Freelance Senior Software Engineer Django

Morning Laffitte

Engineering

Hybrid

Contract

Context

As demand accelerates on Symbiotic Code, we are opening a contracting mission to strengthen the engineering team on high-impact deliverables, with a focus on speed, quality, and strong autonomy.

The role

As a Contractor Software Engineer, you will join the team to take ownership of well-scoped engineering topics, deliver iteratively, and integrate into our existing development flow (PRs, reviews, quality gates, deployments).

Must-have expectations

• Strong autonomy on a Django (Python) stack (no planned upskilling on these fundamental)
• Testing discipline (useful tests, reproducibility) and systems thinking (performance / reliability / security impact)
• Mission-first mindset: willingness to “cross the aisle” and contribute where the mission needs it
• Ability to operate in a demanding environment (quality, security, ownership)

Responsibilities

• Own a topic end-to-end (technical scoping, implementation, tests, documentation, delivery)
• Participate in the team’s development cycle: PRs, code reviews, feedback loops, iterations
• Maintain production-grade quality (robustness, security, readability)
• Communicate clearly on progress, risks, and trade-offs

Project section (examples of contractor-friendly topics)

These are examples (non-exhaustive) and may evolve:

• Database split to enable a future single-tenant deployment (migration / progressive separation)
• GitLab integration (existing spec)
• Prompt management migration (from client to backend)
• Security backlog (bug bounty-related issues)

Contractors are expected to be fully part of the team’s development flow (reviews like everyone else). Core vision / research topics will typically be handled by full-time engineers.

Engagement details

• Target daily rate (TJM) / budget: €600 / day
• Contract: 3 months, renewable
• Equipment & compliance: use of a Symbiotic Security laptop (Vanta) + a Symbiotic Security Gmail account
• Location: Morning Laffite - 3 days in the office / 2 remote days
• Renewal: based on project progress and evolving needs

Process (contractor flow)

A faster process than full-time hiring:

• Needs qualification (stack / budget)
• Remote technical assessmentincluding:
• Algorithm & logic
• Architecture: asynchronous systems, scalability, project structure and delivery

Nice to have

• Python / Bun
• Security mindset / AppSec sensitivity (or interest in leveling up in a security-focused context)

How to apply / next steps

Please share:

• Your CV or LinkedIn
• Links to code (GitHub, PRs) when possible
• Your daily rate, start availability, and preferred rhythm (days/week)
