Jobs at Djinni

About the role

We're building a performance marketing team, and this role is central to how we grow — owning conversion rates across all marketing touchpoints and the full user journey from first page view to first paid session. You'll work at the intersection of marketing, product, and engineering to generate, test, and scale ideas that move our core metrics: conversion rate, new clients, and CAC.

Responsibilities

• Own conversion performance across all marketing surfaces: main website, blog, landing pages, campaign funnels, and any new acquisition flows.
• Generate, prioritize, and execute CRO hypotheses — from ideation through briefing, prototyping, A/B testing, analysis, and implementation of winning variants.
• Design new funnels for paid channels (Meta, TikTok, and others as we scale), including concept, user flow, messaging framework, and success criteria. Coordinate execution with design, content, and engineering teams.
• Own the post-click experience for all paid traffic — ensure that what happens after a user clicks an ad is optimized for conversion, not just for traffic volume.
• Create and optimize landing pages for campaigns, audiences, and channels — working with designers and developers or using no-code/AI tools where appropriate.
• Monitor and analyze funnel performance at every stage (page view → authorization → first therapy created → first purchase). Identify drop-off points, diagnose root causes, and act on them.
• Run a continuous experimentation process: maintain a hypothesis backlog, manage test calendars, ensure statistical rigor, document results and learnings.
• Write clear briefs and technical specs for product and engineering teams. Communicate the goal, the hypothesis, the expected impact, and the success criteria for every initiative.
• Collaborate with the product team on the authorization-to-purchase flow. Currently owned by product — this role progressively takes over the marketing lens on this funnel, working jointly to improve it.
• Collaborate with the UA/paid channels manager on campaign-to-conversion alignment: ensuring ad creative messaging matches landing page experience, and that conversion signals are properly tracked.
• Participate in tracking and attribution setup alongside analytics — flag data gaps, validate conversion events, ensure the team can trust the numbers.
• Report regularly on conversion metrics, experiment results, and impact on new clients and CAC.

Requirements

• 3+ years in growth marketing, CRO, or a similar experimentation-driven role in a product company (marketplace, SaaS, subscription, or similar).
• Proven track record of improving conversion rates through systematic testing — not just ideas, but shipped experiments with measurable results.
• Strong understanding of user funnels, landing page best practices, and conversion psychology.
• Ability to write clear briefs, create wireframes or prototypes (even rough ones), and articulate what needs to be built and why.
• Hands-on experience with A/B testing tools (Google Optimize, VWO, Optimizely, or built-in product experimentation).
• Comfortable with analytics tools (GA4, Mixpanel, or similar) — able to pull data, interpret funnel reports, and make decisions based on evidence.
• Understanding of event-based tracking: how user events and parameters work, how they trigger flows, and what breaks when tracking is misconfigured.
• Strong cross-functional communication skills — this role lives between marketing, product and engineering daily.
• Structured thinking and ability to prioritize based on expected impact vs. effort.

Nice to have

• Experience with mental health, wellness, or other sensitive/high-trust products where aggressive conversion tactics don't work.
• Experience creating funnels for Meta Ads or other paid social channels specifically.
• Familiarity with no-code tools for landing pages
• Understanding of paid acquisition economics (CAC, LTV, ROAS) and how CRO improvements cascade into unit economics.
  
  What we offer:
• An opportunity to work on a health tech product that improves people’s mental well-being worldwide;
• Flexible schedule and full remote work- no strict location requirements;
• A team of passionate professionals who love what they do and foster an open, supportive atmosphere where every idea is heard and creativity is encouraged;
• Fully remote work with an option to visit our cozy office in Kyiv;
• Competitive compensation, based on your qualifications and experience;
• Paid time off 33 days per year (including public holidays);
• Paid sick leave  10 working days per year;
• Budget for learning and development;
• Paid mental health leave (5 working days per year)

Senior Individual Contributor · Onsite/Hybrid Contractor · Kraków, Poland
 

Project description (direct hire)

We're a small, technically driven team building automated trading infrastructure on Ethereum. Our system detects arbitrage opportunities, routes trades across multiple third-party venues, and submits transactions to block builders for inclusion within a single block.

We're not a pre-revenue experiment. We're profitable, backed by world-class investors, and funded by our own live trading operations. That gives us the freedom to focus on what actually matters: expanding our strategies, sharpening execution, and building infrastructure that holds up when real money is on the line.

About the role

We're looking for a senior engineer to share ownership of our core trading logic and infrastructure. This is a hands-on individual-contributor role — no managing tickets, no proxy work. You'll be equally at home writing high-performance Rust, debugging a bundle-inclusion failure on-chain, and shipping services to Kubernetes in production.

You'll work across the full lifecycle of a trade: opportunity detection and scoring → quote aggregation across multiple routers → bundle construction → submission to block builders. Because the system handles real money, correctness, safety, and reliability are non-negotiable. You'll also own the risk-management layer — the automated short circuits and kill switches that monitor P&L in real time and pull trading back when thresholds are breached.

If you think about failure modes, rollback plans, and kill switches before the first line of code, you'll fit in well here.
 

What you'll own

• Trading strategy & execution. Design and implement arbitrage detection, opportunity scoring, and execution logic inside a Rust actor architecture that processes every new block in real time.
• Liquidity routing. Build and maintain integrations with aggregator APIs and self-hosted routers — quote collection, comparison, and optimal route selection across multiple liquidity sources.
• MEV bundle construction. Build and submit bundles to block builders, optimizing for gas efficiency, inclusion probability, and profit extraction, while interacting with multisig wallets and custom smart contracts.
• Automated risk controls. Develop systems that monitor balances, detect anomalies, and autonomously scale trading deployments down via the Kubernetes API when something looks wrong.
• Production infrastructure. Operate and evolve the platform end-to-end: deploy to AWS EKS, manage multi-account environments with Terraform, build Grafana dashboards, query logs through Loki, and own production troubleshooting.
   

Our stack

Rust · tokio · revm / Foundry · alloy / ethers-rs · PostgreSQL · Kubernetes (EKS) · AWS · Terraform · Grafana · Loki · Solidity / Gnosis Safe
 

What we're looking for

• 5+ years of software engineering experience, with a track record on complex backend systems and real ownership of technical domains from concept to production.
• Strong, demonstrable Rust expertise — async, concurrent code with tokio, trait-based abstractions, solid error-handling patterns, and comfort in performance-sensitive code paths.
• A real understanding of Ethereum's architecture: transactions, blocks, gas mechanics, ERC-20s, DEX mechanics, and the MEV supply chain (searchers, builders, relays). You understand why things are designed the way they are, not just how to call them.
• Experience building or operating systems that handle real money or critical infrastructure — you reason about failure modes, monitoring, kill switches, and rollback as a default.
• PostgreSQL proficiency: writing and optimizing queries, designing schemas for high-throughput time-series data, and managing migrations.

Nice to have

• Prior MEV experience: Flashbots, block builders, bundle submission, or searcher-strategy development.
• Hands-on work with Rust Ethereum libraries (alloy, ethers-rs) or EVM simulation tools (revm, Foundry/Anvil).
• Production Kubernetes (EKS) and AWS experience — deployments, secrets management, VPC networking, Terraform.
• Smart-contract development (Solidity/Foundry), especially Gnosis Safe modules or DeFi protocol integrations.
• Familiarity with DEX aggregator APIs and the trade-offs between on-chain and off-chain routing.

Location & engagement

This is a long-term contractor / subcontractor engagement. The role is anchored in Kraków — ideally you're based there. We'll also consider strong candidates elsewhere in Poland who can travel to Kraków regularly (roughly once a month, for a few days). Several of our team members are already on the ground there.

Why this one's worth your time

Most "Web3 developer" roles are CRUD with a wallet connect button. This isn't that. You'll own a real data and execution plane, ship to production, and see the direct P&L impact of your code on a system that's already live and profitable — with the autonomy of a senior contributor and none of the big-company bureaucracy.

If that sounds like your kind of problem, get in touch and we'll share the deeper technical details and terms.

As a Senior Growth Analyst at Readdle, you'll own the numbers behind how Spark grows and proactively discover opportunities and validate the impact of initiatives. From the first ad impression to long-term renewals, you'll make sense of the data, design event structures, and ensure everything is measurable. You'll dig into funnels, uncover insights, and build dashboards that make growth performance crystal clear for product and marketing teams.

What will you do:

• Transform and analyze large datasets in BigQuery and Amplitude to discover product & growth opportunities, trends, anomalies, and actionable insights across the user journey.
• Build and maintain self-serve reports that enable stakeholders to answer key questions with data and establish a clear source-of-truth for growth metrics.
• Define, document, and QA event structures for new features, campaigns, and experiments; build a robust monetization measurement system to support pricing and migration decisions.
• Analyze user funnels across ads, store, onboarding, in-app usage, purchases, and cancellations to identify drop-offs and growth opportunities.
• Design, sequence, and monitor A/B experiments and feature launches; validate results and ensure statistical rigor & consistent long-term impact tracking.
• Proactively surface insights, hypotheses, and growth opportunities to marketing and product teams; shape quarterly prioritization with discoveries from data and impact scenarios to influence roadmap decisions.
• Build forecasting and scenario models for installs, conversions, retention, and revenue.
• Ensure data integrity across tools and pipelines through established QA processes; work with measurement vendors to meaningfully track attribution and optimize acquisition reporting.

About you:

• 5+ years in growth, product, or marketing analytics in a B2C or SaaS environment, with experience working on user acquisition, pricing, monetization, and/or migration initiatives in subscription-based products.
• Strong SQL skills and experience with BigQuery or similar cloud data warehouses (Redshift, Snowflake); proficiency in Tableau/Looker/etc. for reporting and complex data visualization and product analytics tooling. Amplitude/Mixpanel/Heap/Hotjar/PostHog for event/property tracking and user journey tracking.
• Experience with marketing attribution platforms (Appsflyer/Adjust/Kochava/etc.); familiarity with Python/R for data analysis and automation. Experience with ML or time-series inference is a strong plus.
• Solid understanding of product analytics (funnels, cohorts, retention, event tracking), marketing analytics (incl. attribution, MMM, incrementality testing, etc.), statistics, experimentation, and experience with segmentation and modeling churn or LTV. Demonstrable advanced analytics experience (causal inference, quasi-experiments, linear programming, econometrics, etc.) is highly advantageous for the role.
• Proven ability to design self-serve dashboards and act as a strategic thought partner to PM/PMM teams, not just an executor of analytics requests.
• Solid business acumen. Comfortable working cross-functionally with product, marketing, and engineering teams with a proactive, curious, and coachable mindset.
   

What you will get at Readdle:

• Customer-centric culture. We put our users at the heart of everything we do. Every team member has the opportunity to engage directly with customers, gaining insights that shape meaningful, delightful experiences for millions worldwide.
• Relentless growth. We’re committed to mastery in our craft. We take ownership of our work, decisions, and outcomes, and we see feedback as a catalyst for growth. Every challenge is an opportunity to learn, evolve, and raise the bar.
• Exceptional people, exceptional team. Our greatest strength is our people. We care deeply about each other, work transparently, and celebrate collective success. Together, we build an environment where everyone can do their best work and grow beyond their potential.
• Real impact. We design products that truly matter. Our focus is on delivering tangible value, simplifying complexity, pushing boundaries, and continuously improving how we build and deliver solutions to our users.
• Culture of innovation. We embrace curiosity and creativity in everything we do. Fresh ideas are not just welcomed, they’re expected, celebrated, and turned into real innovations that shape the future of our products and company.

Requirements:

• Strong production experience with Vue.js
• Solid Python experience for backend development
• Proficiency with JavaScript / TypeScript for frontend development
• Hands-on experience with Three.js and Canvas-based rendering
• Demonstrable frontend performance optimization experience (page load time, rendering efficiency, working with large or real-time data sets)
• Ability to work highly autonomously, proactively clarify requirements and drive work forward with minimal supervision
• Strong communication skills and experience working in distributed teams (Europe/Ukraine time zone; ~1–2 hours of daily overlap with a US-based team)
• Hands-on experience with AI-assisted development tools — e.g. Claude Code and Codex — including AI skills, plugins, and MCP (Model Context Protocol), with a clear understanding of how to boost personal productivity and code quality using AI tooling

Nice-to-Have:

• React experience — a planned Vue → React migration is in scope for the team, so familiarity with both frameworks is a strong plus
• Hands-on experience migrating a frontend from Vue to React
• Experience rendering large, real-time data streams in the browser
• Familiarity with deck.gl and Leaflet
• WebGL experience beyond Three.js abstractions
• Familiarity with C++ or general backend development

Key Responsibilities:

• Build and maintain features across a portfolio of Vue-based projects
• Develop and support Python backend services
• Optimize frontend performance — faster page loads and more efficient rendering of heavy real-time 3D scenes and data
• Build and maintain visualization UI components that render synchronized 3D, lidar, and media data
• Contribute to the planned Vue → React migration as it ramps up
• Take ownership of features end-to-end, proactively clarifying requirements and assumptions
• Collaborate with a primarily US-based team with ~1–2 hours of daily overlap, while working largely independently

About the Project:

You'll join the engineering team of a leading technology company building autonomous mobility and robotics systems. The team develops an internal data visualization platform — essentially a "video and data player" that renders a 3D scene, a lidar feed, and an audio feed in sync, used to inspect and debug the data recorded by autonomous vehicles.

The work centers on a set of Vue-based projects, including the platform itself and supporting Python backend services, with a Vue → React migration on the roadmap as the broader engineering organization standardizes on React. This is a long-term engagement for an engineer who is comfortable across the stack, cares about clean and performant code, and can drive features from design to production with high ownership and minimal supervision.
