- Track record of shipping software in fast-moving, resource-constrained startup environments with high ownership
