Jobs at Djinni

About the Role

We’re hiring a Senior Full Stack Engineer who can own major surfaces across backend, data, frontend, and system design. The product fuses data ingestion pipelines, graph/DAG operations, LLM-driven agent chains, copilots, and media generation. You’ll architect, build, and harden production features with autonomy. Expect ambiguous problems, tight loops, and high standards. This is an early stage startup culture which means moving fast, collaboration with a small team to architect and deliver features, doing more than planning, customer driven feedback, and managing change and uncertainty.

Core Responsibilities

• Deliver production ready SaaS capabilities end to end including develop and launch agent systems, GraphRAG with copilot experience, data tree visualizations
• Own integration points for AI and media generation (Claude Sonnet, FAL.ai, Remotion/FFmpeg)
• Lead frontend development using React, Vite, TypeScript, TanStack Router/Query, Tailwind, and shadcn/ui
• Lead backend architecture with Python, FastAPI, CopilotKit, and PydanticAI
• Design data models and graph workflows using Neo4j (Neomodel) and PostgreSQL (SQLAlchemy)
• Build reliable APIs and integrations for agent workflows, AI generation, and DAG control
• Implement ingestion flows (GEDCOM, images, PDFs) and handle real-world data variance
• Architect graph visualization interactions (GoJS; possibly CytoScape or alternatives)
• Improve system reliability, observability, and performance across the stack
• Drive technical decisions, simplify complexity, and set engineering standards
• Support future builds involving OCR, LangGraph/CrewAI, and multi-agent pipelines
  • Example : Implement discovery and ingestion pipelines that unify searches across APIs and parse structured metadata for import, dedupe, and auto-tagging of primary vs secondary sources.
  • Example : Integrate verification and correlation engines (LangGraph) to compute confidence scores, detect duplicates, flag conflicts, and generate reports within the Copilot experience.

Preferred Experience

• Senior-level ownership of distributed or multi-service systems
• Strong experience with graph data models and performance tuning
• ETL/ingestion pipelines with messy or inconsistent real-world data
• Designing agent-driven or LLM-powered workflows
• Proven ability to simplify complex UX/data flows for end-users
• Strong judgment around boundaries, interfaces, and maintainability
• Ability to push back on scope, propose alternatives, and drive clarity

Success Indicators

• You independently architect and deliver large, chunked features end-to-end
• You stabilize and simplify core systems rather than adding complexity
• You raise engineering quality, reliability, and velocity across the team
• You bring strong technical judgment and communicate crisp, grounded decisions driving bug reduction

Responsibilities:

Own outcomes, not just tickets

• Lead a squad of 2–4 engineers (mix of senior/junior) to deliver measurable product impact
• Set clear goals and success metrics (e.g., latency/reliability/adoption), break work into small, reversible slices, and ship on a steady cadence

Design and build production systems

• Architect and implement .NET services/APIs with SQL Server for a multi‑tenant B2B SaaS platform
• Make pragmatic trade‑offs: idempotent writes, rate limiting, caching/ETag, indexing and query shaping, back‑pressure, and failure‑mode handling

Operate what you build

• Instrument services with logs/metrics/traces; hold the line on p95/p99 performance and availability SLOs
• Run incident reviews that produce systemic fixes and documentation (runbooks, dashboards)

Prioritise for the business

• Partner with PM/Design/Customer teams to translate goals into scope; cut or resequence work when data changes
• Keep stakeholders aligned with concise updates, risks, and owner/dates

Create clarity and accountability

• Set explicit expectations with your reports; give direct feedback; follow through with support and check‑ins
• Use lightweight mechanisms—PR templates, decision records, checklists — to make accountability routine.

Grow people and the codebase

• Mentor engineers via pairing, reviews, and 1:1s; create growth plans and celebrate momentum
• Keep standards high: tests where they matter, clear interfaces, and intentional debt management

Leverage AI effectively

• Use AI assistants to accelerate boilerplate and documentation, and verify outputs with tests and metrics
• Help the team adopt safe practices (no secrets, anonymised data, prompt discipline, simple evals)

Collaborate across the product suite

• Work with our iOS/Android/Web SDK teams to ensure that backend APIs and contracts are stable, well-documented, and easy to integrate.
• Support enterprise client integrations (often in sport), balancing reliability with delivery speed.

Hire and onboard

• Contribute to interviews and rubrics; onboard new teammates with clear goals, docs, and a first‑week win.

Qualifications:

Must‑haves

• Technical leadership: you’ve led a small team (2–4 engineers) to ship production software, setting direction, unblocking work, and owning outcomes end‑to‑end
• Practical problem solving: you start from constraints and business goals, enumerate options, make trade‑offs explicit, and choose the smallest reversible step that works
• Clear, direct communication: you set crisp expectations with reports, write succinct PRs/decision records, and give kind‑but‑candid feedback that changes behaviour
• Ownership & accountability: you finish hard things, leave systems better than you found them (tests, telemetry, docs), and make accountability routine rather than personal
• Flexibility & product sense: you can cut scope to hit outcomes, re‑prioritise quickly when data changes, and keep stakeholders aligned
• Learning mindset & AI fluency: you adopt new tools fast (including AI assistants) and verify outputs with tests/metrics, respecting privacy and data safety

Nice to have:

• Cloud & infra: Azure (or equivalent), CI/CD, feature flags, safe rollouts/rollbacks
• Experience across media/SaaS, SDKs, or high‑throughput event ingestion
• C# / .NET expertise: strong experience with modern .NET (.NET 8+), building and operating Web APIs; comfortable with Minimal APIs or controllers
• SQL Server depth: confident with schema design, indexing, query shaping, and concurrency (transactions, isolation levels, deadlocks, idempotency)
• Interest in sport and fan engagement (helpful, not required)

Our recruitment agency is partnering with a global B2B SaaS company to hire a Tech Lead for an AI-first platform that processes, analyzes, and enriches multimedia and social content for enterprise customers, including major players in the sports and media industries.

About the Project

The platform aggregates a wide range of content sources — social media posts, podcasts, online articles, images, and videos — unifying them into a single searchable index. It enriches content with metadata such as taxonomy, sentiment, storyline links, and contextual insights extracted via AI models.

These enriched insights are then used to power downstream actions: automated reporting, conversation analysis, and content generation. The system is fully AI-enabled and is now being rolled out widely across the client’s customer base.

We're Not Hiring an "Ad Manager"

We need someone who can diagnose WHY campaigns aren't delivering results - not just blame Quality Score, keywords, or budget. This role is not for someone who throws out jargon or buzzwords or the latest trends without connecting it back to data.
 

Most marketers will tell you generic fixes that sound right. Great marketers know the actual problem and can prove it.
 

This role is for the second type.

What You'll Own
 

Paid Advertising is in Your Blood

• Google Ads from day one, expanding into Meta Ads, and LinkedIn Ads (Reddit experience is a bonus)
• Client outcomes - Revenue. Pipeline. ROI. Not just CTR and impressions.
• Working directly with founder who has strong performance marketing background
• Operationalizing Client Success - Performance marketing service line operations. Help us define what tasks matter, what reports drive action, and what processes scale.
• Working directly with founder who has strong performance marketing background and can mentor/collaborate on complex accounts
   

You're not just running campaigns. You're contributing to the systematic delivery of the performance marketing function at a growing agency.

What Makes Someone Great Here

You diagnose root causes, not symptoms.

When results are bad, you know how to sort out if it's targeting, creative, offer, landing page, or something else. You can explain WHY you're making changes, not just what. You admit when you don't know and figure it out.
 

Test - Measure - Learn

• This is what was done.
• This is what happened.
• This is why it happened.
• This is what we will do.
   

You own outcomes, not activity.

If your accounts aren't getting results, you lose sleep over it. You push back (respectfully) when client requests won't work. You optimize proactively, even when metrics look good.
 

You think in systems, not just tasks.

You can explain what recurring work drives results vs. busy work. You build processes that others can follow to systematically drive positive outcomes. Trendlines of performance connected back to inputs. You pull levers and track outcomes via data-driven storytelling. 

Must-Haves

• 3+ years managing Google Ads and Meta Ads at scale
• Track record of driving business outcomes (show us the numbers)
• Can diagnose why campaigns fail, not just apply generic fixes
• Strategic communication - translate data into decisions
• Comfortable working autonomously in a small team
   

This Role ISN'T For You If:

• You think your job is just to "run the campaigns"
• You blame poor results on Quality Score without deeper analysis
• You'd rather follow "best practices" than think critically
• You need constant direction
• You care more about activity than outcomes
• You don't have experience owning the click to conversion journey with an emphasis on advertising ROI
   

What You Get

• Fully remote, work anywhere
• Direct work with founders, no bureaucracy
• Real ownership - you'll shape how we deliver this service
• Growth path to Head of Performance Marketing
• Culture that values outcomes over activity theater

About Us

• Lean growth marketing agency working with healthcare, tech, and professional services clients. We're building systems so we can scale without sacrificing quality. Fully remote, direct work with founders, real ability to drive results and have ownership.

  
   

This Role IS For You If:

• Paid advertising is genuinely in your blood
• You can systematically diagnose root causes, not just symptoms
• You're honest about what you don't know (and then go learn it)
• You want to build something, not just execute tasks
• You think strategically but can execute tactically
• Client success matters to you personally
