Jobs at Djinni

c3 is a research-led startup based in London and Kyiv. We are expanding our team and research and are seeking an RF engineer as part of this expansion. 

Requirements

• Strong background in RF sensing and wireless signal processing: channel state information (CSI), RSSI, multi-carrier/OFDM systems, amplitude/phase extraction, multipath, and the physics of RF propagation.
• Hands-on experience with real RF/wireless hardware data. You should have dealt with noisy channel estimates, phase instability, hardware/carrier frequency offsets, antenna effects, calibration drift, and the gap between clean lab captures and messy real-world signals.
• Strong understanding of RF signal-to-information inversion: extracting physical meaning from raw wireless measurements, and reasoning rigorously about what is and isn't recoverable from a given signal.
• Experience solving temporal sensing problems: detecting sustained change in a physical environment against a learned baseline, and separating genuine events from transient or cyclical confounders.
• Familiarity with the electromagnetic behaviour of materials (attenuation, permittivity, frequency-dependent effects, multi-band sensing) is highly valuable.
• Strong Python and PyTorch skills, with experience building production-quality evaluation and inference pipelines.
• Experience with classical estimation alongside ML — Kalman/particle filtering, Bayesian inference, change-point detection, or equivalent — not only deep learning.
• Experience with signal-processing toolchains (NumPy/SciPy, spectral analysis, filtering) and, ideally, embedded RF platforms (ESP32, SDR, Nordic, or similar).
• Experience with synthetic data generation / physical simulation for augmentation and controlled failure-case generation.
• WiFi sensing, radar, RF localization, IoT sensing, wireless communications, or defence signals experience is highly relevant.
• Fluent English.
• Kyiv-based preferred; hybrid or remote considered.

What you will do

• Build robust detection pipelines that extract a reliable physical signal from cross-link RF data while remaining insensitive to everyday environmental variation.
• Handle noisy channel estimates, phase drift, packet loss, hardware offsets, and differences between devices and deployments.
• Build temporal detection and classification that distinguishes genuine sustained events from transient activity, environment-wide confounders, and cases of insufficient evidence.
• Develop confounder-rejection reasoning so that environment-wide effects are not misclassified as localized events.
• Build multi-band and cross-link inversion using physical models and learned features, followed by robust localization.
• Define confidence / failure detection for detection and localization results rather than forcing a result from bad signals.
• Develop event classification and severity scoring once the underlying signal is sufficiently reliable.
• Create synthetic perturbations and physics-based generated training/evaluation data covering known failure modes.
• Own evaluation against ground truth, including detection rate, false-positive/negative rate per unit-time, localization accuracy, timing error, and uncertainty calibration.
• Evaluate alternative sensing representations and fusion approaches — including multi-band spectral methods, time-of-flight techniques, and integration with external contextual data — where they materially improve fidelity.

Manual QA Tester (Project-Based)

We're a small, bootstrapped product ecosystem — currently including a QR code generation SaaS platform, with additional products in active development. We're looking for a Manual QA tester to join our pool of trusted contributors: someone we bring in project by project, feature by feature, as new work comes up across our products.

This is not a fixed-hours role. There's no guaranteed weekly commitment. Instead, you'll be paid per project/feature you test, and — if it's a good fit on both sides — you'll be first in line when new work lands. Over time this can mean steady, recurring engagement; it just isn't structured as employment.
 

What You'll Do (per project)

• Perform regression, acceptance, GUI, smoke, and sanity testing as relevant to the feature, project or deployment
• Run test cases, checklists, and exploratory tests against a defined scope
• Report and track bugs (Jira, jam.dev)
• Update and improve test cases in Qase.io
• Communicate findings clearly with the product/dev team, with a clean handoff at the end of each project

Requirements

• Experience with manual QA testing (test design, bug reports, execution)
• Familiarity with Qase.io (or similar test management tools)
• Strong English
• Comfortable working independently within a defined scope, with minimal onboarding per project
• Kyiv timezone (UTC+2) or close

Nice to Have (But great as a bonus)

• API testing (Postman)
• Experience with AI tools (e.g. ChatGPT, Claude) for test case generation

Tools We Use

Qase.io • Jira • Slack • Toggl • Jam.dev

Work Setup

• Remote, project-based, flexible scheduling within each project's timeline
• Team communicates in English and Ukrainian
• Work spans multiple products in our ecosystem — expect some context-switching between projects rather than deep specialization in one product

Application Process

1. Video (1–2 minutes):
   • In English: What motivates you to be a QA tester?
   • In Ukrainian: What is your current career challenge, and what are you doing about it?
   • (Simple phone recording is fine. Share via Dropbox or similar.)
2. Resume review
3. Short paid test assignment (scoped, so you can see how we work and we can see how you work)

4. Decision & pool onboarding

The project

You will own the development of a capability for scientific models - a custom application we are building on the Datagrok platform for one of our pharma customers. It's a central place where scientists register, discover, run, and compare computational models. Models come from different teams, in different languages, with different inputs and outputs. Your job is to turn that into one coherent, fast, self-service experience.

This is not a ticket-driven role. You will "sit" with the customer's scientists, understand how they work, and translate that into working software.

Responsibilities:

• Develop clean, high-performance, well-documented, production-level code
• Own your backlog: prioritize, estimate, communicate status, and drive features from a conversation to production
• Talk directly to the scientists and computational modelers: run demos, gather requirements, challenge assumptions, propose better ways to solve their problems on the platform
• Contribute improvements back to the platform and public plugins where the project uncovers gaps

Requirements:

• Expert-level TypeScript: you've designed and shipped non-trivial TS applications or libraries in pre-LLM era
• Engineering range: building elegant solutions from scratch, evolving complex existing codebases, and contributing efficiently across the whole stack, UI to backend
• Past projects in scientific or life-sciences software, complex modeling, or scientific computing (e.g., simulation engines, computational tools, statistical modeling apps, numerical/HPC code, etc.)
• Fluent spoken and written English: you will be in customer-facing meetings weekly, presenting your work and negotiating scope with scientists
• Willingness to learn new scientific domains
• Demonstrated ability to self-manage: you've owned a project or major workstream end-to-end and can point to something that shipped because you drove it to completion

Nice to have:

• Scientific background (STEM / life sciences)
• Python, R, C++, or Julia (enough to read and integrate scientists' model code)
• Experience with ML development and/or model lifecycle tooling (model registries, MLflow-style tracking, workflow engines)

We offer:

• Fully remote work
• Excellent growth opportunities in a highly dynamic, unique product company
• Zero bureaucracy
• Paid trainings and certifications
• Competitive compensation

We are looking for a remote, full-time Sales Specialist to join our team, manage the sales process, run product demos, close deals, and onboard new clients.

Key responsibilities:

• Manage the full sales cycle: qualify leads, conduct product demos, understand client needs, handle objections, negotiate, and close deals;

• Onboard new clients: guide them from signup to a confident and effective start on the platform, providing initial product and strategic support;

• Help clients build and refine their SEO/link-building strategy using Collaborator.pro, aligned with their business goals;

• Attend industry conferences and events worldwide as a company representative and contribute to networking and lead generation;

• Collect client feedback and share insights with the product and internal teams to improve the user experience.

What we’re looking for:

• Proven experience in sales, including managing the sales process and closing deals;

• Previous experience in SEO and link building (guest posts, backlinks, PR placements, outreach, etc.);

• Strong English communication skills (spoken and written), with confidence presenting to clients;

• Strategic mindset and the ability to recommend optimal approaches for using the platform;

• Willingness and ability to travel internationally for conferences and events is required;

Benefits of working with us:

• Freedom in making decisions that will help to achieve the project KPIs – we value proactivity and are always open to new ideas;

• The opportunity to improve your professional skills while working with a growing IT platform;

• 22 working days of vacation per year and paid sick leave.

Other perks:

• A welcoming team, ever-ready to lend a hand.

We're a 20-person team building a browser-native scientific data platform used by Novartis, J&J, Daiichi-Sankyo, and other top pharma and biotech companies. Our platform was already 10x faster than the competition and delivered more value for less — even before the AI era. Now, we're taking it to the next level.

We're competing with Spotfire, Certara, Dotmatics, and Schrödinger — and winning. How? By building faster and smarter. Our engineering team has fully embraced AI-driven development (Claude Code, agentic workflows, AI-assisted testing), and it's become our biggest force multiplier. We ship in weeks what used to take quarters.

We're looking for an engineering leader who's already living this way — someone who has hands-on experience with agentic development tools and can help lead a team that's pushing the boundaries of what a small, focused group can deliver. You'll report directly to the CEO and have real authority to shape how we build.

What you'll build and lead

This isn't a "manage meetings and write status reports" role. You'll own critical product areas and ship alongside the team. Here's what's on the roadmap:

• AI-powered agentic workflows — Autonomous scientific agents that utilize Datagrok's plugins and integrations as tools.
• Automated testing at scale — Automatic scenarios using Playwright + AI, AI-driven bug reproduction and fixing, stress tests, unit tests, system health tests, plugin tests - everything integrated into CI-CD and managed by AI
• Platform evolution — Cross-application integration and eventing mechanicm, ClickHouse as an analytical backbone, high-performance computations
• Enterprise integrations — Databricks connectivity (ADBC/Arrow for 2–10x speedups), HuggingFace model integration, and dashboard importers for Tableau and Spotfire migrations
• DevOps and infrastructure — ArgoCD deployments, Docker image management, containerized dev environments, and OpenTelemetry observability across a multi-layer stack
• AI-powered knowledge graph — mapping source code, features, tests, docs, and Jira tickets to enable impact analysis and agentic development workflows across the entire codebase
• Process improvements - code reviews, better planning/outcome system, DX improvements, onboarding for new developers

What we're looking for

Must have:

• You've already adopted autonomous agentic development in your own workflow (harnesses, tool-use architectures, AI-driven testing, etc)
• 5+ years as a strong engineer who still codes. This is a hands-on position
• Experience leading a team (formal title matters less than demonstrated leadership)
• Proficiency in TypeScript or Dart; comfort picking up new languages fast. Our core stack is Dart and TypeScript, with C++/WASM, Python, R, Julia, and Matlab in scientific plugins
• Track record of delivering complex software products — not just managing people who do
• You see a problem, you fix it. You don't write a proposal about fixing it. You don't wait for permission
• Strong communication skills and fluent English — you'll work directly with technical clients at pharma companies and present to enterprise IT teams

Strong pluses:

• Life sciences, cheminformatics, or bioinformatics background (or genuine curiosity about this space)
• Experience building agentic AI systems — not just prompting LLMs, but designing autonomous pipelines, harnesses, tool-use architectures, or AI-driven testing frameworks
• Background in high-performance computing, data visualization, or scientific computing
• Startup DNA — you've built things from zero, worn multiple hats, and thrive without a playbook

What we offer

• Real ownership — reporting directly to the CEO, you'll lead critical product areas for a platform deployed at top-10 pharma companies, not maintain someone else's legacy code
• An AI-first engineering culture — we're not "exploring AI adoption." We've already made the transition. You'll help take it further
• Direct client impact — your work will be used daily by scientists doing drug discovery at companies you've heard of
• Startup speed, enterprise clients — the autonomy and pace of a small team, with the validation of Fortune 500 deployments
• Fully remote, zero bureaucracy, flexible hours, unlimited PTO
• Competitive compensation with growth equity opportunity
• Paid training and certifications
