Youll have ownership of end-to-end projects, the autonomy to lead from idea to implementation, and the opportunity to work across product lines - from scalable APIs and secure infrastructure to machine learning.
The role also brings unique engineering challenges shaped by regulatory and compliance requirements - pushing your creativity and technical capabilities.
Who You Are:
A product-minded engineer who loves solving problems at scale
Comfortable owning full systems - from architecture to deployment
Passionate about writing clean, maintainable code with an eye on the end user
A collaborative team player who mentors generously and learns continuously
Curious, thoughtful, and excited by a fast-moving environment
What Youll Actually Be Doing
Design, build, test, and deploy backend systems for high-scale financial applications
Lead architecture reviews and drive decisions across technologies and platforms
Write well-tested code and review peers work for quality and clarity
Collaborate with Product, DevOps, and Security teams to deliver seamless experiences
Own and improve development lifecycles including CI/CD, observability, and cloud automation
Debug production issues and lead efforts to ensure system reliability and uptime
Contribute to internal documentation and onboarding processes
Participate in a Tier 2/3 on-call rotation to support business-critical systems.

We are looking for a Senior Full Stack Engineer who thrives at the intersection of intelligent systems and polished product experiences. You'll work across the entire stack from designing React interfaces that surface AI capabilities to engineers and end users, to building the Python and Node.js services that power our LLM-based Agentic platform. A key part of this role is hands-on experience with designing, building, and integrating MCP servers that connect our AI agents to internal tools, financial data systems, and third-party APIs. You'll collaborate closely with product, compliance, and cross-functional engineering teams to build financial technology that's fast, secure, and genuinely intelligent.
Who You Are:
You have experience building Retrieval‑Augmented Generation (RAG) systems or knowledge‑base chatbots.
You're Hands‑on with vector databases such as Pinecone, Chroma, or pgvector on Postgres/Aurora.
Have AWS certification (Developer, Solutions Architect, or Machine Learning Specialty).
Experience with observability tooling (Datadog, New Relic) and cost‑optimization strategies for AI workloads.
Background in microservices, domain‑driven design, or event‑sourcing patterns.
What Youll Actually Be Doing:
Design, build, and continuously improve our LLM-based Agentic platform. Own end-to-end architecture decisions from model orchestration and prompt design to retrieval pipelines, tool-calling patterns, and evaluation frameworks.
Architect and build high-performance services in Python and/or Node.js. Design systems for extreme speed, reliability, and real-time data processing under high traffic conditions.
Design and maintain MCP servers that give AI agents structured, secure access to internal banking systems, external APIs, databases, and developer tools making Agentic platform composable and extensible by design.
Build intuitive React interfaces that expose AI capabilities like chat interfaces, agentic dashboards, real-time streaming UIs, and internal tooling. Own state management patterns and component architecture at scale.
Partner with product managers, business stakeholders, compliance, and engineering teams to translate vision into scalable technical requirements and roadmaps.
Design and ensure the platform meets enterprise-grade security and financial regulatory standards.
Actively upskill fellow engineers on full-stack best practices, LLM integration patterns, and production of AI systems. Help define coding standards and contribute to a culture of engineering excellence.
Evaluate emerging models, frameworks, and tooling. Prototype and integrate the most impactful advances into our platform and internal developer productivity tooling.
Requirements

we're building the financial infrastructure that powers global innovation. With our cutting-edge suite of Embedded payments, cards, and lending solutions, we enable millions of businesses and consumers to transact seamlessly and securely. With 900+ employees worldwide and an R&D center of over 160 employees in Jerusalem - were reshaping how financial technology is developed and delivered.
The Role:
Staff software engineer is our most senior individual-contributor role. You report to a VP of Engineering and act as the technical force multiplier across the several teams that VP owns through their Engineering Managers. Engineering Managers own people and delivery. You own the technical bar.
Who You Are:
You turn strategy into architecture, make the hard design and build-versus-buy calls, and keep decisions coherent across every team under the VP. You work in three modes: lead technical direction, help unblock and grow teams, and build the highest-risk pieces yourself. Hands-on. Not a manager. Your leverage is architecture, code, and the engineers you make better.
What Youll Actually Be Doing:
* Partner with the VP to translate business goals into cross-team technical strategy and clear architecture.
* Own the hard technical decisions: system design, service boundaries, data models, stack choices, and the tradeoffs behind them.
* Define the standards teams build against: coding, testing, security, observability, operational readiness.
* Drive alignment across Engineering Managers and their teams so independent decisions hold up at the platform level.
* Unblock teams on the hard problems: scale, latency, reliability, thorny integrations, production incidents.
* Take initiative without being asked: spot gaps, propose the fix, and drive it across teams before it becomes a problem.
* Actively grow and mentor engineers. Invest in their technical development, coach through hard problems, and build the next tier of senior talent.
* Prototype and ship the highest-leverage, highest-risk code yourself so teams inherit a proven path.
* Set the bar for quality, security, and compliance in a regulated, Real-Time financial environment.
Why Youll Love Working Here:
* Flexible hybrid model: 3 days a week in the office - A must
* 1,000 net monthly wellness benefit - from therapy to Pilates to your kids art class
* Full Keren Hishtalmut, private health & dental insurance
* Donation matching, volunteering days, team outings, and mentorship programs
* A mission-driven culture that values ownership, trust, and meaningful impact
