Jobs at Djinni

We are looking for a Senior Full Stack Engineer to join a fast-growing, AI-native startup that is rebuilding the software behind defence, aerospace and industrial supply chains. This is a founding-engineer-style role: you will own features end to end instead of picking up tickets. You will work closely with the founders, Deployment Strategists and other senior engineers to turn messy, manual workflows into semi-autonomous processes. You will start in Warsaw with the team, and the plan is to relocate to the US (San Francisco) within about six months, with visa sponsorship and relocation fully covered. This role suits a builder with strong full-stack skills, a passion for shipping and a real wish to move to the US and grow with an early-stage company. Success here means shipping useful, clean and maintainable code that delivers real value to customers.

Details:

• Schedule: Full time
• Location: Onsite – Warsaw, Poland (initial period, co-living provided), then relocation to San Francisco, US within ~6 months
• Start: ASAP
• Duration: Long-term
• English: Fluent
• Type of collaboration: Internal Employment
• Relocation: E-2 / O-1 visa sponsorship and full relocation support to the US

About the project:
The company is building a back-office operating system for defence firms. It helps them find, review and bid on government RFQs, both directly with the Pentagon and as subcontractors. Every year the US government buys billions of dollars' worth of parts and products, but the process is still full of red tape, emails, PDFs and legacy systems. The company's AI-native platform ingests this fragmented data and turns manual procurement and distribution workflows into semi-autonomous processes. It pairs the platform with forward-deployed engineers who work on-site with customers until their toughest operational problems are solved. The startup is backed by a top accelerator, has 7-figure ARR and is scaling quickly across defence, aerospace and industrial sectors.

You have:

• Strong, genuinely full-stack experience: TypeScript/JavaScript, React/Next.js and a backend in Node.js or Python
• Solid experience with PostgreSQL and SQL
• A strong track record that shows engineering excellence, for example: a top technical university, a reputable software house or product company, an elite internship, competitive programming or hackathon results, or past founder experience
• Builder mindset: side projects, open-source contributions, hackathons or 0-to-1 ownership
• Comfort with autonomy, ambiguity and a fast-paced, demanding startup environment
• Clear communication: you can explain and defend your ideas, set reliable deadlines and meet them
• Customer-focused approach: you see code as a way to deliver value and you own your work end to end
• Readiness to relocate to the US within about six months of starting
• Fluent English

Nice to have:

• Experience with complex integrations, data ingestion pipelines or ERP systems
• Experience with Svelte
• Daily use of AI coding tools
• International experience (study or work exchange abroad)
• Startup or founding-engineer experience

What to do:

• Build and ship full-stack features end to end on an AI-native platform for defence and industrial procurement
• Design and build data ingestion pipelines and integrations that turn fragmented data into structured workflows
• Work closely with founders, Deployment Strategists and senior engineers to understand customer problems and solve them
• Write useful, clean and maintainable code, and set a high bar for engineering quality across the team
• Spot and fix bad practices that could hurt the product long term, while making smart trade-offs when needed
• Set reliable deadlines, communicate progress clearly and raise concerns early
• Help shape the engineering culture of a fast-growing early-stage team

You will be the person who opens it. You will prospect, pitch, negotiate and close in French, then work with our team in English to get partners live and growing. You report to the CEO, with no sales layer above you and no SDR team feeding you leads.

Your priority is offering companies white-label infrastructure to sell own inventory via programmatic pipes, PMPs, PGs, RTB, SDK, VAST, GAM etc. Also, we offer white-label DSP, SSP solutions for publishers, ad networks and agencies that want their own branded exchange without building one.

What we look for

• Experience selling to publishers, ad networks or agencies in ad tech: SSP, exchange, ad network, monetisation platform or agency side.
• Native or near-native French, and professional English, written and spoken.
• Existing relationships with clients in French-speaking markets.
• You understand SSPs, header bidding, Prebid, SDK and how an exchange makes money, well enough to explain a white-label exchange to a publisher's CEO and to know when to bring in engineering.
• You run your own time and pipeline, and you keep at least three hours of daily overlap with Central European Time.

Useful but not required: selling in both France and French-speaking markets, web, app or CTV inventory, CRM and e-signature tools, a network at regional events, and (if you are interested) French for conversations that cross into Brazil or other markets you can cover.

What we offer

• 100% remote, from any country.
• Fixed base salary plus bonus (12 month commission on every deal).
• 24 days of paid time off, as a floor rather than a ceiling.
• The territory, the pipeline and the number are yours.
• A direct line to the CEO on every meaningful deal.

We are hiring Forward Deployed Engineers (FDEs) - senior, product-minded builders who are handed a goal, not a backlog, and own it from the first conversation to a shipped product.You will embed directly with the product and business teams who have the problem, and deliver end-to-end.

What you'll own:

• Projects, end-to-end. Take an idea or a problem from discovery -> design -> build -> ship -> iterate, with minimal oversight. You are accountable for the outcome, not just the code.
• Embedding with the teams who own the problem. Sit close to HP's product and business teams, understand what actually matters, and translate ambiguous needs into working software.
• Build fast, then harden. Stand up prototypes in days to validate an idea, then evolve the winners into robust, fully realized products.
• Scope, sequence, and protect delivery. Break an open-ended problem into clear workstreams, sequence them, make explicit trade-offs between scope, speed, and quality, and remove blockers before
they cost you.
• The whole stack. Work across frontend, backend, data, infrastructure, and AI - picking the right tool for the job rather than the one you know best.
• AI as a force multiplier. Use AI coding tools and agentic workflows aggressively to design, build, and ship more - and faster - than a traditional team would.
• AI-native products. Integrate LLMs, agents, retrieval, and real-time / voice capabilities into real products, with the judgment to know when AI is the answer and when it isn't.
• Close the loop with the business. Own a measurable outcome, not just a deliverable - track the metrics that matter, understand how each project creates value, and let impact guide what you build next.
• Feed learnings back into R&D. Share what worked and what didn't, and codify the patterns that work into reusable tools, playbooks, and building blocks the whole team can build on.

Must-haves:

• Deep seniority (7+ years). A track record of owning significant systems or products end-to-end.Evidence of real delivery matters more than a job title.
• True end-to-end / product engineering. You can take something from zero to one and all the way to a shipped, live product by yourself - design, implement, deploy, and operate it - across the full stack.
• AI-native to the core. This goes without saying for us: agentic coding tools like Cursor, Claude Code, and Codex are part of your daily workflow, not an occasional experiment - you build with AI by default.
You stay current with a fast-moving ecosystem and fold new capabilities into how you work the moment hey land.
• Problem decomposition. Handed a vague, open-ended problem, you structure it into a clear plan, reason about the cost and consequence of each option, and prioritize ruthlessly toward impact.
• High autonomy and ownership. You thrive in ambiguity, set your own direction, unblock yourself, and consistently deliver without being managed.
• Exceptional communication. Outstanding written and spoken English. You can run a working session, present a direction, write a crisp doc, and align people who don't think like engineers. For an FDE this is non-negotiable - it is half the job.
• Bias for speed and impact. You ship, learn, and iterate quickly. You would rather validate an idea in a week than perfect a plan for a month.
• Business sense. You understand how businesses work, what the metrics mean, and how the thing you are building actually creates value - and you use that to prioritize.

 

Bonus points
• Experience building AI / LLM products that shipped to real users - agentic workflows, RAG, evaluation frameworks, guardrails, and real-time / voice.
• A 0-to-1, startup, founder, or consulting background - you have worn many hats and been close to customers.
• A portfolio of side projects, open source, or shipped work that shows range and initiative.
• Comfort being embedded with non-technical stakeholders and business teams.
