Jobs at Djinni

Summary

Full Stack Engineer (Node.js, PostgreSQL), remote role focused on building core platform systems for an enterprise AI product, requiring 3+ years of experience, along with a strong algorithmic background demonstrated through achievements in programming competitions, high rankings on coding platforms, or success in algorithm-focused hackathons.

About the company

Our client builds an AI platform that enables enterprises to customize and deploy AI capabilities for their specific needs. The platform team is central to this work, responsible for infrastructure, shared components, and internal tooling that the rest of engineering depends on.

The role

This is a hands-on implementation engineering position. You'll work on deploying, configuring, and integrating the platform for enterprise clients, translating their requirements into working solutions, deployed at client's infrastructures. The role sits between product engineering and customer success: technically deep, but with awareness of real-world client needs.

You'll collaborate closely with platform engineers and business teams, occasionally joining business discussions to clarify technical requirements or explain implementation details.

What you'll work on

• Implementing and configuring platform deployments for enterprise customers
• Building integrations between the platform and client systems
• Working with internal teams to understand client requirements and translate them into technical solutions
• Contributing to implementation tooling, documentation, and repeatable deployment processes
• Troubleshooting and resolving issues during and after deployment
• Occasionally, participating in client calls to gather requirements or provide technical guidance

What we're looking for

• Prize-winning places at programming olympiads (IOI, ICPC, Google Code Jam, Facebook Hacker Cup) or regional competitions.
• High rating on coding platforms: LeetCode (Knight+ or 2000+ rating), HackerRank (Gold+), Codeforces (Expert+ or 1900+ rating).
• Participation in hackathons with a focus on algorithmic problems (for example, victories at HackMIT, AngelHack).
• Strong proficiency in Node.js and TypeScript
• Experience with React and frontend integration
• PostgreSQL/similar RDBMS and general data modeling knowledge
• Familiarity with cloud platforms (AWS, Azure, or GCP), and multi-cloud exposure is valuable
• Clear communication skills - comfortable explaining technical concepts to non-technical stakeholders
• Ability to work independently and manage multiple implementation workstreams
• 3+ years of software engineering experience

Useful additions / nice to haves

• Experience with AI platforms or AI/LLM integration
• Familiarity with CI/CD pipelines and infrastructure-as-code
• Vue.js experience
• Background in enterprise software implementation or professional services
• Previous work in similar roles

• Remote/Hybrid, UK, Chechia, Spain - employment contract, Poland, Romania, Slovakia, Bulgaria, Ukraine - B2B contract.

The role

This is a senior security engineering position with a strong emphasis on penetration testing and threat modeling. You'll work across the full security lifecycle: designing secure architectures, modeling threats, researching emerging attack vectors, and validating defenses through hands-on testing.

The focus is on long-term security improvements — identifying and addressing risks before they become incidents. You'll need both the attacker's mindset to find vulnerabilities and the engineering skills to help fix them properly.

What you'll work on

Key responsibilities

• Lead the transformation of sales into a scalable, AI- and automation-enabled operating model where repetitive work is automated, and the team focuses on higher-value activities: experimentation, process improvement, relationship-building, and conversion quality.
• Define the architecture of sales processes, communicate requirements and set priorities for the implementation team, and continuously improve automation and AI workflows to ensure they outperform manual execution and fit the company’s broader ecosystem as the business scales.
• Improve outreach effectiveness through sharper ICP and buyer persona definition, higher targeting quality, and continuous optimization of AI-assisted messaging, prompts, and workflows.
• Build and operate a predictable revenue engine across outbound, referrals, partnerships, and account expansion channels.

• Conduct sales calls.
• Lead and structure the sales organization, including SDR and Sales Manager functions, with clear accountability, role clarity, and performance expectations.
• Oversee the account management approach for newly won accounts to ensure strong onboarding, relationship continuity, and expansion opportunities.
• Standardize the sales process, CRM discipline, and reporting practices.
• Establish a strong performance management system through KPIs, OKRs, regular reviews, and clear accountability mechanisms.
• Ensure tight alignment between Sales, Marketing, Recruitment, and Operations to support consistent demand generation, conversion, delivery readiness, and client growth.
• Drive a culture of disciplined metrics tracking and real-time visibility into sales process efficiency and commercial performance.
• Consistently build commercial demand ahead of current delivery capacity, while partnering with other functions to help the organization scale responsibly.

• Referral program development.
• Reactivation of former clients and lost opportunities.

• Uses data to challenge assumptions, improve decisions, and constructively raise performance standards.
• Able to operate both strategically and hands-on in a growing company environment.
• Proven ability to hire, coach, and scale a sales team with clear ownership and accountability.
• High standards of performance without resorting to micromanagement.
