Jobs at Djinni

We integrate automation, AI, and robotics to build security and defense solutions. Our focus is intelligent systems combining embedded software, computer vision, and edge-AI for autonomous platforms.

We're looking for an engineer driven by the radio spectrum — from spectral analysis to real-time drone signal detection. You'll work with SDR platforms and radar sensors, write DSP pipelines, and collect data.

What you'll be doing:

• Working with SDR platforms (HackRF, USRP, LimeSDR, RTL-SDR) — capturing, analyzing, and processing radio signals;
• Developing DSP pipelines for real-time UAV signal detection, classification, and direction finding;
• Analyzing the spectrum and building signal features for further ML model training;
• Collecting, labeling, and validating radio datasets — laying the foundation for models;
• Working at the intersection of radio and radar — integrating data from radar sensors into a shared detection pipeline;
• Writing in Python and C++ for real-time signal processing;
• Researching and prototyping new approaches to drone detection — this is R&D, not maintenance of something ready-made;

• Working alongside ML engineers to ensure detection models perform reliably on real-world data.

   

Technical skills

Required:

• Understanding of radio engineering fundamentals — modulation (AM/FM/PSK/OFDM), frequency bands, antennas, signal propagation;
• DSP — confident command of digital signal processing: FFT, filtering, spectral analysis, correlation;
• SDR experience — hands-on practice with HackRF / USRP / LimeSDR / RTL-SDR (not just theory);
• Python — confident coding for signal processing and data handling (NumPy, SciPy);
• C++ — for real-time signal processing and high-performance pipelines;
• Linux — comfortable in the terminal, system utilities, SSH;

• Middle / Senior level — ability to independently drive a task from idea to working prototype without step-by-step guidance.

   

Nice to have:

• Radar — understanding of operating principles (FMCW, Doppler), experience with radar sensors;
• GNU Radio — building flow graphs, writing OOT modules;
• Experience with RF front-end, antenna systems, direction finding (DoA);
• TensorRT / ONNX Runtime — deploying models on edge;
• Jetson or other edge platforms;
• Docker / CI/CD;

• English at the level of reading technical documentation and communication.

   

What we offer:

• Impact: work on real autonomous systems, not educational projects.
• Autonomy: technical freedom — choose your tools, propose solutions. Minimum bureaucracy.
• Unique domain: rare expertise that immediately sets your resume apart in aerospace/defence.
• Growth: mentorship from experienced engineers.
• Remote work: remote, flexible schedule, core sync hours for communication.
• Team: work alongside engineers solving problems at the intersection of edge-AI, computer vision, and real-time robotics.

• Mission: direct contribution to Ukraine's defense capability and European security.

   

If this sounds like you — don't wait, reach out today. We look forward to meeting you :)

Our client is a lean, founder-led venture-building studio and family office running a portfolio of businesses across events, hospitality, luxury consumer, media, and investments. The company is building AI-first operating systems so a small team can run multiple businesses at once — removing repetitive admin, improving decision-making, and keeping headcount deliberately low. 

The studio needs one hands-on technical owner for AI and automation across the whole portfolio. Some automations already exist; the mandate is to take them over, rebuild what needs rebuilding, and own a clean, maintainable stack end to end. There is no technical manager above you — you work directly with the founder and the commercial lead, and the architecture decisions are yours.

What you'll work on

AI development & automation — 80%

• AI research agents: vendors, sponsors, guests, brands, venues, market opportunities
• Screening and scoring systems that combine scraped data with hard metrics and business criteria
• Inbox triage, summarisation, and routing; multi-inbox monitoring with decision-ready daily summaries
• Systems that turn unstructured founder inputs (screenshots, voice notes, links) into recommendations and routed tasks
• CRM and outreach workflows, dashboards and trackers, calendar and recurring-task automations

No one has built all of this — what matters is a track record with comparable use cases and the ability to transfer it to new problem types. Expect a fast cadence: first automation live within 30 days, several production workflows by 60–90 days.

Technical generalist — 20% (~1 day/week)

• Keep the operational stack running: Notion (incl. Notion AI), Google Workspace, HubSpot, access management, integrations, troubleshooting, data cleanup

Requirements

• Shipped production automations or AI-powered tools in a real business context — not side projects, demos, or hackathon builds
• Practical fluency with LLMs, APIs, and at least one automation platform (Make, n8n, Zapier, or similar)
• Python or equivalent scripting ability — many builds are achievable low-code, but candidates who can write and debug their own scripts have a higher ceiling
• Experience with vector search, RAG, agent frameworks, function calling, and workflow orchestration
• Ability to design workflows with human approval points, exception handling, logging, and error recovery — systems that fail gracefully and visibly, not silently
• Strong documentation habits — your systems must be maintainable and understandable by non-technical colleagues
• Comfort with ambiguity, shifting priorities, and working independently without full specs or a technical escalation path
• English sufficient for daily written and spoken communication (B2+)

Nice to have

• Experience building internal tools for executives, family offices, venture studios, agencies, or lean startups
• HubSpot or comparable CRM experience

Location requirements

• Fully remote, but your working day must overlap with UK time (GMT/BST) for 6–8 hours daily
• An additional ~2-hour overlap with Malaysia time (GMT+8) is a plus

What to expect

• Greenfield mandate: build and own the AI stack; genuine autonomy, no stakeholder committees
• Cross-portfolio ownership — your systems run real businesses across events, media, luxury, and investments
• Direct access to the founder from day one; radically lean process: a call → a decision → execution
• An expanding role: new ventures continuously add projects, with the prospect of support hires under you as the stack grows

Interview process

1. Recruiter screen (incl. a short portfolio example of an automation you built)
2. Interview with the client
3. Practical assessment
4. Final interview with the founder

Terms

• Remote-first contractor engagement; own equipment required
• 28 days PTO per year, taken freely — covers vacation, sick leave, and holidays in a single policy
• Business travel expenses covered when required

Our client is a B2B SaaS platform operating at the intersection of data intelligence and LinkedIn advertising. The product is in active growth — the engineering team ships continuously, and feature velocity is high. The platform combines LinkedIn Ads optimization, website visitor identification, and revenue attribution in one decision layer — so marketers can see which companies engage with their ads, connect that activity to CRM data, and prove what actually drives deals.

The team is small and senior: a product manager, 3 backend engineers (PHP/Laravel), 1 frontend engineer (React), and 3 data engineers (Python, N8N), on AWS-managed infrastructure with Postgres and Clickhouse. The team works in sprints with sprint planning and retrospectives.

Why this role exists

Two gaps are holding the team back. First, the CTO is absorbing too much coordination overhead: breaking down requirements, running syncs, unblocking developers. Second, testing coverage hasn't kept pace with shipping speed — bugs that automated tests would have caught are slipping through to production.

This role is designed to close both gaps at once. The PM side frees up the CTO by owning task creation and team coordination. The QA side builds an automated testing layer from scratch, with AI tooling at its core. Neither half of this role is a full-time job on its own — together, they're exactly one.

What you'll own

Project management — primary focus

• Receive requirements from the CTO and convert them into detailed, developer-ready tasks and epics in ClickUp, following the company's established task framework
• Run sprint planning and retrospectives, keep the team unblocked, and handle routine coordination without escalating to the CTO
• Own documentation: maintain clear, up-to-date technical specs and requirement breakdowns
• Be the connective tissue between product intent and engineering execution — understand the business logic behind what's being built, not just the task list
• Track progress, flag risks early, and make sure work that gets decided actually gets finished

QA automation — secondary focus

• Build an automated QA framework from scratch — end-to-end, regression, and API testing; choose your own tools and programming language
• Triage and classify bugs by root cause (frontend vs. backend) before routing to developers
• Write test plans and document edge cases; build coverage that actually prevents regressions, not just documents them

Requirements

What we expect from an ideal candidate

• 3–5 years of total experience with at least 1.5 years in a project or product management role and at least 1.5 years in QA engineering
• At least 2 years of that experience must be at a product company
• Proven ability to break down product requirements into clear, structured technical tasks for a development team
• Experience running sprint planning and retrospectives, or working closely within that process
• Strong self-management and prioritization — able to hold multiple threads across PM and QA without dropping things or waiting to be told what's next
• Experience in QA engineering with a demonstrated shift toward automation — manual-only QA is not a fit for this role
• Solid understanding of regression testing and functional testing concepts
• Working knowledge of SQL sufficient to validate data at the database level (Postgres, Clickhouse a plus)
• Ability to distinguish frontend bugs from backend bugs quickly and describe them precisely
• You should be actively using AI tools to automate, build, and accelerate your own workflow
• English B1 or above — sufficient for written communication and technical documentation

Nice to have

• B2B SaaS background in a QA, PM, or hybrid role
• Prior experience with a marketing technology product (attribution, analytics, ad tech, CRM, or similar)
• Strong English (C1) — a plus for communication with native-speaking stakeholders

What to expect from the company

• Investment in your growth — the company is willing to develop this person into a stronger PM and a more capable user of AI tooling, not just hire for what exists today
• An established process framework to work within (ClickUp, sprints) that you can improve over time
• Direct access to decision-makers in a flat, fast-moving structure
• Freedom to choose your own QA tooling and programming language — no mandated stack on the testing side

Interview process

• Recruiter screen
• Interview with the CTO
• Test task
• Final round

Terms

• Location: Ukraine, remote
• Contract: FOP (Ukraine)
• Schedule: Flexible, ~10.00 - 19.00
• PTO: 24 calendar days / year, Ukrainian public holidays observed

• Background in ledger or double-entry accounting systems
• Experience with multi-currency, FX, or cross-border payments
• Contributions to open-source Go projects or payment-related libraries

• Build the product landing-page infrastructure: Create the product, blog, and article pages that unlock both organic rankings and AI citations.

• Own technical SEO and ongoing site health: Resolve the priority backlog (sitemaps, indexing, redirects) and own crawl, indexing, and schema as the site scales.
• Define and execute the content strategy for organic and AI visibility: Decide which content and templates we create, brief the writers, and make sure it targets the topics worth winning.

• Strong technical SEO — you can diagnose and fix crawl, indexing, redirect, and schema issues yourself, using tools like Screaming Frog and GSC.
• Strong analytics — you turn Ahrefs and GSC data into a clear, prioritized action plan.
