EKTOS is a dynamically developing company that works with many different clients from all over the world in such areas as healthcare, finance, transport, agriculture, navigation, travel, banking, and many others.

We develop in C / C ++ for various microcontrollers and processors with and without an operating system and create ready-made working prototypes of devices with our departments.

Working at EKTOS will allow you to see projects from both hardware and software sides and get a high level of skill. We care about creating an informal, safe, and open environment in our offices and we offer a competitive salary.

S&F AI Automation started as an internal R&D team, using AI to solve our own company's business problems. After building real expertise and a portfolio of delivered projects, we're now turning this into a practice that helps other businesses level-up their operations with AI.

We are a team of AI geeks who see our work as a way to express creativity. We are looking for someone who shares this obsession and will raise the bar: challenge our architecture decisions, bring tools and techniques we haven't tried, and help us turn prospects into projects we will enjoy engineering.

You'll join a small team at the stage where everything you do has outsized impact. This role brings senior-level engineering capacity to the team while also adding the presales muscle needed to grow the client base.

Technical requirements

• TypeScript (Node.js) OR Python — production-level proficiency in at least one.
• Building LLM-powered applications: agents, assistants, multi-step workflows, structured outputs. Prompt engineering: function calling / tool use, chain-of-thought. RAG: document ingestion, chunking, embedding models, relevance tuning. LLM SDKs: Anthropic Claude, OpenAI. Frameworks: LangChain, LangGraph. Building and integrating MCP (Model Context Protocol) servers.
• Agentic architecture: agent loops, tool orchestration, memory management, multi-agent systems. Knowing when agents are justified vs simpler alternatives.
• Workflow orchestration: Temporal (readiness to build durable workflows), n8n (low-code automation). Vector search: Qdrant, AWS OpenSearch, embedding pipelines, hybrid search.
• API & backend: FastAPI OR Fastify / NestJS. REST APIs, webhook integrations.
• AWS: Bedrock, SageMaker, Lambda, OpenSearch. Cloud ecosystems: AWS (Anthropic), Azure (OpenAI), GCP (Gemini) — platform-exclusive models and services. Docker, IaC basics, VPS provisioning, serverless patterns.
• Zero Data Retention policies, data isolation, private cloud deployments. LLM safety: guardrails, hallucination mitigation, prompt injection protection. Ability to articulate security posture to enterprise clients.
• LLM cost optimization: token budgeting, semantic caching, model routing, fallback strategies, choosing the right model tier.
• Active use of AI coding tools: Cursor, Claude Code, GitHub Copilot, or similar.
• Nice-to-have: Voice AI (STT/TTS), multimodal AI (OCR, vision-language models), LLM evaluation frameworks.

Who you are

You have 3+ years of experience in a technical presales, solutions engineering, or solutions architect role. You have led discovery calls, scoped proofs of concept, and handled technical objections in B2B sales cycles.

You have hands-on experience building AI-powered applications in a professional setting, not just personal experimentation.

Your English is fluent at C1+ level. You can lead live calls with English-speaking stakeholders and handle nuanced technical questions without hesitation.

You communicate consultatively. You guide stakeholders to clarity instead of overwhelming them with options. You can easily explain a complex concept to a non-technical audience.

You take ownership and initiative. You do not need a heavy playbook. You identify gaps, flag risks early, and move things forward. Much of the presale process is still being built, and you are comfortable shaping it as you go.

You are adaptable. You are comfortable in a small team where priorities shift, and where the role will evolve as the practice grows.

What the work looks like

Provide technical depth during presales.
You join prospect calls alongside the department head and own the technical side of the conversation.You probe for technical constraints, assess feasibility in real time, identify integration points or data dependencies, and start forming an architecture before the call ends.

Design AI solutions that match the actual problem.
You translate business context into an architecture with realistic scope and effort estimates. You know when prompt engineering is enough, when RAG is needed, when fine tuning or custom development is justified, and you can explain why.

Connect AI to the tools businesses already use.
You design integrations that make AI solutions practical: pulling data from CRMs or ERPs, syncing with cloud drives or email, pushing outputs into Slack channels or project management tools. You think in terms of end to end workflows, not standalone modules.

Contribute to building, not just sales.
Between engagements, you write production code, guide architecture decisions, and help the team ship client and internal projects. This role carries engineering weight, not just advisory influence.

Outcomes over the next 6–12 months

Strengthen the team’s engineering capability
Provide architectural guidance on client or internal projects so solutions are more reliable and scalable than what would have been built without your input.

Ramp up as a presales partner within 30 days
Independently lead the technical portion of prospect calls by the end of month one. The department head should be confident you ask strong discovery questions, communicate clearly, and propose relevant approaches without heavy coaching or supervision.

Help close the first $80k in new revenue
Participate in presales engagements that result in at least $80k in signed project value within the first six months. This includes Discovery Sprints and follow-on projects that come from them.

The product is a low level, performance critical system built around DPDK and modern systems programming practices. It operates at line rate speeds, processes tens of millions of concurrent flows, and performs deep L7 inspection, traffic classification, and shaping in real time.

In this role, you will work close to the hardware and network stack, owning critical parts of the packet processing pipeline and performance optimization, in collaboration with senior system architects and infrastructure engineers.

Responsibilities

• Design and implement high performance DPDK RX/TX pipelines with zero copy forwarding

• Build per core, lock free flow tables supporting tens of millions of concurrent flows

• Implement L7 protocol parsing including HTTP, TLS SNI, DNS, QUIC, and custom protocols

• Develop application and traffic classification using signature based and ML assisted approaches

• Implement traffic shaping and QoS mechanisms such as hierarchical token bucket

• Integrate high performance pattern matching using Hyperscan

• Perform deep performance optimization using SIMD, cache tuning, and NUMA aware design

• Profile and debug performance bottlenecks using tools such as perf, VTune, or similar

• Work closely with hardware, infrastructure, and backend teams to ensure end to end system efficiency

Requirements

• 5+ years of hands on experience with DPDK in production systems, not research or prototypes

• Strong systems programming background in C++ or Rust, with willingness to work in Rust

• Deep understanding of poll mode drivers, mbufs, lockless data structures, and NUMA architectures

• Solid knowledge of TCP/IP stack internals and packet level protocol parsing

• Proven experience building and optimizing low latency, high throughput network systems

• Strong debugging and performance analysis skills

• Ability to work independently on complex, low level technical problems

• English level sufficient for technical discussions in an international engineering team

Nice to have

• Experience working at networking vendors or telecom equipment companies

• Background in carrier grade DPI systems

• Hands on experience with traffic shaping or QoS implementations

• Experience with ML inference pipelines such as ONNX Runtime

• Familiarity with eBPF, XDP, or kernel bypass techniques

• Experience with hardware offload technologies such as Flow Director or SR IO V

This is a long term opportunity to work on a technically extreme system at the core of a growing Canadian startup, solving hard performance problems at scale and building software that operates at the limits of modern networking hardware.

• Collaborate closely with the design team to translate Figma designs into high-quality, responsive user interfaces and A/B tests
• Improve observability and error handling across the frontend stack
• Refine and implement proper CI/CD pipelines to streamline our development and deployment workflow
• Mentor, support and lead other frontend developers, conducting code reviews and sharing knowledge

What we’re looking for:

• 7+ years of JavaScript experience
• 4+ years of React experience
• 4+ years of Next.js experience (ideally with hands-on work with App Router or Pages Router)
• 3+ years of TypeScript experience
• Proven experience with migration projects - ideally having led or played a key role in SPA to SSR migrations
• Experience deploying and managing applications on Vercel
• Solid knowledge of crash analysis tools and production monitoring
• Experience designing and implementing caching strategies for high-traffic, globally distributed applications
