Jobs at Djinni

DroneOps specialises in advanced navigational systems for UAV operations. Our focus is on developing robust solutions that enhance UAV autonomy and reliability, facilitating operations in environments where traditional GPS may be compromised. Our technology is designed to be integrated across a range of UAV platforms, delivering precision, resilience and cost-effective enhancements to existing hardware.

We are looking for an embedded software engineer to own the platform layer of our onboard computing: the Linux images our navigation software ships on, the provisioning and secure boot chain that protects it in the field, and the tooling that turns a bare Raspberry Pi Compute Module into a flight-ready device. Our team is small and cross-functional. You will work close to the hardware and close to the people writing the algorithms that run on it, with real ownership of the platform from the first week.

MUST HAVE SKILLS

• 3+ years of commercial experience with embedded Linux (for the Senior level; from 2 years for Middle)

• Strong Linux internals: boot flow, initramfs, systemd, journald, udev, device tree and overlays, kernel modules

• Hands-on experience with Raspberry Pi as a production platform, not only as a dev board — Compute Module 4 / 5, EEPROM and bootloader configuration, rpiboot / usbboot

• Building custom OS images: pi-gen, rpi-image-gen, or an equivalent stack (Yocto, Buildroot, debootstrap)

• Secure boot in practice: signed boot images, key management, OTP-fused key hashes, encrypted or verified rootfs (dm-crypt / LUKS, dm-verity)

• Experience with device provisioning pipelines: key injection, per-device identity, factory-side automation

• Flashing and mass-provisioning workflows: reproducible builds, image verification, recovery from a bricked device

• Confident CLI, bash and Python scripting for build and provisioning automation

• Cross-compilation and toolchain fundamentals (ARM64)

• Git and CI-driven builds (GitHub Actions)

• Reading schematics and datasheets well enough to talk to hardware engineers

• At least Intermediate English (reading docs, written async communication)

NICE TO HAVE SKILLS

• A/B (dual-slot) update schemes and OTA frameworks: RAUC, Mender, SWUpdate

• U-Boot, custom kernel configuration and patching, PREEMPT_RT

• Peripheral bring-up: UART, I2C, SPI, GPIO, CSI cameras, PPS/GNSS receivers

• ArduPilot, PX4, MAVLink or another autopilot stack

• Other SoM platforms: NVIDIA Jetson, i.MX, Rockchip

• Hardware-accelerated video and computer vision pipelines on ARM (V4L2, GStreamer, VPU/GPU offload)

• Information security fundamentals: PKI, HSM or KMS-backed signing, secrets handling, threat modelling for physically accessible devices

• Self-hosted GitHub Actions runners for image build pipelines

• Docker for reproducible build environments

• Power management and thermal constraints on airborne platforms

• Experience with restricted or air-gapped development environments

YOUR TASKS MAY INCLUDE

• Designing and maintaining the Raspberry Pi OS images our navigation software runs on — minimal, reproducible, versioned

• Building and operating the secure boot and provisioning chain: signing keys, OTP key programming, encrypted rootfs, factory provisioning stations

• Automating image build, signing and flashing in CI, so a release is an artifact rather than a manual procedure

• Bringing up new hardware revisions and peripherals together with the hardware team

• Implementing and testing a safe field update mechanism, including rollback

• Debugging boot, driver and performance issues on real devices — serial console, ftrace, perf, kernel logs

• Hardening the platform: attack surface reduction, secrets storage, protecting IP on a device that can be physically captured

• Writing the technical documentation and runbooks for the platform you own

WHAT WE OFFER

• Competitive salary

• Reservation from mobilization

• Office in Kyiv with shelter access, generator and Starlink

• Possibility of hybrid work format

• Impact on improving our country's defense capabilities

• 21 days of vacation + public holidays, sick leaves

PSP Manager

Experience: 5+ years
Industry: iGaming / Payments / FinTech
Level: Senior / Managerial

For our partner, we are looking for PSP Manager.

About the Role

BetLive is looking for an experienced PSP Manager to take ownership of the effectiveness and development of our payment infrastructure across target markets.

This is a senior business-focused role combining payment strategy, business development, commercial negotiations, financial analysis, and PSP portfolio management.

You will be responsible for continuously assessing whether our payment infrastructure supports business growth across all target markets, identifying gaps and opportunities, developing existing PSP relationships, sourcing new payment solutions, and negotiating strong commercial terms.

A key part of the role is having a holistic view of payment flows and business performance. You will analyze incoming and outgoing turnover across PSPs, GEOs, payment methods, currencies, and customer segments, considering conversion, approval rates, fees, reserves, settlements, limits, chargebacks, operational risks, and other factors affecting payment efficiency and profitability.

Based on this analysis, you will provide top management with clear recommendations and proposed actions to improve payment performance, reduce costs and risks, increase successful transaction volumes, and support business growth.

Key Responsibilities

• Own and continuously assess the effectiveness of the company's payment infrastructure across target markets.
• Analyze incoming and outgoing payment turnover across PSPs, GEOs, currencies, and payment methods.
• Evaluate payment performance considering transaction volumes, approval and conversion rates, processing costs, FX, rolling reserves, settlements, limits, chargebacks, payout performance, and operational risks.
• Identify gaps, bottlenecks, dependencies, and growth opportunities within the existing payment infrastructure.
• Translate payment data into business conclusions and actionable recommendations for top management.
• Propose actions to increase payment conversion and successful turnover, optimize costs, improve payout performance, and reduce payment-related risks.
• Identify where additional PSPs, payment methods, acquiring solutions, currencies, or alternative payment options are required.
• Develop the PSP portfolio in line with business growth and GEO expansion plans.
• Source and evaluate new PSPs, acquirers, payment gateways, APMs, and other payment partners.
• Lead commercial negotiations and secure competitive terms, including transaction fees, MDR, reserves, settlement conditions, limits, FX costs, and other commercial parameters.
• Develop existing PSP relationships and regularly renegotiate conditions based on volumes, performance, and business potential.
• Evaluate the overall business value and economics of existing and potential PSP partnerships.
• Monitor PSP performance and initiate corrective actions when performance, commercial conditions, or service quality do not meet business expectations.
• Ensure sufficient diversification and redundancy of payment solutions across critical GEOs and payment methods.
• Coordinate PSP onboarding and development with Finance, Product, Compliance, Legal, and technical teams.

• Stay informed about payment market developments, new providers, technologies, payment methods, and competitor practices.

   

Requirements

• 5+ years of experience in PSP management, payment business development, payment partnerships, acquiring, or a similar role.
• Strong experience in iGaming or another high-volume international online business.
• Strong commercial and business acumen, with the ability to connect payment performance with broader business results.
• Proven experience managing and developing PSP relationships and negotiating commercial conditions.
• Strong understanding of incoming and outgoing payment flows, acquiring, payment gateways, APMs, settlements, reserves, chargebacks, FX, and payment routing.
• Strong analytical skills and ability to work with payment turnover, conversion, costs, and profitability metrics.
• Ability to identify patterns and problems in payment data and turn them into concrete business actions.
• Experience preparing recommendations and presenting payment insights to senior/top management.
• Ability to evaluate PSPs from commercial, operational, technical, risk, and strategic perspectives.
• Strong negotiation and relationship-management skills.
• Experience working cross-functionally with Finance, Product, Compliance, Legal, and Tech teams.

• English sufficient for negotiations and daily communication with international partners.

   

What We Offer

• Opportunity to work with two international online casino brands focused primarily on Tier 1 markets (EU).
• Direct impact on the company’s payment strategy, business performance, and international growth.
• High level of autonomy and ownership in developing and optimizing the PSP portfolio.
• Direct communication with top management and involvement in strategic business decisions.
• Opportunity to influence payment infrastructure, provider selection, commercial conditions, and expansion into new markets.
• Work with both fiat and cryptocurrency payment solutions.
• Flexible cooperation format depending on expertise and availability: full-time, part-time, project-based, or advisory/consulting engagement.
• For advisory/project cooperation, the scope can include payment infrastructure audit, gap analysis, PSP portfolio review, turnover and payment-flow analysis, commercial optimization, recommendations to management, and support with PSP negotiations and new provider selection.
• International and fast-moving business environment with a focus on practical results and measurable improvements.

What We Value

We are looking for someone who sees payments as a business growth and profitability function, rather than simply a set of providers and integrations.

The right person should be able to look at the complete payment picture — turnover in and out, conversion, costs, provider performance, market coverage, risks, and commercial conditions — understand where the business is losing opportunities or money, and recommend concrete actions to management to improve the result.

About Company

BetLive operates two online casino brands focused on international markets, with a primary focus on Tier 1 GEOs.

Our products offer a full online casino experience and support both fiat and cryptocurrency payment methods, allowing players across our target markets to deposit and withdraw using a range of relevant payment options.

As our brands continue to grow and expand into new markets, we are strengthening our payments function to ensure reliable payment coverage, strong conversion, efficient payment flows, and commercially sustainable relationships with payment providers.

About the Product

We build a marketing data platform for the pharma industry. Our clients are pharmaceutical brands, and the campaigns reach verified healthcare professionals.

The platform enables marketing teams to run campaigns across channels such as Meta, LinkedIn, and programmatic advertising, and to measure campaign performance. The core product is a Laravel + Vue application running on GCP, backed by PostgreSQL and analytical data platforms including ClickHouse and BigQuery.

The team is small, fully remote across EU time zones, and releases continuously.

We are looking for a Lead Platform Engineer to own the technical direction of a web platform used by pharma marketing teams to run and measure their campaigns.

This is a hands-on technical leadership role: you will lead a small team of developers and QA while continuing to write code yourself. You will decide how features should be built, document the approach in an FRD, align it with the CTO, and take it through development, review, release, and production. You will report directly to the CTO and work closely with the Product Lead, who defines what we build and why.

Soft Skills

• You lead through action: break down work, review code, unblock engineers, mentor, and make technical decisions.
• Strong written communication skills in English, especially for FRDs, technical decisions, and code reviews.
• Analytical and systematic approach to problem-solving; you look for the root cause before proposing a fix.
• Strong task and priority management; you identify and communicate risks early.
• Comfortable saying no or challenging an approach when there is a strong technical reason.
• Careful and responsible approach to sensitive data, including access control, consent, and PII.

AI Baseline

AI-assisted development is a core part of how we work. From day one, we expect:
