What is a founding full stack engineer?

A Founding Full Stack Engineer is an early, core technical team member at a startup who is responsible for building both the front-end and back-end of the company's product. This role goes beyond typical engineering, often involving product decisions, architecture design, and collaborating directly with the founders. Founding Full Stack Engineers help shape the company's culture, technical direction, and can have significant equity stake. Their work is crucial in taking the business from idea to launch, often in a fast-paced, resource-limited environment.

What are the key skills and qualifications needed to thrive as a founding full stack engineer?

To thrive as a Founding Full Stack Engineer, you need expertise in both front-end and back-end development, deep knowledge of programming languages like JavaScript, Python, or Ruby, and experience with scalable architectures, often backed by a degree in computer science or equivalent experience. Familiarity with frameworks (React, Node.js, Django), version control systems (Git), cloud platforms (AWS, GCP), and DevOps practices is typically required. Strong problem-solving, initiative, adaptability, and excellent communication distinguish successful candidates, enabling effective collaboration in a startup environment. These skills and qualities are crucial for building robust products rapidly and influencing the company's technical direction from its early stages.

What unique challenges might a founding full stack engineer face when joining an early-stage startup?

As a Founding Full Stack Engineer at an early-stage startup, you'll often balance building core product features with setting up foundational technical infrastructure. This role typically requires wearing multiple hats, from architecting systems and writing code to making critical technology decisions and collaborating closely with non-technical founders. You may encounter challenges such as ambiguous requirements, shifting priorities, and limited resources, but you'll also have significant influence over the company's technical direction. The dynamic environment encourages rapid learning and offers accelerated career growth, particularly for those who thrive in fast-paced, collaborative settings.

Job description

Full Stack Engineer – WillisRe

WillisRe is building its global technology estate from the ground up, unencumbered by legacy. We are looking for a Full Stack Engineer to build the products that power our reinsurance broking, analytics, and client‑facing platforms. This is a hands‑on engineering role for someone who enjoys working across the whole stack and is equally comfortable building conventional services and AI‑enabled features.

Responsibilities
  • Design, build, and ship end‑to‑end features from APIs and services to responsive user interfaces.
  • Develop and run cloud‑native applications on Microsoft Azure using PaaS, containers, and infrastructure‑as‑code.
  • Consume data through APIs to surface it in performant ways for brokers and analysts.
  • Build AI‑enabled product features using retrieval‑augmented generation, tool and API integration, evaluation, and human‑in‑the‑loop design.
  • Use and promote AI‑assistant engineering tools such as ClaudeCode or ClaudeCowork.
  • Integrate with external market platforms, carrier‑ and client‑systems, and SaaS products via API‑first and event‑driven patterns.
  • Apply test‑driven development and secure‑coding practices, including authentication, authorisation (EntraID, OAuth2.0), data protection, and privacy.
  • Collaborate on architectural standards, participate in design discussions, review code, and mentor teammates in a green‑field environment.
Qualifications
  • 10+ years of professional software engineering experience, shipping and maintaining production systems end‑to‑end.
  • Experience in insurance, reinsurance, or financial services is desirable.
  • Strong backend skills in C#/.NET or Python, API design, and SQL.
  • Proficiency with modern front‑end frameworks (React or Angular) and TypeScript.
  • Hands‑on experience with Azure, CI/CD (AzureDevOps or GitHubActions), and Terraform.
  • Knowledge of microservices, event‑driven, and API‑led design; security fundamentals (OAuth2.0, OIDC, EntraID, RBAC).
  • Strong SQL performance awareness and relational database experience.
  • Experience or strong interest in LLM‑based AI solutions, agentic patterns, prompt design, and evaluation.
  • Fluency in test‑driven development, automated testing, clean design, and judgement about keeping things simple.
  • Excellent communication skills for explaining technical trade‑offs to product stakeholders and delivery partners.
Compensation

$180,000–$220,000+20% bonus

Benefits

Health and welfare benefits, paid time off, 401(k) savings and other retirement programs, employee assistance programs.

Equal‑Opportunity Mandate

We provide equal opportunity to all qualified individuals regardless of race, colour, religion, age, gender, gender expression, national origin, veteran status, disability, orientation, or any other legally protected category.

About WillisRe

Our approach is relationship‑driven, transparent and outcome‑focused. At the heart of WillisRe lies a focus on delivering the most cutting‑edge analytical solutions to enable better decision‑making for risk selection, portfolio optimisation and capital management.
