Learn more at getoptimum.xyz http://getoptimum.xyz
ABOUT THE ROLE
We're hiring a Jr. Software Engineer to join the Optimum team and turn product ideas into working prototypes. You'll work closely with our CTO and CPO to build, test and benchmark our solutions against the competition.
This role is deliberately focused. Your job is product discovery through code: build it, measure it, learn from it, and help us find a good fit for our users.
WHAT YOU'LL DO
- Build working prototypes of new ideas alongside the engineering and product team.
- Design and run benchmarks that compare our prototypes with competing solutions, and report results clearly.
- Work with the product team to understand how our users operate, where performance matters most to them, and what they'd pay for.
- Iterate quickly: ship a prototype, present findings and gather feedback, decide what to keep, and move on.
- Use AI coding tools such as Claude Code and Cursor to prototype faster, so you spend your time on testing ideas rather than boilerplate.
- Help shape the roadmap by bringing data and working demos, not just assumptions.
WHAT WE'RE LOOKING FOR
- Strong hands-on software engineering skills and a track record of shipping, such as open-source work or side projects.
- Strong hands-on full-stack engineering skills, from backend services and APIs to web front ends, with a record of shipping things such as open-source work or side projects.
- A prototyping mindset: comfortable building something rough to answer a question, then refining what works.
- A competitive streak and curiosity about how your work stacks up against alternatives.
- Comfort with performance measurement and benchmarking.
- Clear written communication and the ability to work with a distributed team.
NICE TO HAVE
- Experience with Go or another systems language on the backend, and React or TypeScript on the front end.
- Familiarity with real-time data systems, latency-sensitive applications, or high-performance workloads.
- Experience with blockchain networks, P2P networking, or trading and MEV workflows.
- Experience working directly with product or business stakeholders.
WHAT WE OFFER
- Work on hard problems at the edge of networking, blockchain market structure, and decentralized systems.
- Close collaboration with a small, senior, cross-functional team.
- Competitive compensation, equity, and flexibility.
- Flexible time off.
- Fully remote.
- Work from wherever you do your best thinking. Most of the team operates on ET or CET, so we look for meaningful overlap with those windows (at least 5 hours per day).
This is a 4 month contract with the potential to extend.

About Us
Constructor is the next-generation platform for search and discovery in ecommerce, built to explicitly optimize for metrics like revenue, conversion rate, and profit. Our search engine is entirely invented in-house utilizing transformers and generative LLMs, and we use its core and personalization capabilities to power everything from search itself to recommendations to shopping agents. Engineering is by far our largest department, and we’ve built our proprietary engine to be the best on the market, having never lost an A/B test to a competitive technology. We’re passionate about maintaining this and work on the bleeding edge of AI to do so.
Out of necessity, our engine is built for extreme scale and powers over 1 billion queries every day across 150 languages and roughly 100 countries. It is used by some of the biggest ecommerce companies in the world like Sephora, Under Armour, and Petco.
We’re a passionate team who love solving problems and want to make our customers’ and coworkers’ lives better. We value empathy, openness, curiosity, continuous improvement, and are excited by metrics that matter. We believe that empowering everyone in a company to do what they do best can lead to great things.
Constructor is a U.S. based company that has been in the market since 2019. It was founded by Eli Finkelshteyn and Dan McCormick who still lead the company today.
About the Position
We're looking for a proactive and highly organized Technical Project Manager to lead customer implementations across Constructor's product suite. You will lead onboardings for new customers as well as implementations of additional products for existing customers, owning each engagement from kickoff through activation. You will own the plan, the timeline, and the outcome, and you drive the people delivering it through a matrixed reporting structure. As we build toward an automation-first operating model, you will help standardize how implementations are run and increasingly act as a portfolio strategist, managing exceptions while repeatable, AI-assisted processes carry the routine work.
You will:
• Lead multiple implementations end to end, both new-customer onboardings and additional-product rollouts for existing customers, from kickoff through integration, testing, and activation.
• Take accountability for the outcome of every implementation, coordinating Constructor resources, customer resources, and partners, against a single shared plan.
• Run kickoffs, set milestones, track dependencies, and maintain a clear, shared view of status for internal stakeholders and the customer.
• Serve as the customer's primary point of contact through activation, setting expectations and communicating progress, risks, and changes in scope.
• Identify risks and blockers early, escalate effectively, and keep implementations moving toward on-time, predictable delivery.
• Ensure clean handoffs into implementation from Sales and out of implementation to Customer Success and Support.
• Maintain implementation plans and reporting in our systems of record so schedule, duration, and status roll up cleanly across your portfolio.
• Help build the repeatable processes, templates, and standards that let the function scale, and partner on the automation-first model as it matures.
Role Responsibilities: Technical Project Management
• Own the Outcome: Be accountable for the success of each implementation from kickoff to activation, whether the work is delivered by Constructor, the customer, or a partner, standing behind on-time, predictable go-live for both new customers and existing-customer product rollouts.
• Drive Every Contributor: Coordinate Constructor technical resources, customer resources, and partners against one plan, holding each accountable to their commitments through influence rather than authority.
• Lead the Customer Experience: Serve as the primary point of contact through activation, running a clear communication rhythm and building customer confidence from kickoff to handoff.
• Manage Handoffs & Risk: Ensure accurate handoffs from Sales into implementation and from implementation into Customer Success and Support, surfacing risk early and keeping delivery on track wherever the risk sits.
• Build Scalable Process: Standardize how implementations are run at Constructor, maintain accurate tracking and reporting, and help advance the automation-first operating model as the function grows.
Requirements
You Have
• At least 3 years of technical project management or onboarding project management experience, ideally in a SaaS environment.
• A track record of owning delivery outcomes end to end and holding cross-functional contributors accountable through influence rather than direct authority.
• Excellent organizational and communication skills, with the ability to run multiple implementations in parallel without losing the thread.
• Customer-facing confidence: you can lead a kickoff, manage expectations, and keep stakeholders aligned through go-live.
• Proven ability to prioritize effectively, manage competing demands, and maintain clarity under ambiguity.
Nice to Have
• Technical fluency sufficient to direct integration specialists and translate between technical and business stakeholders.
• Exposure to ecommerce, product discovery, LLMs and familiarity with concepts like catalog data feeds, integrations and APIs.
• Experience coordinating implementations that span internal teams, customer resources, and third-party partners.
