Founding Full Stack Engineer
The Company
Mythras is a pre‑seed startup building an intelligence infrastructure layer for professional service firms. We are tackling the institutional memory gap in a $6t industry by capturing the high‑stakes judgment that generic AI consistently misses. We have validated the commercial problem with partner‑level leaders at top‑tier firms and are now moving from Proof of Concept to MVP. Technically, this means building systems that combine explicit semantic models, event‑driven capture, and controlled LLM orchestration. not simply wrapping APIs. Our founding team brings a proven track record of scaling business intelligence platforms alongside deep, first‑hand domain expertise from the top of the management consulting world.
The Role
As our first engineering hire, you are expected to be more than a developer. You will work directly alongside the founders and a specialised Knowledge Engineer to translate high‑level semantic and reasoning models into a secure, performant, and user‑friendly enterprise platform. While you will not be responsible for designing the underlying knowledge models themselves, you will be the primary bridge between deep intelligence and a production‑grade product. This is a hands‑on, zero‑ego role. You will be writing production code daily while helping shape the architectural decisions that will define the company for years to come.
Core Responsibilities
Initial focus (first 6–9 months):
* Infrastructure & Architecture: Design and deploy a secure AWS or GCP environment, including CI/CD pipelines, database schema design, and API orchestration.
* MVP Development: Build and ship the core web application (frontend and backend) to support multi‑tenant data ingestion, state management, and visualisation.
* Agent Integration: Implement deterministic orchestration logic for LLM‑based agents, including execution flows, state handling, prompt management, and observability. This is not prompt tinkering — it is about building reliable intelligence workflows.
* Security & Compliance: Implement SOC2‑ready security foundations from day one (we are not expecting certification at MVP), including encryption at rest and in transit, robust identity management, and tenant isolation.
Traditional Requirements
* 4+ years of professional software engineering experience (startup experience preferred).
* Full‑stack proficiency: Strong experience in a modern backend language (Python, Node.js, or Go) and a modern front‑end framework (React / Next.js).
* Databases: Solid understanding of relational databases (PostgreSQL) and a working interest in non‑relational systems (vector stores, graph databases).
* DevOps fundamentals: Experience with Docker and cloud‑native deployments.
* Experience building early‑stage systems that later scaled is a strong plus.
Who This Role Is For
* Enjoy building foundational systems from first principles.
* Care about correctness, traceability, and real‑world decision‑making impact.
* Want genuine ownership rather than a narrow ticket queue.
* Are excited by complex, interdisciplinary problems at the intersection of software, reasoning, and human judgment.
This role is not for you if you:
* Want a fully formed product, large team, or rigid roadmap on day one.
* Prefer narrow, well‑defined problem spaces with little ambiguity.
What We Offer
* Compensation: c. £75k per annum.
* Equity: Meaningful founder‑level equity, structured to reflect early risk and long‑term ownership.
* Ownership: A direct seat at the strategy table and full technical agency over the codebase.
* Trajectory: We expect to raise a pre‑seed round in the near term, with scope to revisit compensation post‑raise.
