Company mission
To transform the way engineers work and enable them to do more of what they love doing: being inventors, creating great solutions, and solving problems.
Role
Who you are
- Even if you don't meet these criteria perfectly but believe you have lots to bring to the role, we encourage you to apply. We know it's tough, but please keep in mind that you don't have to match all the listed requirements exactly to be considered for this role
- You resonate with Synera's Core Values - they're central to how we work, and we'll explore them together in your first interview
- You’ve designed and shipped agent graphs in production with LangGraph or equivalent, including supervisor / sub-agent patterns, tool design, prompt iteration
- You’ve built or meaningfully contributed to an LLM evaluation pipeline: LLM-as-judge design, calibration against human labels, dataset versioning, and the statistical reasoning behind it (CIs, sample sizes, false positives)
- You write production-grade Python (using FastAPI and PostgreSQL)
- You’ve worked with at least two of the following AI platforms: Anthropic, OpenAI, Azure Froundry, Bedrock, or Vertex AI
- You’re familiar with Langfuse, LangSmith, or similar tracing tools
- You handle reliability when it shows up in your work, implementing retries, error handling, or graceful degradation
- You communicate clearly and push back when you disagree
- P.S. Synera is a place where everyone can grow. So, however you identify and whatever background you bring with you, please apply if this is a role that would make you excited to come to work every day, and be prepared to share with us how your perspective will bring something unique and valuable to our Agentic Ants team
What the job involves
- Most AI teams talk about evaluation. At Synera, you will own it: end-to-end, in production, for multiple real agentic products used by companies like BMW, Airbus, and NASA
- You’ll join the Agentic Ants team as their second native AI engineer. You’ll build and extend agentic systems alongside the rest of the team, including new tools, sub-agents and prompt iterations. But most importantly, you will contribute to an evaluation framework that gates every change: Golden datasets, LLM-as-judge pipelines, regression suites, production-trace mining. Your job is to prove that the agents the team is shipping can be trusted
- You’ll not only improve our existing software but also shape the next AI-native generation of Synera. Partnering with Danny and the wider R&D department, you’ll help the teams go deeper on customer insights data and come up with new ways to automate engineering work
- 👉 What a week at Synera could look like:
- Monday: Join our company-wide all-hands meeting to stay in the loop, then review Langfuse traces from the weekend and flag any new failure modes worth triaging
- Tuesday: Work on the golden dataset for the supervisor routing surface, curating examples, versioning the set, and writing evaluators with Ahmed
- Wednesday: Join a cross-team sync with QA and product to align on new eval coverage for an upcoming agent feature, then push a CI integration so eval regressions block the next PR
- Thursday: Show off your latest work to other departments in the sprint review, use your lunch break to go for a quick run, then kick off sprint planning with the Agentic Ants
- Friday: Pair with the AI and software engineers on extending our agentic system, then write the eval that gates the change before it ships
- ⚡ In 6 months:
- The evaluation framework is live and in use across multiple agent, CI gates are blocking on regressions, and the team can actually trust the results
- You’ve shipped multiple meaningful changes to the agent graphs (new tools, sub-agents, or routing improvements) that are measurably better in production
- ⚡ In 12 months:
- The agents improve themselves: Production traces feed continuously back into datasets, and the improvement loop is running without manual intervention
- You co-own at least one agent surface with the team and have become the go-to person for evaluation methodology at Synera. The combination has measurably improved product quality
Our take
Synera, formally known as Elise, is a German-founded engineering software company that develops platforms and tools for manufacturing companies. Off the back of the company's ethos to help engineers do more of what they love, Synera automates processes and leverages low-code, open and integrated software to help companies as large as BMW and Hyundai get more done faster.
Off the back of its 2026 funding, Synera has been enhancing its platform, strengthening deployment capabilities, and working to expand its customer base into new market regions, such as France. The company already claims to save engineers up to 90 percent in time savings on ad hoc tasks, enough incentive for the auto and travel manufacturing industry to invest in it. Interestingly, the Alfred Wegener Group, which conducts research in the Arctic and the Antarctic, is a parent company of Synera, influencing its core motive of improving engineering efficiency for time-sensitive work.
