Careers at Kennis OS

We are building the shared platform that powers every product in the Kennis ecosystem. Join a team where infrastructure work has exponential leverage.

Our Mission

Why Kennis OS Exists

Every product in the Kennis ecosystem needs authentication, database access, AI capabilities, and event-driven communication. Building these independently for each product would mean duplicated effort, inconsistent security, and fragmented data. Kennis OS exists so that products inherit world-class infrastructure instead of reinventing it.

Shared Infrastructure

We build the auth, database, and hosting layer that every Septimius product inherits. One platform team, 14+ products served. When you improve the platform, every product gets better.

KORA AI Assistants

We build and scale the AI layer — RAG pipelines, embedding services, and per-product KORA instances that give fund managers, property operators, and investors an intelligent co-pilot.

Developer Experience

We create the SDK, CLI, and APIs that internal and external developers use to build on the platform. TypeScript types, OpenAPI docs, and tooling that makes shipping effortless.

Who We Are

Kennis OS is the platform team within the Kennis ecosystem. We are part of Kennis Wiser Capital — a purpose-driven investment platform deploying institutional capital into ESG real estate, infrastructure, and technology.

We are a small, senior team responsible for the infrastructure that 14+ products depend on. Every decision we make has downstream consequences — so we care deeply about reliability, security, and developer experience.

If you want to build platform infrastructure that serves an entire ecosystem of institutional products, we would like to hear from you.

Work Life Philosophy

How We Work

Health is Wealth

We're not prescriptive about our policies. We don't dictate the time off you should take, nor do we set any kind of vacation schedule. As long as your objectives are met, and there's no negative impact to your team and clients, then you can choose your days and weeks.

Work Smarter

We believe in your ability to work smarter, not harder. We strongly support flexible working. As long as your workload is well managed and completed, it's immaterial the hours you work, or your location. We will support you by giving you the tools to work smarter.

Family First

We have a fully paid, gender neutral Maternity and Paternity leave policy. We recognise that one of the most special events in an individual's life is the birth and/or adoption of a child. Our paid parental leave is flexible and generous.

Giving Back

We will match any donations you make up to the value of £2,500 to an organisation of your choice, providing they comply with our company's ethical guidelines.

Our Values

Integrity

We do what we say. The products built on our platform depend on our reliability — we treat that trust as sacred.

Excellence

We hold ourselves to institutional standards. Row-level security, immutable audit trails, and 99.9% uptime are not aspirations — they are baselines.

Impact

Every platform improvement we ship multiplies across 14+ products. We optimise for leverage, not busywork.

Collaboration

We work across every product team in the ecosystem. Great platform engineering requires deep empathy for the teams you serve.

Interview Process

What to Expect

Verbal Case Interview

A structured conversation exploring how you think about problems. We present a platform scenario — a scaling challenge, a security design, or an API trade-off — and discuss your approach. No preparation required.

Experience Interview

We explore your background and what you have built. Platform engineers may discuss infrastructure decisions. AI engineers may walk through a RAG pipeline. We want to understand how you have solved real problems.

Written Case Interview

You receive a design brief — an API specification, an event system architecture, or a data migration plan. Write a short memo with your approach and trade-offs. Designed to be completed in a few focused hours.

Why Join Kennis OS

Multiplier Effect

When you improve auth, every product gets better auth. When you improve the AI layer, every KORA instance gets smarter. Platform work has exponential leverage.

Infrastructure at Scale

Supabase PostgreSQL, Vercel edge, Cloudflare CDN, real-time event streams. You will operate production infrastructure serving institutional clients.

AI-Native Platform

KORA isn't a feature bolted on. It's a platform service with embeddings, RAG, and per-product knowledge bases. You will build AI infrastructure, not just chat interfaces.

Developer Tools

You will build SDKs, CLIs, and APIs used by every team in the ecosystem. The DX bar is high — TypeScript types, OpenAPI specs, and zero-config scaffolding.

Security by Design

Four-tier data classification, row-level security, correlation IDs on every event. Security is architectural here, not a compliance checkbox.

Small Team, Vast Surface

The platform powers fund management, property ops, energy, carbon, and AI. Few infrastructure teams serve this many domains. The learning is unmatched.

Departments

Platform Engineering

Core infrastructure — auth, database, event bus, hosting. TypeScript, Supabase, Vercel.

AI / ML

KORA assistants, RAG pipelines, embedding services, and model integration.

Developer Experience

SDK, CLI, API documentation, component library, and developer tooling.

Security & Compliance

Row-level security, data classification, audit trails, and GDPR compliance.

Current Openings

We are always looking for exceptional talent. Even if we do not have a specific role listed, we welcome speculative applications from people who share our values.
