Senior iOS Engineer - DevEx

**🚂About Pulley** Pulley's mission is to make it easier for anyone to start a company. We believe that more startups should exist and that founder-led companies are more successful in the long term. With Pulley's cap table management tools, companies can better understand and optimize their equity for the long term. Starting a company is hard enough. Managing equity shouldn't be. We're a high-performing team on a mission to redefine how early-stage leaders build and manage their companies in an AI-native world. As AI reshapes how businesses operate, we see a unique opportunity to reimagine equity and business management from the ground up. A brand-new, unsolved challenge that we're excited to tackle. Pulley is growing quickly with over 4,000 customers, including startups like Linear, Runway, Fathom, and Roam. Our trajectory is fueled by top investors like Founders Fund, Stripe, General Catalyst, Caffeinated Capital, 8vc, Elad Gil, and other incredible angels. All of our growth has been organic, and we're expanding the team to meet the growing demand. We're looking for passionate, execution-focused self-starters to help us build the next generation of tools for founders. **🌟 About the role** We're looking for a Senior Software Engineer to build the features powering AI capabilities across our core equity platform. You'll own end-to-end delivery across the stack — from backend services that orchestrate agentic workflows and tool integrations, to frontend experiences that bring AI-powered features to life for users. In this role, you'll work closely with product and design to turn ambitious ideas into real product improvements, moving fast while maintaining the quality and scalability our platform demands. **🛠 What You'll Do**

*   Build and maintain features end-to-end — from backend services in Go powering agentic workflows and tool integrations, to polished frontend experiences that bring AI capabilities to users
*   Implement APIs and service interfaces that connect AI capabilities to our core product reliably and at scale
*   Ship complex, multi-step workflow orchestration with strong reliability and observability
*   Build frontend features that leverage AI to enhance and simplify equity workflows for users
*   Drive performance improvements across the stack — caching, database optimization, and responsive UI
*   Mentor junior engineers on best practices and system design

**🙌 What You Bring**

*   5+ years of full-stack engineering experience building production systems
*   Strong proficiency in Go and TypeScript/React, or equivalent backend and frontend experience — ideally balanced across the stack
*   Experience integrating LLMs or AI capabilities into production applications
*   Familiarity with agentic frameworks and tool orchestration patterns
*   Solid API design skills and experience with service-to-service communication
*   Experience with PostgreSQL, Redis, and system observability in production
*   Clear communicator who can turn product requirements into well-scoped technical plans

**Nice to have**

*   Proficiency in Go and TypeScript/React
*   Experience with Temporal or similar workflow orchestration frameworks
*   Background in fintech or regulated industries
*   Familiarity with AI-powered developer tools like Cursor or Copilot

**✨ Why work at Pulley**

*   **We've moved beyond early-stage uncertainty** - Our product has traction and we're building on a solid foundation, but we're still early enough in our journey where your work will directly shape the company's trajectory as we scale.
*   **Make it easier for anyone to start a company** - Founders turn bold ideas into reality - building things that might not exist otherwise. Starting a company is hard enough. Managing equity shouldn't be. Pulley exists to make equity management simpler, smarter, and more accessible for founders from day one.
*   **Work with a high-performing and passionate team** - We value the concept of stunning colleagues and we're thoughtful about creating a team that is excited about building a great company together. Here are some traits that enable our team members to thrive:
*   **First Principles Thinking** - We believe in breaking down problems into their most basic parts, and that something is possible unless proven otherwise. We understand "why did certain things work?" and apply it to our situation.
*   **Ship It & Iterate** - We value people who not only generate ideas but also do the work to bring them to life. Instead of fixating on outcomes, we focus on the inputs we can control and take our best bets. We move quickly to ship something, talk to users, get feedback, and iterate.
*   **Boldly Honest & Aggressively Considerate** - Being boldly honest means challenging each other to set and hit goals, and make the right strategic decisions on what to build. Being aggressively considerate means caring about one another as humans and speaking up with empathy so we can succeed together as a team.
*   **Ego-less Learner** - Everyday at Pulley, we're trying things that we've never done before - sometimes they work; sometimes they don't. It's important to embrace the mindset of a beginner - stay curious, open to feedback, and ready to learn and grow alongside the team.

**💚 Benefits**

*   Competitive salary and equity
*   Medical, Dental, and Vision insurance
*   Unlimited PTO + Winter holiday break
*   Parental leave
*   Generous stipends for WFH, learning, wellness, and AI tools

Staff Engineer Software

**About Euphoric**

Euphoric builds AI-first employee benefits administration software for the world’s largest and most prestigious employers. Born out of Peppy Health — a fast-growing, category-defining Series B startup — we spun out in May 2025 to tackle a far bigger opportunity.

Global employers spend $3–5 trillion on benefits every year. It’s their second-largest cost after payroll — yet the entire category is still running on legacy systems and outdated assumptions. The space is primed for transformation: despite its scale, it’s been almost completely overlooked by AI-first startups. Incumbents — including one U.S. heavyweight with $2B+ in annual revenue — are constrained by archaic tech stacks and can’t move fast enough to innovate.

And this isn’t just a massive market — it’s genuine “tech for good.” Smarter benefits administration, richer analytics, and clearer communication have the power to directly improve the everyday lives, wellbeing, and financial security of millions of employees worldwide.

We’re a sharp, high-velocity team with bold ambitions, obsessed with building category-defining technology and partnering with exceptional people who want their work to truly matter.

We closed our seed round in October 2025 and are building from a position of strength with a long cash runway.

**The Role**

We are looking for a Lead AI Engineer to drive the technical evolution of our AI-first platform and serve as our resident expert. You won't just be tuning hyperparameters in a notebook; you will be a core software engineer architecting the complex systems that make AI useful in production.

In the immediate future, your time will be split between crafting complex AI processing architectures (40%) and hands-on data/backend engineering (40%), with the rest spent doing whatever is needed to ship. As we mature, your focus will shift toward closing the loop: using real-user data to optimize the platform via online evaluation and targeted, data-driven models.

**What You’ll Do**

*   **Architect & Engineer AI Systems:** You won’t just call an API; you will build robust processing architectures that leverage off-the-shelf LLMs, RAG pipelines, and context engineering to solve hard problems. You will benchmark these systems rigorously to ensure they actually work, not just "feel" smart.
*   **Build the Backend Foundation:** You will spend significant time in Python (FastAPI, SQLAlchemy) building the APIs, data structures, and services that power the product. You are an engineer who ensures the "AI" is delivered on reliable, production-grade rails.
*   **Close the Data Loop:** As we launch, you will lead the transition from "zero-shot" implementations to data-driven optimization. You will instrument data collection, design online evaluation metrics, and deploy simple, effective ML models (e.g., logistic regression, boosted trees) to optimize user outcomes based on real feedback.
*   **Be a "Full Stack" Partner:** While the backend/data is your home, you are willing to jump into the frontend (React/TS) to implement features (AI or not) or debug an integration. You understand that an algorithm isn’t "done" until the user interacts with it successfully.
*   **Mentor & Lead:** You will work alongside full-stack engineers, upskilling the team on AI concepts and best practices. You are the "from-the-trenches" expert who helps the team distinguish between Twitter hype and engineering reality.
*   **Strategic Advising:** You will help Product and Leadership navigate the map of what’s valuable and what’s possible, steering the roadmap toward features that achieve business impact through data-driven optimization.

**Skills & Experience**

*   **Production Engineering (5+ years):** You are a strong software engineer first. You have extensive experience building and maintaining backend services in Python (ideally FastAPI or similar async frameworks) deployed to modern cloud providers (GCP/AWS) or point solutions (Railway, Render, Vercel)
*   **Applied AI Architecture:** You have built complex applications using Foundation Models / LLMs. You understand context window management, prompting strategies, and how to chain models together to achieve reliable results.
*   **True ML Fundamentals:** You aren't limited to APIs. You have a background in training and evaluating models (TensorFlow/PyTorch/Keras/Scikit-learn) and know when a simple classifier is better than a generative model.
*   **Data Fluency:** You understand how to build datasets from scratch (bootstrapping, crowdsourcing) and how to evaluate them (cross-validation, precision/recall, business metrics).
*   **Team-Oriented Mindset:** Strong communication skills for explaining complex ideas to technical and non-technical audiences, and a passion for collaborating within cross-functional teams.
*   **Passion and Pride in Shipping:** A do-whatever-it-takes attitude to deliver against important business goals that help the entire team win.
*   **Pragmatic Best Practices:** An overarching desire to build efficient, scalable, and maintainable code, while managing the tradeoffs between technical debt and delivery speed. You’d rather ship a heuristic that solves the user's problem today than a perfect model two weeks late.

**What We Look For**

We’re a great bunch but we have some "Euph" cultural non-negotiables. To do well here you will:

*   Thrive in fast-paced, feedback-rich environments
*   Take your work seriously, but not yourself
*   Be proactive, playful, and deeply curious
*   Want to build something that matters
*   Be willing to “do what it takes”

**What You’ll Get**

*   Base salary c£140k
*   Remote-first setup with optional shared work space passes and a hub in London
*   Apple devices and the best AI tooling
*   Private healthcare via Vitality
*   3% employer pension contribution (min 3% employee contribution)
*   Meaningful early-stage share opportunities
*   25 days holiday per year, plus bank holidays.
*   Career rocket fuel - real growth, real ownership, real impact
