Integrations Engineer

About Axle

Axle is building the intelligent infrastructure for how capital moves on Wall Street.

Trillions of dollars in institutional capital get directed through a web of relationships, meetings, and decisions that still run on spreadsheets, email chains, and tools built over a decade ago. This is the layer where markets actually move, and we're at the forefront of rebuilding it.

We have replaced all of it with one platform, powered by AI agents that strip out the manual work and give bankers strategic leverage. Axle is quickly becoming the operating system for Wall Street's most important relationships.

The investment banks already running on Axle treat us as mission‑critical, and we are just getting started. The problems we work on are high‑stakes, data‑dense, and critical to how markets function.

Our founding team blends Wall Street experience with engineering excellence, drawing on backgrounds at firms like Goldman Sachs, Bank of America, AWS, and Capital One. We lived the problem firsthand and built the platform we wished existed. Our tight‑knit team in NYC is backed by top‑tier VCs and former leaders from JPMorgan, Goldman Sachs, and Citadel.

About the role

We're looking to hire an Integrations Engineer. This is a hands‑on IC role building the systems that connect Axle to our customers' world: CRM sync, data migrations, email, identity, and industry feeds. You'll own them end to end, including in technical conversations with customer and vendor teams alongside Product and Customer Success.

What you'll own

• Build the integration platform. Shared connectors, data models, and mapping layers that bring a new customer online through configuration, not custom code.
• Move data reliably. CRM sync, bulk ingestion, and migrations from legacy platforms, with validation, reconciliation, and monitoring that catches problems before customers do.
• Own enterprise connectivity. Email delivery, calendar, SSO, and file‑based feeds to industry platforms.
• Be the technical voice. Join customer and vendor technology calls with Product and Customer Success to scope integrations and own the technical answers.

What you bring

• 4+ years building production backend or integration systems, with strong experience in Java/Spring Boot or TypeScript.
• Clear, confident communication on technical topics with customer and vendor engineering and product teams.
• Hands‑on experience with CRM or SaaS API integrations (Salesforce, Datazoic, etc.) and data pipelines: field mapping, validation, deduplication, and reconciliation.
• Deep relational database knowledge, particularly PostgreSQL, including schema design, migrations, and answering hard data questions yourself.
• Experience building on AWS with event‑driven architecture: serverless, queues, object storage, and email infrastructure (SES, SMTP).

Nice to haves

• Experience with enterprise identity: SAML, OIDC, SSO, and user provisioning.
• Experience in capital markets or financial services data, such as CRM, research, or corporate access platforms.
• Experience with infrastructure as code such as Pulumi or Terraform.

Why this role at Axle

Every bank that runs on Axle depends on the systems you'll own. You'll hear the problem directly from customers and vendors, design the system that solves it, and watch every future launch get faster because of it. No layers between you and the work.

What to know

We are a startup serving institutions that operate under real pressure, and sometimes that pressure lands on us. There will be times you work long hours or respond outside classic windows because a customer or a deal demands it. We balance a lot at once, and we ask everyone to carry real weight. In exchange, you get outsized ownership, a steep learning curve, and a seat at the center of how markets work. We're in our Flatiron office in New York five days a week because we build faster together.

Benefits & perks

• PTO: Unlimited
• Salary & equity: Competitive compensation with real upside
• Insurance: Medical, dental, and vision - fully covered
• Eats & commute: Lunch and commute stipend, plus office snacks and drinks
