Software Engineer

Comand AI; Paris; On-site; EUR 90,000 - 170,000; Full time

Benefits offered by this job

Competitive base + equity package

Paris or London based

Client-site travel

Job summary

Comand AI is building next‑generation C2 software used in live defense deployments. You’ll join the engineering team, own end‑to‑end features on Prevail, and work on geospatial data paths between backend and frontend.

We expect strong Python (FastAPI) and TypeScript, a full‑stack orientation, EU citizenship, and comfort with ambiguity. The role is Paris or London based with occasional client‑site travel, and offers base compensation plus equity.

Qualifications

• Full-stack experience preferred; if not full-stack, a genuinely strong backend lean is required.
• Comfortable owning a feature end to end: scoping it, building it, and deciding what not to build, without a PM pre-slicing the work.
• Solid Python (we use FastAPI) and TypeScript.
• EU citizenship (contractual requirement tied to our defense contracts).
• Real comfort with ambiguity: the roadmap here shifts with the deployment pipeline.

Responsibilities

• Own end-to-end features on Prevail, from scoping through shipping.
• Work on real geospatial problems with map-backed data flows and PostGIS queries.
• Build and harden ML/LLM workflow orchestration, with retries, queueing, and long-running jobs.
• Design for on-prem and appliance deployment, focusing on resource constraints.
• Spend time with users in the field when deployments call for it.

Tools

PostGIS

LangGraph

LangChain

Job description

Comand AI's mission is to build next-generation C2 software with real users in real deployments in the field. We are fully indexed on the success of every single user, which means the software you ship runs inside live defense operations, not a benchmark.

You'd be joining the engineering team working directly with Paul, our CTO. You take a problem, explore it, come back with proposals, and iterate; nobody hands you a fully specified ticket. Most of the team genuinely values that exposure. It isn't a dealbreaker if you're very strong but less drawn to it, but expect real user contact to be part of the job.

What this looks like in practice:

• Own end-to-end features on Prevail, our operational planning platform, from scoping through shipping

• Work on real geospatial problems: everything in the product lives on a map, so you'll move data between backend and frontend through tile servers and lean on PostGIS for geo queries that need to be genuinely smart

• Build and harden ML/LLM workflow orchestration: most product workflows carry an LLM or ML step, so you'll design for retries, queueing, and long-running jobs with LangGraph and LangChain

• Design for on-prem and appliance deployment: our default target isn't cloud-native, it's hardware plus software shipped as an appliance, so you're thinking about resource constraints instead of adding another Lambda

• Spend time with users in the field when a deployment calls for it

Who We're Looking For

We filter hardest on mission drive, low ego, and resilience under pressure. We want people who reason from first principles rather than lean on memorized patterns, and who ship rather than over-plan.

Must-have:

• Full-stack experience preferred; if not full-stack, a genuinely strong backend lean is required

• Comfortable owning a feature end to end: scoping it, building it, and deciding what not to build, without a PM pre-slicing the work

• Solid Python (we use FastAPI) and TypeScript

• EU citizenship (contractual requirement tied to our defense contracts)

• Real comfort with ambiguity: the roadmap here shifts with the deployment pipeline

Nice to have:

• Experience with PostGIS or other geospatial data work

• Experience with LangGraph, LangChain, or orchestrating multi-step LLM workflows

• Experience deploying software on-prem or as an appliance rather than pure cloud-native

• Prior work in defense, government, or dual-use tech

What\'s In It For You

• Competitive package (top 0.1% of compensation in Europe: base + equity)

• Paris or London based

• Client-site travel is part of the role when a deployment calls for it

The Process

1. Talent screening: 30 min, online. Background and motivation.

2. Technical test with Paul: 60min, online. Skills assessment.

3. Onsite in Paris: half day. Product demo, a project presentation, a system design exercise, and a re-engineering exercise on an existing codebase.

4. Roundtable.
